this v10 tdi and the v12 tdi from audi are a marvel of engineering everything is robust and made to last quite a long time (idk what happened to this engine in particular)
I’m replacing the head gasket on my Audi B6 3.0 AVK. While it’s a big pain, I’ve actually come to appreciate the design. One timing belt two run all cams (aka 2JZ), modern variable valve timing on both intake and exhaust, 5 valve head still, variable intake runners, no rockers to worry about. Aluminum block with cast iron liners. However, the cooling lines, vacuum lines, PCV and secondary air injection is a rats nest!
@@300DBenz it’s odd because this was about the same time as those. It seems like it was the last timing belt design, but the description of the engine said the block was derived from the V8. Not sure if that was the older V8s or the B6 S4 V8.
@@SlavkaZhuravka it is terrifying as a mechanic, if you miss something and it has to come out again you are in deep shit. Not just paid hours you're missing out on, but the schedule for the whole week is f'd.
@Scouter98 Okay, that was a thing, which I wasn't thinking about. As an office rat it was hard for me to imagine exactly that use case. But indeed, once you have forgotten literally anything here below the cable harness, you have to disassemble half of the normal engine
Im literally doing this job at work, had bad O2s, all fuel lines rotted, p/s pump leaks, oil leaks. Have the engine out and almost ready to go back, great timing for this video!
I've done all the work on my 2008 v10 and once you've pulled the engine 2 or 3 times it gets easy/faster and just accept if the engine or anything within 3 feet of the engine needs any work the motor has to come out. It really isn't worth fixing these days but once you drive one when it's perfect it's awesome and towing well it acts like nothing is even behind you. I normally tow somewhere around 18klbs (have towed heavier) my trailer is pretty heavy and with two cars on it doesn't sweat much but you wear through brake pads and rotors fast. One day I'll try and find an upgrade for the brakes that makes sense and won't be gone when I need pads or rotors again. I'm glad whoever is paying you to fix their baby is doing it. These were really built to last they just missed a couple of things. Yes they aren't worth much these days but if you find one that's been well cared for they bring pretty good money. What other VW had orange interior lol thank you for keeping one alive and not sent to the scrap yard. You definitely need to be able to afford of at least make them somewhat cost-affected to keep.
I was the first VW tech to remove this engine on US soil. VW engineers came out to document the job as the VW Elsaweb didn't have service informatiom. Right turbo failed at 17k. Total warranty time was about 30 hours. Took 60 overall with diag included.
@iamtheoffenderofall not entirely true, I know some porsche techs are paid hourly on the West Coast. It's a shame because there is zero incentive to do a job like that.
Fun fact, this engine is basically 2 2.5 Tdi's stuck together, that's why you have so many gear, they're doubled plus the ones to synchronize them, camshafts, heads, injectors are all the same, not sure about head gaskets, the block is where the differences start. Also let's not forget there is a V12 Tdi from the Q7, that would be nice to see on this channel. Great job Charles
blok is the only difrent injectors headgasket etc all the same turbo is same size as axe 174 bpc 174 hp engine only diffrent shape cams are the same pistons same
they could have took slightly more time to maybe develop electric driven accessories instead of literally complicate everything. Thats a gigantic pile of mess
@@alanmay7929 the base engine that they derived the V10 from, uses timing gears, so it’s not much they could have done. The V10 is not a a designed from scratch engine, they just stuck 2 5 cylinder engines together
As a person that daily drives a 2008 Touareg V10 TDI, you just have to ask yourself “what’s the worst? It’ll blow up” and you’ll never be disappointed (I dropped my motor last weekend)
Pretty much. I have a 2010 in Brisbane and had the motor out for 6 months of last year just doing engine mounts and welding up exhaust manifolds. They are a unique piece of automotive history. Good luck with yours 🤞
Haven’t had to drop the engine on my 07 v10 Touareg yet but man it is a challenge for sure to do anything with the engine in the car recently did the alternator and emissions deletes (egr dpf) thankfully can all be done in the car but man what were they thinking when they put that together 😂 I do love the car and plan on keeping it long term it’s a fun off-roader it’s unusual and it’s rare
my second year as a tech at a vw dealer back in 07 we had huge storms that year and one of them got hydro locked, touareg got towed in and insurance was paying 37 hours to replace the motor, everyone in the shop was hiding from that job, i ended up doing it took me 5 days to replace the engine, that was the first time working on a v10 tdi and the last time. lol
My girlfriend who has literally zero automotive knowledge is starting to enioy watching some Humblemechanic with me! She's very supportive of a project car idea...all thanks to us binge watching your vids! Long time follower for about 8 years..keep up the great work!
Ive worked on a few of these. Starters are engine out. I can do the passenger side tandem pump im chassis, but the drivers side the engine needs to drop. They aren't very common, and they remind me a lot of the lml duramax to work on, from the standpoint of your order of operations are critical. Putting them back together in the correct order is super time consuming and there isn't enough of them rolling through to develop the muscle memory. Speaking of duramax, the duramax engine uses lots of 14mm
I used to work for Deutz, and their engines are a breeze to work on. They had 3,4 and 6 cylinder versions as well as air cooled and liquid cooled. Those are from a very different era when German engineering actually commanded respect, super simple and very reliable. It's a real shame you mostly find those engines running airport equipment, reefer units, generators and some old farm tractors. That's the case at least here in the States.
@@michaelbolton1090you can do the starter in the car but it sure is a pain in the ass you gotta take the passenger side engine mount off and a few other things you’ll be working in a blind hole obviously but it is possible to do it that way it has been documented at this point as well but yes this engine is extremely hard to deal with (I love mine)
A worn camshaft is a result of leaking fuel injectors. The diesel leaks into the engine oil and the highest sheer wear location suffers first. These are the camshafts and lifters. Replacing the camshaft and lifters does not fix the problem because the injectors are STILL leaking. You’ll need 2x new cylinder heads, 2x camshaft and lifter kits and an aftermarket injector bracket kit from Germany to prevent it from happening again. 👍 Awesome engine !!
If a V10 TDI engine can pull a 747, and HM can pull a V10 TDI engine, then by the transitive property of pulling, Charles can pull a 747! Congrats on having, I think, the only V10 TDI teardown video on UA-cam -- Either now, or well into the future. 🏅
Check out the german YT channel FixitAri. He is a pro and recently uploaded 6 videos on removing, repairing and installing a V10 in a VW Phaeton. The V10 is a nightmare. Almost everything is an engine-out job, to include replacement of the starter. Initially, it was designed to be used in the Touareg, but not in the Phaeton. But stubborn Ferdinand Piech insisted that his engineers shoehorned it in, which required a lot of alterations of the engine. It is great, as long a it runs. But beware if something breaks, then your worst nightmares will come true.
One thing that everyone should think about in this scenario: Imagine if the customer had agreed to do the job at whatever shop diagnosed it. The amount of added parts like that cross over, alternator harness, glow plug harness, etc would have absolutely wrecked this estimate. Plus the likelihood that all those parts are still readily available probably isn’t great. The shop would get the engine apart and possibly not be able to put it back together for months if the parts are available at all.
@@HumbleMechanichow available are parts for this engine these days? Hard to find, unobtanium or has to come from Germany since no one stocks them? I'm kind of interested in one of these as a project car since they made more of these than Phaeton's.
@LoneWolfSparty last one I did the tandem pump was tricky to find and had to be sourced aftermarket. Everything else, the turbos and manifolds (they crack) were available through vw.
@@LoneWolfSparty At this point, you can still get most of the parts. Most of the Seals are available from VW still and things, that are shared with the 2.5 TDI are also easy to get aftermarket. It's the V10 specific stuff, that can be hard to get, especially after VW stops selling it.
I have an '04 V10 with 596k km on it, It's my absolute most favorite vehicle to drive, but there's a reason I have a second one sitting around as a parts car... Had to do most of this fun work on the top side to get the alternator out to be rebuilt and fix the oil leak from the pressure sensor that was flooding the valley (probably also why the alternator died). cylinder 5 glow plug is bad and I'm not willing to try and get it out to have it break, when it starts fine with 9 others.
Some say... Our dear Charles is an Alien... After fixing the mothership... He relaxes and tears down a V10 TDI... COOOOL STUF MAN... THANK YOU BETTER THAN NETFLIX
Here too, in France when you talk with some car enthuisiasts even if they are not VagFans we all remember this GOLDEN ERA of VAG around 2000s - 2012s : V5, V6 TDI, V10 TDI, V12 TDI , w8, w16... Audi r10 at LeMans 2006 with the V12 TDI. now everything is "e". Find a V12 TDI too please !!
As a guy, who loves diesels and especially Pumpe-Düse diesels, this is my all-time favorite engine. To me, it's an engineering masterpiece, especially when this thing is sitting inside the engine bay of a Phaeton. Physics kind of dictates that they aren't easy to service... But here in Europe you see a lot of these engines in cars with 250k + miles for sale, where it's very apparent, that they were run on a repair budget of basically 0.
I've replaced the cams in a number of these and can replace them without pulling the engine. Though it is NOT a fun job. You can delete the EGR setup. I also modified the turbos on one for a larger downpipes. We were able to get it up to 12 PSI after. Very fun unit to drive. Part of the reason why the camshafts wear has to do with the way the cams are ground. If you replace with a true hydraulic grind camshaft from Colt Cams and put in new lifters (if using the black nitrided lifters remove the 1 spring which gives a valve lash).
Fun fact: the reason why V10 TDIs go down and wear through camshafts has been blamed on the type of oil that people would mistakenly put into these engines. Like Charles said, these are PumpeDüesse (close enough) they are somewhat different and If i recall V10 TDIs require VW 507 oil, people would put regular 502 or 504 and it wears the cams. If you use the correct oil V10 TDI will run to 400k miles easily. As long as you replace the turbos at least once.
Actually the oil that VW calls for doesn't have enough anti wear additives. If you run a regular synthetic diesel oil like Rotella T6, they don't have the issue. Same with the other Pumpe Duse engines.
@@thijs_rallye8621 No, all wrong. 504.01 does not exist.Special oil for this engine was 506.01 (0w-30 ACEA C5), other PD engines had to use 505.01 5w-40 (specificaly for PDs). Both of them later "superseeded" by 507.00 5w-30 or 0w-30. From my opinion 506.01 engine oil was introduced because of better lubricating in cold starts etc. providing more protection of the alusil (nikasil) cylinders when oil was cold. This thinner oil then resulted in less "pressure resistance" on the cam lobes. Otherwise I can't answer the question why R5 (2.5 TDI PD) and V10 (5.0 PD) are way more susceptible to camshaft wear compared to other PDs (1.9 and 1.4) that can easily go almost double the kilometers to the same camshaft wear...
@@vasek987 You are absolutely right, I mixed things up, I meant 5w40 505.01, which wsa superseded 5w30LL as you say. As for the wearing, from what I've understood is lugging the engine doesn't help the cam wear. I can imagine an engine with more cubic capacity will be lugged harder than a small capacity engine.
Even if I had the experience of a master mechanic, I would open up that engine bay and just go “NOPE”. This one looks like as much labor as a hyper-car.
Hey Charles, this is precisely why I tune in to your channel, as well as Paul’s. You both have a profound appreciation for the intricacies of human engineering, especially when it pertains to engines. I once shared my thoughts on VWvortex, but after facing a barrage of trolling, I decided to respond to them. Unfortunately, that led to my ban from the site for criticizing electric vehicles and highlighting our current consumption of precious metals, leaving little for the engineers of the future.
Hi Charles. I feel conflicted when I watch your videos, like this one. You do sound like a ‘humble mechanic’ but you clearly have the big brain of a highly intelligent engineer! I’m sure in another life you would be designing these amazingly complex machines instead of maintaining them, assuming this isn’t the case already! As a fellow engineer I thoroughly enjoy your videos and truly appreciate the hard work and effort that goes into making them. I also think VW should give you some type of award for displaying the engineering that goes into their vehicles. As you explained, even this incredibly (and perhaps, unnecessarily) complex engine demonstrates some impressive engineering.
0:47 - 0:51 Already contemplating your life decisions? Thank you so much for all that hard work and all the hard work you are still going to put into this! That was super cool!
Charles this was such a cool video, thank you for going through the trouble to share this with us. This one really hits home for me - my VW love all started with the 1.9 TDI (a PD!), my first car... I didn't know ANYTHING about cars before I got t, and as luck would have it, that first car had a bad cam in it, JUST like this one (well, caught it a little earlier, phew). I learned so much not just about cars but specifically about early 2000s VWs, and went from never having done an oil change to having replaced the cam and lifters and re-timed the motor myself. That's about when I found your channel, and there is so much I would not have done right were it not for your content.....and the rest is history. Thank you for continuing to keep the VW love alive, always stoked for your next videos and whatever you're up to. Thank you Charles!!!!
Was torn between this and the 3.0 v6 tdi when picking a Touareg back in 2018. Liked the idea of having a v10, but decided it was a bit more practical to go with the v6. I have been in love with it ever since and this video just made me love it more lmao.
This engine was an engineering marvel. Never want to work on one, but it was a truly incredibly successful in motor racing. This V10 and the V12 TDI were so dominant while racing in the LMP1 series (R15 and R18). Very interesting to see one taken apart!
I have two of these, an 04 and an 06. Yes, i'm a glutton for punishment. I just finished replacing the cams and lifters on my 06. For those considering camshaft repair; This job can be done in situ. Place the front end in service mode, remove the false firewall and use a small pulley remover/installer tool. BTW that stupid coolant junction is almost impossible to remove without breaking. It appears the camshaft issue is likely due to the tandem pumps leaking diesel into the crankcase....
It looks like the lifters are supposed to rotate, is that right? The reason I ask is if they are, that one he showed that was bad looks like it stopped rotating and got excessive wear in one location.
Mine didn’t have tandem leaks and they were worn at 105k miles, exhaust way worse then intakes. I’m now at 210k with colts so I’m curious about doing an inspection on them.
@@JoshsJettas Yeah, the Colt guys are pretty sure it's bad OEM cam profiling. I have also noticed it tends to be the exhaust side that wears. Perhaps it's not fuel leaking past the pumps.
6:04 "Old air-cooled beetles are probably the most serviceable engine ever made. Compare that to this; the least serviceable engine ever made." And people wonder why VW is circling the drain. Thanks for the video Charles - your teardowns are always a treat!
If you tried to building a motor with the reliable power this thing has, and have every chain and cog and plug and spinning shaft readily accessible, it would unfold and sprawl out across a 10' x 10' room. The smaller things get, the simpler they and the less power they make, until you start getting into cutting edge material technology.
@@guzziwheeler All big car world manufacturers are, google it. Global economic crises and China's industry picking it up make cars hard to sell these days.
That thermostat brings back memories. Bought one of these back around 2008 at auction in Florida while visiting my mother. Had over 120,000 miles but looked great. Went to drive it the hour or so back to her house. Ran fine the first 5 miles on the way to the highway, then once ON the highway, the temperature gauge starting rising. Eventually the overheating light came on so I pulled over and had it towed the rest of the way back. Turns out the fancy electronic thermostat was bad and stayed closed all the time. Not having any tools with me there, and not wanting to dump $1,000 in a thermostat job at a VW dealer there, I figured that if I kept the speed at 50 mph, the temperature stayed just above the middle mark on the gauge and I could theoretically drive it 1,000 miles home like that. So that's what I did a few days later. 50 mph at about 1,200 rpm for over 22 hours and probably P.O.ing a lot of drivers behind me on I95. The only good thing is I was getting over 30 mpg in a heavy V10 diesel. That must be a record.
2004-5 was probably the coolest year for all the cars. Each model had something crazy going on and the flagships were insane. this was a very in depth look at a VERY technical engine. glad we got to see 2 Charles' at the same time!
I knew you were going for the joke "on the table, off the table" and I genuinely laughed lmao. You do an awesome job talking while you're working. It's interesting because you're enjoying yourself.
Love your videos! I just bought a 22’ Mk8 GTI S DSG with 32k miles (got it for $22k 😀) the muffler was deleted but I have the original muffler. Is a muffler delete potentially damaging to the vehicle or is it okay? Should I get it put back on? Get it tuned?
The dsg is a pain in the ass it's likely to breakdown service it every 50tkm and it doesn't like stop and go but it's still a great transmission fast gear shifts A muffler delete hasn't many bad things Potential for Reduced Back Pressure While some performance gains may be seen excessive removal of back pressure can negatively affect engine performance in certain vehicles And you lose your warranty at least in German
Iam currently a new-ish VW tech at my local dealership, I've been there for a year Ina half now and Iam honestly really enjoying it! I've been getting told recently how much of a nightmare the Touareg is to work on, and no matter what is wrong with it, it's always such a pain......now I understand lol. I love your vids can't wait to see more.
As a tdi guy, for me this is the crown jewel of diesel engines. Yes, it's complicated, hard to work on. Some consider a $ pit, but the potential if given for these beasts is nothing short of badass! The exhaust note with a decent pipe setup is crazy cool! Loved these diesels when they 1st came out and still do. Thanks for this video! Well done 👏
That's insanity!!! I love the v10 tdi and always thought someday I'd pick one up. After watching this video, not a chance!!! I thought bmw engines were complicated! At the same time, like you said, you cant help but admire the engineering to make it all work! I bet they got all done designing it and one guy was like, "wait... where's the alternator?" And the other guy said "Oh....crap." Very creative design thats for sure!
That whole 'early 2000's' era of VW's was awesome. I thought the V10 TDI was an amazing engine, but now I look at it and think it's just overengineered with a bunch of parts that are designed to fail. I had a 2001 Golf TDI 1.9L that went 400K miles before I sold it, and that thing had never had the engine apart at all. It doesn't look like the V10 had that kind of longevity.
It does easily. Do the known work before it all breaks and you'll find a lot of them in cheap Touaregs here in Germany with up to 500.000km. Normally our cars go to the east of Europe at 300.000km
But.... To do the necessary work, the engine has to come out at one point or another... That is a really poor argument to make imho. A well designed engine needs basic maintenance that can be done WITHOUT having to pull it out and spend days faffing about. The V10TDI is NOT well designed. If money and time are of no concern LITERALLY EVERY SINGLE ENGINE EVER BUILT could run fro a million km and more. Just rebuild it here and there, boom, you keep going. It's that easy ;)
@@leviathan5207 Pretty obsolete point, right? A rebuild is not the engine running long. If a non rebuilt V10 lasts 500.000km but Cummins and Powerstrokes die left and right, I choose the more complex engine. And if you say basic maintenance, the V10 NEVER has to come out to do BASIC maintenance. Why would you? No timing chain or belt, so your basic maintenance is reduced to oil, water, brake fluid, all filters, every four intervals the rubber coupling of the alternator for which the engine does not has to come out and if you do PD-injectors at 500.000km when they first fail, the engine stays in as well. I cleaned all injectors preventatively at 230.000km while cleaning the intake and doing both took me 12 hours. Alternator took me 2 hours. Thermostat 1 hour, turbocharger actuators took me 3 hours per side with the engine in. And none of that is basic maintenance. This is an insanely complex engine and it's shoe horned in there, but it's by no means a bad design. Not at all. Considering it has the engine bay volume of your average US car glovebox, it's surprising it does not die the heat death earlier. You could fit two V10s in a Dodge Ram engine bay. If you were to fit only one, you also would never have to drop the engine. So your argument is moot.
@@GERntleMAN Seeing this video, reading your arguments and owning two 1.9 PD, I will agree in your conclusion! This sounds like a bullet proof engine! Seeing those timing gears, no additional service needed!
@@tommelomme6761 I wouldn't go so far as to say it's bullet proof. Since it's an aluminium engine it's a little more sensitive to bad fuel and heat. The classical PD engines are almost always iron blocks and either iron or aluminium heads. Much more heat tolerant and although an AluSil cylinder surface is much harder than any aluminium or steel one, they still can get scored. So you really need to treat the V10 like the engine it is, a rather highly developed luxury engine which saw only use in two cars. Do the fuel filters, do the upgraded PD holders and avoid high heat input. There is no room for the heat to go in this engine bay. That's the reason for the oil leaks for example. Local heat hotspots are also the problem for the tandem pump which bends and then starts to leak. Only changing the gasket doesn't work for long. Heat also kills the turbo actuators. The turbos themselves fail rather seldomly, but the actuators do because of heat. This engine would be double or triple as reliable if put into a giant engine bay of an American car. And last but not least, don't by the DPF and EGR cooler version, meaning the BLE. There is so much heat in the V thanks to this fucking EGR bullshit, it's insane.
Just wanted to say this is such a cool video! If nothing else VW can be appreciated for its eccentricity and it seems that you appreciate that too. You seem to be right in your element here, having a positive attitude and laughing things off when many of us would be tearing our hair out and inventing new four-letter words. Awesome!
I like working on mine too. It takes me 30min to get out both intakes and the fuel rails. Had to do it 6 times to get the rails to not leak after taking them out the first time. The o-rings, which you can't get anymore, never really sealed so it took a while to get the perfect ones. I do everything without power tools. Always with hand.
Ive done a few of these. Starters are engine out, drivers tandem pump is engine out, turbos and manifolds are engine out. Even the upper 02 sensor is engine out. I think typically the repair bills are anywhere from 8-12k. They are super cool though! Sometimes vehicles dont make financial sense (most VAG stuff) but we like the punishment. Also duramax uses a lot of 14mm, and bedplates and gears are super common on diesels, it gives them a ton of strength. The big advantage of diesels is the strength of the engine, its like buying a built race motor because they run all the boost at super high compression.
I own a v10 tdi Touareg and work on it my self tbh I find the challenge fun the parts aren’t too too bad for what it is it’s the labor that’s nuts it obviously isn’t my only vehicle so when it does need work I just wait until I have the time and fix it I wouldn’t want to own one of these as my only vehicle for sure
This was so cool,i would never cover those beautiful valve covers with composite but i see what they did,there is a space between them. How everything is layered on the block holy smokes that thing has never breathed,its so complicated its outta my league.. .
Recently bought a used EGR Cooler, cleaned it as thoroughly as I could and had it installed in place of my “insufficient flow” in my 2.0 235,000km and the only non fully blocked holes have pin prick sized holes. I’m convinced whoever designed it decided it would be a point of failure and would create more car sales…. Runs great now… plan to sell the one taken out once cleaned, since the labour to replace it in a 2012Tiguan with AWD in very very costly… 7 hours labour…
17:20 the real reason for adding turbos is because diesel emission requirements forced manufacturers to lower compression. The entire benefit of a diesel engine is being able to run a very high compression ratio. By lowering the static compression ratio, you lose power and torque output but you can improve NOx and run a smaller camshaft for improved low end power (swirl flaps are even used now for better low speed combustion). Also, Diesel fuel actually takes longer than gasoline to burn. This makes designing a high speed diesel more difficult. You can play around with fuel timing but this also increases cylinder pressures. So adding a turbo allows you to force more air into an engine than it normally would do so at 1 atmosphere. You can get better power from the mid range and higher
I was stunned you said only $10K to get the engine running again... I'd spend that in a heartbeat for that beast. I've spent way more than that on keeping my Range Rover running... and now it's dead again 😀
@@HumbleMechanic I get it, however at this point don't you think it would be prudent for any V10 to have it's whole intake/exhaust/fuel system to be fully cleaned/replaced anyway? If it were my car, I'd rather bet the $10K on something I know rather than someone else's possible 30sec from disaster car. I've probably dumped ? 2x the "worth" of my RR into it... because I know it. I'm up to $3K in parts this last summer on the V8 4Runner because I know the car... I don'y fully buy into the you can just get a "good" used one for the cost of fixing this one.
Great video as always! Would like to point out that diesels dont use throttle bodies/valves. They are called ASV (anti shrudder valve) and it has totally different function then throttle valve. it is an on/off valve. it opens when you start the car and closed at shutdown (for smoother shutdown) and as protection for runaway diesel.
Diesels do use throttles. Maybe they didn't back in the noughties but they do now, for throttling down intake airflow. Anti-shudder valves are probably just on/off while throttle valves can be controlled 0-100%.
Super cool video! It's wild to see all the crazy engineering that went into packaging all of that together. The gear drive end reminds me a lot of the locomotive engines I work on, but with those there's a massive set of gears on both ends - crank, cams, turbo clutch, oil pumps, water pumps, engine overspeed...
Thanks been hanging for a V10TDI tear down, absolute amazing engine, as an engineer I'm in awe. had my 2004 V10 for 10 years and had over 300000km on the clock, sadly it was the failed electrical insulation which did me in. I'd bet that the cams failed because somebody used the wrong oil, VW506.01 only in these things.
That thing is a nightmare. I can’t imagine the cost to replace an alternator or an AC compressor. There is not one thing on that motor that is wallet, friendly.
You putting a lot of gems out sire and the time and effort to do something like this deserves a superthanks The Wiring KT video you did was my favorite until this one. Big ups to you
Wow, I really appreciate this teardown video. Volkswagen has always been the company of how technically difficult can we do this job? I've had a few from a beetle to a Dasher, to my B5 wagon, and my 2012 Passat. The 2012 has a 2.5 5 cylinder and that's pretty cool.
Interesting how my Dads 1960 VW Beetle that has been in the family since new with over 1 million miles on it, has only had the engine out to install a new clutch and new push rod tubes is still going strong whereas newer VW's like this one is falling apart after only 200k miles? Then VW wonders why Honda and Toyota outsell them 20 to 1. Sad truth, because I like VW's but I understand why people shy away from them too.
"Then VW wonders why Honda and Toyota outsell them 20 to 1." In the USA perhaps, but globally the VW Group of brands sell very well! Toyota Group is the global number one, VW Group global number two. But very interestingly Toyota Group (Toyota + Lexus) is only in 5th-6th position for auto sales in Europe, much lower than their number one position nearly everywhere else.
@@TassieLorenzo yeah here in the USA VW sales are so low I'm surprised they still sell cars here. For example last year in the USA VW sold around 8000 Golfs (we only get the GTI/R) compared to over 300,000 Toyota Corollas. VW has a poor reputation for reliability here which really hurts the brand.
@@eppyz the plastic. Everywhere. The most hilarious usage is in the oil breather system on turbo engines. People stomp on the gas, eventually the plastic cracks, engine light/misfires. Should've used metal where it mattered. But they build now so you're getting a new car every six-seven years. Thankfully the Asian builders think otherwise.
@@timewa851 Well I would agree to disagree with you. Your implying that ONLY VW uses plastic bits and cheapened their cars and what not. Well, EVERY car manufacturers has done the same, even Toyota and others. Have you seen under the hood of a new Tacoma? All Plastic.

Look at Hyundai, Kia, asian brands sill having issues, Toyota/Lexus have issues, ALL brands have issues. I have owned Toyota's, Honda's, Mitsubishi's and I can go on and on. In our family currently we have VW's, Nissan's, Lexus and Hyundai. Guess which 2 are in the shop right now? The Lexus for VVT-i failure at 80k miles, which put the car into limp mode and luckily there was a wire mesh screen in the system or the metal bits would have contaminated the whole engine requiring a new engine. The other is the Nissan needing a new Blender Door Actuator for the Fresh/Recirculation air for the HVAC system failed at 50k miles requiring the WHOLE DASHBOARD to come out. Lastly our Hyundai is in the shop with 90k miles waiting for a new engine. Our MK7 GTI with 100k miles on it is going strong. So yes, people can have good and bad experiences with ANY brand. So many variables these days, but the problems we have currently with our "Asian" cars were things totally out of our control. Things happen, I don't mock any of the brands and chalk it off as just quality of all cars these days just isn't what it once was. Having to save weight by using plastics to meet performance and fuel economy goals cause allot of these issues, so instead of blaming a brand for this or that, blame the Governments that set the stupid requirements in the first place.
@@eppyz Sad part is when you have to write whole page in order to explain basic staff to some random simpleton from internet. I would add one thing, German cars are way more fun to drive than anything Japanese, so in my opinion, it's worth extra maintenance cost.
Love the video. I had a 2004 Touareg V10 TDI for a few years… until it wiped out a camshaft. Sold it to a TDI mechanic friend who replaced the cams and continues to drive it to this day. I have a few videos of it on my channel. Friggin’ awesome truck.
These kinds of engines were what made VW so cool back in the day! Shame that the innovation and uniqueness has gone away. Sadly, I never actually got to drive one of these. They must have hauled
I'm a happy owner of a 4.2 V8 Touareg, and I love when these kind of engines hand over to someone like you! You know, I hope to see all the engines ever put in Touaregs here, specially the W12 one. Some people will say it's just 2 VR6s coupled together, but I doubt it's that simple.
But it is exactly so. Even BMWs V12 just consisted of 2 compound 2,5L 6-cyl engines. It was a pretty simple, but great engine. I lucky bastard had one for a couple of years in the 90s. It never gave me the slightes issues.
no! your electric car wont be able to do what that diesel actally does! the v10 was a total exageration which they could have took more time to make it simpler instead of couple two 2.5l, engines together.
The amount of “sadness” built up in this engine was insane. Just traded a ‘13 Benz 3.0 diesel, the transmission was shifting rough, a/c wasn’t cooling properly, the car was worth maybe $7-9k even though everything else was okay. Didn’t make sense to spend more than half its value on repairs. Sad to see it go. Replaced it with a Nissan Frontier. Last vehicle I’ll buy, I’m old🫤. Great video!
This is a good example of something that is impossible or impractical to repair. Or both. Although I've thrown away some money in my time, avoiding things like this has allowed me to save for retirement. It does make for a very interesting video, and thank you for putting in the effort to present it!
I appreciate your passion for your work, you make the worst cars to work on look easy. This is such a great example of what vw audi has been doing to drive its reputation into the ground. When you mentioned the juxtaposition of the original beetle and how easy they are to work on compared to this, its so clear theyve lost that value. I am not a big ev fan, but thinking about vw audi and their insanity with designing ICE engines, it would be a significant improvement
I drew the first gear set for the rear of the engine from the VW parts department in South Africa about 10 years ago. Was a nightmare to get everything timed as no shafts have any keyways, they use diamond washers to lock the gears onto its respective shaft. Luckily the dealer had all the special tools you need. The Touareg is still running today 😁😁
Is this the LAST VW engine teardown? HAHA No shot. but boy I hope you guys love this video. the V10 is WILD
this v10 tdi and the v12 tdi from audi are a marvel of engineering everything is robust and made to last quite a long time (idk what happened to this engine in particular)
I’m replacing the head gasket on my Audi B6 3.0 AVK. While it’s a big pain, I’ve actually come to appreciate the design. One timing belt two run all cams (aka 2JZ), modern variable valve timing on both intake and exhaust, 5 valve head still, variable intake runners, no rockers to worry about. Aluminum block with cast iron liners. However, the cooling lines, vacuum lines, PCV and secondary air injection is a rats nest!
At least some of the engineers learned the lesson from the rear timing chain guides on that V8 and switched to gears.
@@300DBenz it’s odd because this was about the same time as those. It seems like it was the last timing belt design, but the description of the engine said the block was derived from the V8. Not sure if that was the older V8s or the B6 S4 V8.
Always wanted to work on/own on of these beastly engines
As an engineering student, I’m in awe.
As a mechanic, I’m terrified.
I'm in the same boat, this is crazy stuff. I can't imagine how long it took to develop this thing
@@benjagt9319 or how long it would take to put it back together ...
you should be terrified as an owner... For mechanics it's just more time and effort while working on that clock (or engine😂)
@@SlavkaZhuravka it is terrifying as a mechanic, if you miss something and it has to come out again you are in deep shit. Not just paid hours you're missing out on, but the schedule for the whole week is f'd.
@Scouter98 Okay, that was a thing, which I wasn't thinking about. As an office rat it was hard for me to imagine exactly that use case. But indeed, once you have forgotten literally anything here below the cable harness, you have to disassemble half of the normal engine
I don’t want a V10 TDI anymore.
😂😂😂
Now youse can't leave.
Just get the V12 TDI 😆😆
i want a v10 tdi even more!!!
@@future62”I will never forget the look on their faces…” 😆
Im literally doing this job at work, had bad O2s, all fuel lines rotted, p/s pump leaks, oil leaks. Have the engine out and almost ready to go back, great timing for this video!
cost for the job/ miles on the engine?
How can that possibly be cost effective for the customer. That car in decent shape isn't worth what it costs for all that work is it?
@@dddon513 Good ones have been going north of 15k for awhile. Pretty sure a low mileage facelifted one sold for almost 40k a couple years ago
@@dddon513 Have you seen the cost of new cars and trucks?
I've done all the work on my 2008 v10 and once you've pulled the engine 2 or 3 times it gets easy/faster and just accept if the engine or anything within 3 feet of the engine needs any work the motor has to come out. It really isn't worth fixing these days but once you drive one when it's perfect it's awesome and towing well it acts like nothing is even behind you. I normally tow somewhere around 18klbs (have towed heavier) my trailer is pretty heavy and with two cars on it doesn't sweat much but you wear through brake pads and rotors fast. One day I'll try and find an upgrade for the brakes that makes sense and won't be gone when I need pads or rotors again. I'm glad whoever is paying you to fix their baby is doing it. These were really built to last they just missed a couple of things. Yes they aren't worth much these days but if you find one that's been well cared for they bring pretty good money. What other VW had orange interior lol thank you for keeping one alive and not sent to the scrap yard. You definitely need to be able to afford of at least make them somewhat cost-affected to keep.
I was the first VW tech to remove this engine on US soil. VW engineers came out to document the job as the VW Elsaweb didn't have service informatiom. Right turbo failed at 17k. Total warranty time was about 30 hours. Took 60 overall with diag included.
omfg hope you were paid hourly for that one
@Poorschedriver no dealer in America pays a tech hourly. I lost horribly on that job. That's why I no longer work flat rate.
@iamtheoffenderofall not entirely true, I know some porsche techs are paid hourly on the West Coast. It's a shame because there is zero incentive to do a job like that.
@Poorschedriver I call bull on that. And for incentive....two choices, do the job or find another job.
@iamtheoffenderofall Porsche master tech Peter Smith stated he is paid salary on the porsche club podcast episode 137.
Fun fact, this engine is basically 2 2.5 Tdi's stuck together, that's why you have so many gear, they're doubled plus the ones to synchronize them, camshafts, heads, injectors are all the same, not sure about head gaskets, the block is where the differences start.
Also let's not forget there is a V12 Tdi from the Q7, that would be nice to see on this channel.
Great job Charles
blok is the only difrent injectors headgasket etc all the same turbo is same size as axe 174 bpc 174 hp engine only diffrent shape cams are the same pistons same
We never got the V12 TDI in the US I am pretty sure, he would need to import
they could have took slightly more time to maybe develop electric driven accessories instead of literally complicate everything. Thats a gigantic pile of mess
@@alanmay7929 the base engine that they derived the V10 from, uses timing gears, so it’s not much they could have done.
The V10 is not a a designed from scratch engine, they just stuck 2 5 cylinder engines together
Isn't the 2.5 TDI like one of the worst engines ever made ? Lmao now imagine 2 of them in a pair in one engine 🤣🤣
As a person that daily drives a 2008 Touareg V10 TDI, you just have to ask yourself “what’s the worst? It’ll blow up” and you’ll never be disappointed (I dropped my motor last weekend)
Pretty much. I have a 2010 in Brisbane and had the motor out for 6 months of last year just doing engine mounts and welding up exhaust manifolds. They are a unique piece of automotive history. Good luck with yours 🤞
@@carnut9193 Neat, I have an 04 in bne. incredible car
Haven’t had to drop the engine on my 07 v10 Touareg yet but man it is a challenge for sure to do anything with the engine in the car recently did the alternator and emissions deletes (egr dpf) thankfully can all be done in the car but man what were they thinking when they put that together 😂 I do love the car and plan on keeping it long term it’s a fun off-roader it’s unusual and it’s rare
You guys spelling it all wrong, its Toerag!
my second year as a tech at a vw dealer back in 07 we had huge storms that year and one of them got hydro locked, touareg got towed in and insurance was paying 37 hours to replace the motor, everyone in the shop was hiding from that job, i ended up doing it took me 5 days to replace the engine, that was the first time working on a v10 tdi and the last time. lol
My girlfriend who has literally zero automotive knowledge is starting to enioy watching some Humblemechanic with me! She's very supportive of a project car idea...all thanks to us binge watching your vids! Long time follower for about 8 years..keep up the great work!
Time to buy her an old Jetta and a toolkit 🤣
I wanted one of these back when still available new from dealer. Now I am glad I kept with my 03 Jetta TDI.
haha the Jetta is a home RUN!
The 1.9tdi is great.
Ive worked on a few of these. Starters are engine out. I can do the passenger side tandem pump im chassis, but the drivers side the engine needs to drop. They aren't very common, and they remind me a lot of the lml duramax to work on, from the standpoint of your order of operations are critical. Putting them back together in the correct order is super time consuming and there isn't enough of them rolling through to develop the muscle memory. Speaking of duramax, the duramax engine uses lots of 14mm
I used to work for Deutz, and their engines are a breeze to work on. They had 3,4 and 6 cylinder versions as well as air cooled and liquid cooled.
Those are from a very different era when German engineering actually commanded respect, super simple and very reliable.
It's a real shame you mostly find those engines running airport equipment, reefer units, generators and some old farm tractors. That's the case at least here in the States.
@@michaelbolton1090you can do the starter in the car but it sure is a pain in the ass you gotta take the passenger side engine mount off and a few other things you’ll be working in a blind hole obviously but it is possible to do it that way it has been documented at this point as well but yes this engine is extremely hard to deal with (I love mine)
Thank you for being our VW lord and guide. I’ve fixed countless problems because of your grace.
Not even ten minutes into this video I already felt compelled to thank you for all the hard work you do to show us all this interesting stuff
A worn camshaft is a result of leaking fuel injectors.
The diesel leaks into the engine oil and the highest sheer wear location suffers first. These are the camshafts and lifters.
Replacing the camshaft and lifters does not fix the problem because the injectors are STILL leaking.
You’ll need 2x new cylinder heads, 2x camshaft and lifter kits and an aftermarket injector bracket kit from Germany to prevent it from happening again. 👍
Awesome engine !!
If a V10 TDI engine can pull a 747, and HM can pull a V10 TDI engine, then by the transitive property of pulling, Charles can pull a 747! Congrats on having, I think, the only V10 TDI teardown video on UA-cam -- Either now, or well into the future. 🏅
Check out the german YT channel FixitAri. He is a pro and recently uploaded 6 videos on removing, repairing and installing a V10 in a VW Phaeton. The V10 is a nightmare. Almost everything is an engine-out job, to include replacement of the starter. Initially, it was designed to be used in the Touareg, but not in the Phaeton. But stubborn Ferdinand Piech insisted that his engineers shoehorned it in, which required a lot of alterations of the engine. It is great, as long a it runs. But beware if something breaks, then your worst nightmares will come true.
One thing that everyone should think about in this scenario:
Imagine if the customer had agreed to do the job at whatever shop diagnosed it. The amount of added parts like that cross over, alternator harness, glow plug harness, etc would have absolutely wrecked this estimate. Plus the likelihood that all those parts are still readily available probably isn’t great. The shop would get the engine apart and possibly not be able to put it back together for months if the parts are available at all.
I had one in a Phaeton. Loved that car. But could not afford to keep running and went past my DIY ability. Just loved it.
thats the biggest issue. Especially now, you can buy them cheap, but youre still fixing a $100k car in 2005 money. $$$$$
@@HumbleMechanichow available are parts for this engine these days? Hard to find, unobtanium or has to come from Germany since no one stocks them? I'm kind of interested in one of these as a project car since they made more of these than Phaeton's.
@LoneWolfSparty last one I did the tandem pump was tricky to find and had to be sourced aftermarket. Everything else, the turbos and manifolds (they crack) were available through vw.
@@LoneWolfSparty At this point, you can still get most of the parts. Most of the Seals are available from VW still and things, that are shared with the 2.5 TDI are also easy to get aftermarket. It's the V10 specific stuff, that can be hard to get, especially after VW stops selling it.
@@janniss6401 Poland and eastern Europe for parts.
I have an '04 V10 with 596k km on it, It's my absolute most favorite vehicle to drive, but there's a reason I have a second one sitting around as a parts car... Had to do most of this fun work on the top side to get the alternator out to be rebuilt and fix the oil leak from the pressure sensor that was flooding the valley (probably also why the alternator died). cylinder 5 glow plug is bad and I'm not willing to try and get it out to have it break, when it starts fine with 9 others.
Removing the alternator is quite a job. It only just comes out!
I see a new humble mechanic video and I watch and like it
THANK YOU!!!

BETTER THAN NETFLIX
Here too, in France when you talk with some car enthuisiasts even if they are not VagFans we all remember this GOLDEN ERA of VAG around 2000s - 2012s : V5, V6 TDI, V10 TDI, V12 TDI , w8, w16... Audi r10 at LeMans 2006 with the V12 TDI. now everything is "e".
Find a V12 TDI too please !!
As someone who got out of VW's when they got radiators... that thing is nuts..... You should do an air cooled motor as a short.
That would be a short video - such a basic engine by comparison
As a guy, who loves diesels and especially Pumpe-Düse diesels, this is my all-time favorite engine. To me, it's an engineering masterpiece, especially when this thing is sitting inside the engine bay of a Phaeton. Physics kind of dictates that they aren't easy to service... But here in Europe you see a lot of these engines in cars with 250k + miles for sale, where it's very apparent, that they were run on a repair budget of basically 0.
They can afford car's price plus interest, but not repairing it :/
I've replaced the cams in a number of these and can replace them without pulling the engine. Though it is NOT a fun job. You can delete the EGR setup.
I also modified the turbos on one for a larger downpipes. We were able to get it up to 12 PSI after. Very fun unit to drive.
Part of the reason why the camshafts wear has to do with the way the cams are ground. If you replace with a true hydraulic grind camshaft from Colt Cams and put in new lifters (if using the black nitrided lifters remove the 1 spring which gives a valve lash).
We want a 4.2 with chains next I speak for the people
4.2 Chain engine, added to the list. But you may have to rally the people.
im here for it!! i LOVE those 4.2 V8s
If you mean Audi's v8 engine with rear timing. It's not that complicated, i have done few. If not that then don't know.
@@carsandgaming991sure it’s not as complicated as this but I’d still like to see a teardown
@@devinf49 yeah no worries 👍 my point just was that it isn't as bad job as many people say. Ngl i would enjoy watching that teardown too 😅
Fun fact: the reason why V10 TDIs go down and wear through camshafts has been blamed on the type of oil that people would mistakenly put into these engines. Like Charles said, these are PumpeDüesse (close enough) they are somewhat different and If i recall V10 TDIs require VW 507 oil, people would put regular 502 or 504 and it wears the cams. If you use the correct oil V10 TDI will run to 400k miles easily. As long as you replace the turbos at least once.
Actually the oil that VW calls for doesn't have enough anti wear additives. If you run a regular synthetic diesel oil like Rotella T6, they don't have the issue. Same with the other Pumpe Duse engines.
Agree. use t5 15/40 high zinc with 5k oil and filter, Engine idles like a sowing machine.
504.01 was specially developed for the pumpeduse engines, When they switched to 5w30 (505.01) with long life intervals all the misery began.
@@thijs_rallye8621 No, all wrong. 504.01 does not exist.Special oil for this engine was 506.01 (0w-30 ACEA C5), other PD engines had to use 505.01 5w-40 (specificaly for PDs). Both of them later "superseeded" by 507.00 5w-30 or 0w-30.
From my opinion 506.01 engine oil was introduced because of better lubricating in cold starts etc. providing more protection of the alusil (nikasil) cylinders when oil was cold. This thinner oil then resulted in less "pressure resistance" on the cam lobes. Otherwise I can't answer the question why R5 (2.5 TDI PD) and V10 (5.0 PD) are way more susceptible to camshaft wear compared to other PDs (1.9 and 1.4) that can easily go almost double the kilometers to the same camshaft wear...
@@vasek987 You are absolutely right, I mixed things up, I meant 5w40 505.01, which wsa superseded 5w30LL as you say. As for the wearing, from what I've understood is lugging the engine doesn't help the cam wear. I can imagine an engine with more cubic capacity will be lugged harder than a small capacity engine.
Even if I had the experience of a master mechanic, I would open up that engine bay and just go “NOPE”. This one looks like as much labor as a hyper-car.
Hey Charles, this is precisely why I tune in to your channel, as well as Paul’s. You both have a profound appreciation for the intricacies of human engineering, especially when it pertains to engines. I once shared my thoughts on VWvortex, but after facing a barrage of trolling, I decided to respond to them. Unfortunately, that led to my ban from the site for criticizing electric vehicles and highlighting our current consumption of precious metals, leaving little for the engineers of the future.
Hi Charles.
I feel conflicted when I watch your videos, like this one. You do sound like a ‘humble mechanic’ but you clearly have the big brain of a highly intelligent engineer! I’m sure in another life you would be designing these amazingly complex machines instead of maintaining them, assuming this isn’t the case already! As a fellow engineer I thoroughly enjoy your videos and truly appreciate the hard work and effort that goes into making them. I also think VW should give you some type of award for displaying the engineering that goes into their vehicles. As you explained, even this incredibly (and perhaps, unnecessarily) complex engine demonstrates some impressive engineering.
0:47 - 0:51 Already contemplating your life decisions? Thank you so much for all that hard work and all the hard work you are still going to put into this! That was super cool!
Charles this was such a cool video, thank you for going through the trouble to share this with us. This one really hits home for me - my VW love all started with the 1.9 TDI (a PD!), my first car... I didn't know ANYTHING about cars before I got t, and as luck would have it, that first car had a bad cam in it, JUST like this one (well, caught it a little earlier, phew). I learned so much not just about cars but specifically about early 2000s VWs, and went from never having done an oil change to having replaced the cam and lifters and re-timed the motor myself. That's about when I found your channel, and there is so much I would not have done right were it not for your content.....and the rest is history. Thank you for continuing to keep the VW love alive, always stoked for your next videos and whatever you're up to. Thank you Charles!!!!
Was torn between this and the 3.0 v6 tdi when picking a Touareg back in 2018. Liked the idea of having a v10, but decided it was a bit more practical to go with the v6. I have been in love with it ever since and this video just made me love it more lmao.
This engine was an engineering marvel. Never want to work on one, but it was a truly incredibly successful in motor racing. This V10 and the V12 TDI were so dominant while racing in the LMP1 series (R15 and R18). Very interesting to see one taken apart!
I have two of these, an 04 and an 06. Yes, i'm a glutton for punishment. I just finished replacing the cams and lifters on my 06. For those considering camshaft repair; This job can be done in situ. Place the front end in service mode, remove the false firewall and use a small pulley remover/installer tool. BTW that stupid coolant junction is almost impossible to remove without breaking.
It appears the camshaft issue is likely due to the tandem pumps leaking diesel into the crankcase....
It looks like the lifters are supposed to rotate, is that right?
The reason I ask is if they are, that one he showed that was bad looks like it stopped rotating and got excessive wear in one location.
@@jameshaulenbeek5931 Yes, I believe they are designed to rotate,.
.
Mine didn’t have tandem leaks and they were worn at 105k miles, exhaust way worse then intakes. I’m now at 210k with colts so I’m curious about doing an inspection on them.
@@Italmind heh... diesel is always looking for a way out!
@@JoshsJettas Yeah, the Colt guys are pretty sure it's bad OEM cam profiling. I have also noticed it tends to be the exhaust side that wears. Perhaps it's not fuel leaking past the pumps.
Thanks!
🥳
Vag even did a V12 tdi. Probably kinda like two 3.0 tdis in a row. This V10 here shares a lot with the 2.5 inline 5 tdi.
its almoste the same injectors cams turbos etc are the same
Might be 10 years too late but finally someone makes a video on them.
6:04 "Old air-cooled beetles are probably the most serviceable engine ever made. Compare that to this; the least serviceable engine ever made." And people wonder why VW is circling the drain.
Thanks for the video Charles - your teardowns are always a treat!
If you were dumb enough to buy this, you're smart enough to now go buy something.... anything.... better. Maybe a Veyron?
If you tried to building a motor with the reliable power this thing has, and have every chain and cog and plug and spinning shaft readily accessible, it would unfold and sprawl out across a 10' x 10' room. The smaller things get, the simpler they and the less power they make, until you start getting into cutting edge material technology.
"VW is circling the drain", you mean second most sold vehicles in entire world, that VW??
@@senco981 Yes, VW currently is in dire straits. Mainly because of quality issues.
@@guzziwheeler All big car world manufacturers are, google it. Global economic crises and China's industry picking it up make cars hard to sell these days.
That thermostat brings back memories. Bought one of these back around 2008 at auction in Florida while visiting my mother. Had over 120,000 miles but looked great. Went to drive it the hour or so back to her house. Ran fine the first 5 miles on the way to the highway, then once ON the highway, the temperature gauge starting rising. Eventually the overheating light came on so I pulled over and had it towed the rest of the way back. Turns out the fancy electronic thermostat was bad and stayed closed all the time. Not having any tools with me there, and not wanting to dump $1,000 in a thermostat job at a VW dealer there, I figured that if I kept the speed at 50 mph, the temperature stayed just above the middle mark on the gauge and I could theoretically drive it 1,000 miles home like that. So that's what I did a few days later. 50 mph at about 1,200 rpm for over 22 hours and probably P.O.ing a lot of drivers behind me on I95. The only good thing is I was getting over 30 mpg in a heavy V10 diesel. That must be a record.
Honey wake up a new humble mechanic video is out
2004-5 was probably the coolest year for all the cars. Each model had something crazy going on and the flagships were insane. this was a very in depth look at a VERY technical engine. glad we got to see 2 Charles' at the same time!
As a dad, I appreciated the “off the table/ on the table” joke 😂
hahha Dad Jokes are LIFE!
I knew you were going for the joke "on the table, off the table" and I genuinely laughed lmao. You do an awesome job talking while you're working. It's interesting because you're enjoying yourself.
Love your videos! I just bought a 22’ Mk8 GTI S DSG with 32k miles (got it for $22k 😀) the muffler was deleted but I have the original muffler. Is a muffler delete potentially damaging to the vehicle or is it okay? Should I get it put back on? Get it tuned?
The dsg is a pain in the ass it's likely to breakdown service it every 50tkm and it doesn't like stop and go but it's still a great transmission fast gear shifts
A muffler delete hasn't many bad things Potential for Reduced Back Pressure
While some performance gains may be seen excessive removal of back pressure can negatively affect engine performance in certain vehicles
And you lose your warranty at least in German
I mean 50t Km not miles I am not into freedom junits I think it's like 25k miles
Iam currently a new-ish VW tech at my local dealership, I've been there for a year Ina half now and Iam honestly really enjoying it! I've been getting told recently how much of a nightmare the Touareg is to work on, and no matter what is wrong with it, it's always such a pain......now I understand lol. I love your vids can't wait to see more.
As a tdi guy, for me this is the crown jewel of diesel engines. Yes, it's complicated, hard to work on. Some consider a $ pit, but the potential if given for these beasts is nothing short of badass! The exhaust note with a decent pipe setup is crazy cool! Loved these diesels when they 1st came out and still do. Thanks for this video! Well done 👏
That's insanity!!! I love the v10 tdi and always thought someday I'd pick one up. After watching this video, not a chance!!! I thought bmw engines were complicated! At the same time, like you said, you cant help but admire the engineering to make it all work! I bet they got all done designing it and one guy was like, "wait... where's the alternator?" And the other guy said "Oh....crap." Very creative design thats for sure!
That whole 'early 2000's' era of VW's was awesome. I thought the V10 TDI was an amazing engine, but now I look at it and think it's just overengineered with a bunch of parts that are designed to fail. I had a 2001 Golf TDI 1.9L that went 400K miles before I sold it, and that thing had never had the engine apart at all. It doesn't look like the V10 had that kind of longevity.
It does easily. Do the known work before it all breaks and you'll find a lot of them in cheap Touaregs here in Germany with up to 500.000km. Normally our cars go to the east of Europe at 300.000km
But.... To do the necessary work, the engine has to come out at one point or another...
That is a really poor argument to make imho.
A well designed engine needs basic maintenance that can be done WITHOUT having to pull it out and spend days faffing about. The V10TDI is NOT well designed.
If money and time are of no concern LITERALLY EVERY SINGLE ENGINE EVER BUILT could run fro a million km and more. Just rebuild it here and there, boom, you keep going. It's that easy ;)
@@leviathan5207 Pretty obsolete point, right? A rebuild is not the engine running long. If a non rebuilt V10 lasts 500.000km but Cummins and Powerstrokes die left and right, I choose the more complex engine.
And if you say basic maintenance, the V10 NEVER has to come out to do BASIC maintenance. Why would you? No timing chain or belt, so your basic maintenance is reduced to oil, water, brake fluid, all filters, every four intervals the rubber coupling of the alternator for which the engine does not has to come out and if you do PD-injectors at 500.000km when they first fail, the engine stays in as well. I cleaned all injectors preventatively at 230.000km while cleaning the intake and doing both took me 12 hours. Alternator took me 2 hours. Thermostat 1 hour, turbocharger actuators took me 3 hours per side with the engine in. And none of that is basic maintenance.
This is an insanely complex engine and it's shoe horned in there, but it's by no means a bad design. Not at all. Considering it has the engine bay volume of your average US car glovebox, it's surprising it does not die the heat death earlier. You could fit two V10s in a Dodge Ram engine bay. If you were to fit only one, you also would never have to drop the engine. So your argument is moot.

Seeing this video, reading your arguments and owning two 1.9 PD, I will agree in your conclusion! This sounds like a bullet proof engine! Seeing those timing gears, no additional service needed!
@@tommelomme6761 I wouldn't go so far as to say it's bullet proof. Since it's an aluminium engine it's a little more sensitive to bad fuel and heat. The classical PD engines are almost always iron blocks and either iron or aluminium heads. Much more heat tolerant and although an AluSil cylinder surface is much harder than any aluminium or steel one, they still can get scored. So you really need to treat the V10 like the engine it is, a rather highly developed luxury engine which saw only use in two cars.
Do the fuel filters, do the upgraded PD holders and avoid high heat input. There is no room for the heat to go in this engine bay. That's the reason for the oil leaks for example. Local heat hotspots are also the problem for the tandem pump which bends and then starts to leak. Only changing the gasket doesn't work for long. Heat also kills the turbo actuators. The turbos themselves fail rather seldomly, but the actuators do because of heat. This engine would be double or triple as reliable if put into a giant engine bay of an American car.
And last but not least, don't by the DPF and EGR cooler version, meaning the BLE. There is so much heat in the V thanks to this fucking EGR bullshit, it's insane.
Just wanted to say this is such a cool video! If nothing else VW can be appreciated for its eccentricity and it seems that you appreciate that too. You seem to be right in your element here, having a positive attitude and laughing things off when many of us would be tearing our hair out and inventing new four-letter words. Awesome!
I am assembling one of these engine's right now. What a delight!
I pray for your sake, you do everything perfectly. Good luck!!!!
I like working on mine too. It takes me 30min to get out both intakes and the fuel rails. Had to do it 6 times to get the rails to not leak after taking them out the first time. The o-rings, which you can't get anymore, never really sealed so it took a while to get the perfect ones. I do everything without power tools. Always with hand.
Oh yes, I haven't fitted the fuel rails or intake manifolds yet. Tomorrow's job.
Ive done a few of these. Starters are engine out, drivers tandem pump is engine out, turbos and manifolds are engine out. Even the upper 02 sensor is engine out. I think typically the repair bills are anywhere from 8-12k. They are super cool though! Sometimes vehicles dont make financial sense (most VAG stuff) but we like the punishment. Also duramax uses a lot of 14mm, and bedplates and gears are super common on diesels, it gives them a ton of strength. The big advantage of diesels is the strength of the engine, its like buying a built race motor because they run all the boost at super high compression.
Welcome Back! Been missing some TDI content
I own a v10 tdi Touareg and work on it my self tbh I find the challenge fun the parts aren’t too too bad for what it is it’s the labor that’s nuts it obviously isn’t my only vehicle so when it does need work I just wait until I have the time and fix it I wouldn’t want to own one of these as my only vehicle for sure
As soon as that back side came apart, i thought "holy shit, it gets worse." Might be one of the most overlly complicated engines ever.
This was so cool,i would never cover those beautiful valve covers with composite but i see what they did,there is a space between them. How everything is layered on the block holy smokes that thing has never breathed,its so complicated its outta my league..
.
the timing area looked like a clockwork, cool stuff!
Recently bought a used EGR Cooler, cleaned it as thoroughly as I could and had it installed in place of my “insufficient flow” in my 2.0
235,000km and the only non fully blocked holes have pin prick sized holes. I’m convinced whoever designed it decided it would be a point of failure and would create more car sales…. Runs great now… plan to sell the one taken out once cleaned, since the labour to replace it in a 2012Tiguan with AWD in very very costly… 7 hours labour…
Delete it
Hello! I'm a simple guy ,I see Humble Mechanic, I say "Hello".
17:20 the real reason for adding turbos is because diesel emission requirements forced manufacturers to lower compression.
The entire benefit of a diesel engine is being able to run a very high compression ratio. By lowering the static compression ratio, you lose power and torque output but you can improve NOx and run a smaller camshaft for improved low end power (swirl flaps are even used now for better low speed combustion).
Also, Diesel fuel actually takes longer than gasoline to burn. This makes designing a high speed diesel more difficult. You can play around with fuel timing but this also increases cylinder pressures. So adding a turbo allows you to force more air into an engine than it normally would do so at 1 atmosphere. You can get better power from the mid range and higher
I was stunned you said only $10K to get the engine running again... I'd spend that in a heartbeat for that beast. I've spent way more than that on keeping my Range Rover running... and now it's dead again 😀
You can get one for less than 10 k that’s a solid vehicle. Which would have been a better play than trying to bring this one back.
@@HumbleMechanic I get it, however at this point don't you think it would be prudent for any V10 to have it's whole intake/exhaust/fuel system to be fully cleaned/replaced anyway? If it were my car, I'd rather bet the $10K on something I know rather than someone else's possible 30sec from disaster car. I've probably dumped ? 2x the "worth" of my RR into it... because I know it. I'm up to $3K in parts this last summer on the V8 4Runner because I know the car... I don'y fully buy into the you can just get a "good" used one for the cost of fixing this one.
@@HumbleMechanic Damn cars are cheap down south! Up here in Canada a solid V10 touareg is atleast 20kCAD, then again we in Quebec love VW TDIs
One day I'll buy Touareg with V10 TDI. I know it may be complicated engine to work on but its classic these days.
I fondly remember the advert with the Toureg pulling that airplane.
... something you'll never need to do.
With an engine you'll never want to own. ugh.
@timewa851 okay?
Maybe it was this exakt car....
Perfect timing, I have one coming in, in a few days for an oil leak in the valley, now I can show him why the bill is gonna ruin Christmas.
Ferdinand Piech was a monster....
Great video as always!
Would like to point out that diesels dont use throttle bodies/valves. They are called ASV (anti shrudder valve) and it has totally different function then throttle valve. it is an on/off valve. it opens when you start the car and closed at shutdown (for smoother shutdown) and as protection for runaway diesel.
Diesels do use throttles. Maybe they didn't back in the noughties but they do now, for throttling down intake airflow. Anti-shudder valves are probably just on/off while throttle valves can be controlled 0-100%.
Immediately after you removed the rear cover at 20:27 that Lionsgate move intro theme with the clock and gears started playing in my head haha 😆
Super cool video!
It's wild to see all the crazy engineering that went into packaging all of that together.
The gear drive end reminds me a lot of the locomotive engines I work on, but with those there's a massive set of gears on both ends - crank, cams, turbo clutch, oil pumps, water pumps, engine overspeed...
I actually love the gear timing... it will likely never go out of time.
Thanks been hanging for a V10TDI tear down, absolute amazing engine, as an engineer I'm in awe. had my 2004 V10 for 10 years and had over 300000km on the clock, sadly it was the failed electrical insulation which did me in. I'd bet that the cams failed because somebody used the wrong oil, VW506.01 only in these things.
Mechanic: This is what fun is made of.
Owner: This is what nightmare is made of.
This video made me feel better about my Maserati 3200gt engine. And it's on jackstands for 3 years
That thing is a nightmare. I can’t imagine the cost to replace an alternator or an AC compressor. There is not one thing on that motor that is wallet, friendly.
You putting a lot of gems out sire and the time and effort to do something like this deserves a superthanks The Wiring KT video you did was my favorite until this one. Big ups to you
I can't wait to watch the "Rebuilding" part of this "teardown"........ hehehehe
Wow, I really appreciate this teardown video. Volkswagen has always been the company of how technically difficult can we do this job? I've had a few from a beetle to a Dasher, to my B5 wagon, and my 2012 Passat. The 2012 has a 2.5 5 cylinder and that's pretty cool.
Interesting how my Dads 1960 VW Beetle that has been in the family since new with over 1 million miles on it, has only had the engine out to install a new clutch and new push rod tubes is still going strong whereas newer VW's like this one is falling apart after only 200k miles? Then VW wonders why Honda and Toyota outsell them 20 to 1. Sad truth, because I like VW's but I understand why people shy away from them too.
"Then VW wonders why Honda and Toyota outsell them 20 to 1." In the USA perhaps, but globally the VW Group of brands sell very well! Toyota Group is the global number one, VW Group global number two. But very interestingly Toyota Group (Toyota + Lexus) is only in 5th-6th position for auto sales in Europe, much lower than their number one position nearly everywhere else.
@@TassieLorenzo yeah here in the USA VW sales are so low I'm surprised they still sell cars here. For example last year in the USA VW sold around 8000 Golfs (we only get the GTI/R) compared to over 300,000 Toyota Corollas. VW has a poor reputation for reliability here which really hurts the brand.
@@eppyz the plastic. Everywhere. The most hilarious usage is in the oil breather system on turbo engines. People stomp on the gas, eventually the plastic cracks, engine light/misfires.
Should've used metal where it mattered. But they build now so you're getting a new car every six-seven years. Thankfully the Asian builders think otherwise.
@@timewa851 Well I would agree to disagree with you. Your implying that ONLY VW uses plastic bits and cheapened their cars and what not. Well, EVERY car manufacturers has done the same, even Toyota and others. Have you seen under the hood of a new Tacoma? All Plastic. Under the hood of a new Tundra? all Plastic, under the hood of a new Camry? Its all the same. The difference is not so vast as you think. Look at Hyundai, Kia, asian brands sill having issues, Toyota/Lexus have issues, ALL brands have issues. I have owned Toyota's, Honda's, Mitsubishi's and I can go on and on. In our family currently we have VW's, Nissan's, Lexus and Hyundai. Guess which 2 are in the shop right now? The Lexus for VVT-i failure at 80k miles, which put the car into limp mode and luckily there was a wire mesh screen in the system or the metal bits would have contaminated the whole engine requiring a new engine. The other is the Nissan needing a new Blender Door Actuator for the Fresh/Recirculation air for the HVAC system failed at 50k miles requiring the WHOLE DASHBOARD to come out. Lastly our Hyundai is in the shop with 90k miles waiting for a new engine. Our MK7 GTI with 100k miles on it is going strong. So yes, people can have good and bad experiences with ANY brand. So many variables these days, but the problems we have currently with our "Asian" cars were things totally out of our control. Things happen, I don't mock any of the brands and chalk it off as just quality of all cars these days just isn't what it once was. Having to save weight by using plastics to meet performance and fuel economy goals cause allot of these issues, so instead of blaming a brand for this or that, blame the Governments that set the stupid requirements in the first place.
@@eppyz Sad part is when you have to write whole page in order to explain basic staff to some random simpleton from internet.
I would add one thing, German cars are way more fun to drive than anything Japanese, so in my opinion, it's worth extra maintenance cost.
Supposedly, the balancing weights are kind of exotic. Check with your local metal recycler what they pay for tungsten alloy. Not negligible amount.
I work at a shop that somewhat specializes on euros and now I know that I will refuse to work on this engine if it ever comes in
I can watch engine and transmission teardowns everyday! That's some amazing work.
Good news ma’am it’s just your starter. Bad news is the entire car needs replaced.
This guy is good. Knowledgeable and entertaining. I don’t know how he doesn’t get beard tied up in everything. Genius!
Please do a VR5
yes!
Please include a timing chain replacement video, cause mine are done... again :(
Told myself I wasn't going to watch someone tear down this basket case of an engine again, but I couldn't resist. Good stuff 👌🏾
You should fix it and give it life again I'd love to see it
sadly the car wrapped around it would have taken so much money to get it proper right.
@@HumbleMechanic remanufature and sell? Plenty of Touaregs crazies out there. Dont forget to sign your name to the engine!
Love the video. I had a 2004 Touareg V10 TDI for a few years… until it wiped out a camshaft. Sold it to a TDI mechanic friend who replaced the cams and continues to drive it to this day. I have a few videos of it on my channel. Friggin’ awesome truck.
Im very suprised how eazy it was to take out glowplugs.(thats only thing i hate more then losing 10mm)
Awesome, Charles! The illustrations imposed? During this genius! Thanks again, Sir.
These kinds of engines were what made VW so cool back in the day! Shame that the innovation and uniqueness has gone away. Sadly, I never actually got to drive one of these. They must have hauled
I'm a happy owner of a 4.2 V8 Touareg, and I love when these kind of engines hand over to someone like you! You know, I hope to see all the engines ever put in Touaregs here, specially the W12 one. Some people will say it's just 2 VR6s coupled together, but I doubt it's that simple.
But it is exactly so. Even BMWs V12 just consisted of 2 compound 2,5L 6-cyl engines. It was a pretty simple, but great engine. I lucky bastard had one for a couple of years in the 90s. It never gave me the slightes issues.
This channel is by far the best commercial for why to get an electric car.
no! your electric car wont be able to do what that diesel actally does! the v10 was a total exageration which they could have took more time to make it simpler instead of couple two 2.5l, engines together.
currently trying to make my W8 passat road legal but having issues with some lambda sensors, great video as always
I wonder why VW group is close to going out of business 😂😂😂
oh this was PRIME TIME for VW. Now it's all dodgy 2.0 turbos.
@@HumbleMechanic yes Charles, everything is going high pressure turbos which pushed me to go Tesla. 😩
The amount of “sadness” built up in this engine was insane. Just traded a ‘13 Benz 3.0 diesel, the transmission was shifting rough, a/c wasn’t cooling properly, the car was worth maybe $7-9k even though everything else was okay. Didn’t make sense to spend more than half its value on repairs. Sad to see it go. Replaced it with a Nissan Frontier. Last vehicle I’ll buy, I’m old🫤. Great video!
That timing setup is some crazy steampunk engineering 😮
Such a cool teardown. You’d have to really hate yourself to put it back together tho…
This is a good example of something that is impossible or impractical to repair. Or both. Although I've thrown away some money in my time, avoiding things like this has allowed me to save for retirement. It does make for a very interesting video, and thank you for putting in the effort to present it!
33:26 they're clocked like that so the rods can fin through the bore with such a large bearing diameter, very common on larger than car deisels
I appreciate your passion for your work, you make the worst cars to work on look easy. This is such a great example of what vw audi has been doing to drive its reputation into the ground. When you mentioned the juxtaposition of the original beetle and how easy they are to work on compared to this, its so clear theyve lost that value. I am not a big ev fan, but thinking about vw audi and their insanity with designing ICE engines, it would be a significant improvement
That V10 diesel is actually pretty dope. Anything gear driven is nice. 30:52 is my favorite part of this engine. That front cover is crazy cool.
That rear gear drive mechanism is awesome. Way better design than the garbage belts that are used for everything.
Even the common 2.0L turbo EA888 is not spared from timing chain stretch. VW is just better with old timing gears.
Ok that was master level tear down. Cool but complex but cool, indeed.
I drew the first gear set for the rear of the engine from the VW parts department in South Africa about 10 years ago. Was a nightmare to get everything timed as no shafts have any keyways, they use diamond washers to lock the gears onto its respective shaft. Luckily the dealer had all the special tools you need. The Touareg is still running today 😁😁
