"I’m totally blown away by the enormous complexity of this engine" - this comment merely exposes your ignorance of modern engines. This level of complexity is common across manufacturers in their advanced engines. Indeed, there are several levels of complexity beyond this too

This 2.9 tfsi and the 3.0 tdi out of the s4 s5 s6 have major problems with conecting rods bearings i work at audi in germany and this a 'Normal' Problem in the s4 s5 s6 rs4 and rs5

Likely the tune made the engine run much hotter than the OEM cooling can deal with causing lubrication and cooling failure. These engines already run hot with the OEM tune. You definitely need upgraded cooling for any stage 1+ tune to retain some reliability.

No, it's a known failure point, Audi fixed it at 06/2018.
Water meth is the answer, makes the engine run a lot cooler. Also the cats being in the engine bay create too much heat so go catless and ceramic coat them. Bigger Wagner charge cooler is a must.
You have a good channel and come across as very professional and honest guys. IMO these German cars are vastly over complicated and unreliable. I wouldn't own anything like this but if I did it would not get remapped and would be well cared for. You're doing a great public service making Audi victims aware of how deep the water can be. Thank you.
Audi victims are in deep water when selling or maintaining. So unless they lease and turn in they will be going broke trying to keep these cars for more than 100k.
Those rocker arms are notorious to fail at 30K miles or so on these Porsche designed V6s. Water pumps are also pushing coolant out into the vacuum port also, causing overheat and low boost concerns if it gets past the coolant solenoid and into the N75 solenoid and vacuum reservoir. Good times, lol

Nice video, a nice reminder again, why these new audi engines/cars are only good for lease and before the warrant expires, let them go... PS: One of the best audi engine is the old 5 cylinder.
Super impressed by the diagnostic! If I ever move to England I know where to service my Audis. But the thing that raised my eyebrows the most is the case of insurance or lack of insurance. In Sweden owning such a expensive car you would have a insurance that covers a blown engine. 5 years (80.000km) or extended (8yrs 100.000) and it would cost between 150-300 quid for owner too have the engine replacement 🤷♂️
Very interesting video. Completely cures me of any urge to own one. Two major failures. Parts unnecessarily expensive, especially the charge cooler which really ought to be warranty or at least some "goodwill". Very much like older Audis having owned a B2 & B3 90s and still own a C4 A6 with the inline 2.5 diesel. 26 years and over 340k which just service parts. Never had a warning light on...... Working on a friends B6 A4 with the 2.5 V6 TDI which had suffered from the cam lobes shifting around breaking a couple of rockers we realised that it almost has more parts in one cylinder head than the whole of my inline 5 cylinder engine..... Is this really progress?
Not that it matters that much but it’s a 2017 car, as commented below. Great videos. In the previous one I thought typical dealers re:replace engine. But now you kind of can see why as they look for simpler solution and wouldn’t be willing to allocate the diagnosis time as much as you guys. If I had an Audi I’d bring it to you guys! :)

I've got 2x of these engines 🥲 '18 Audi RS4 w/no issues, one turbo waste-gate was jammed open, all good otherwise. '18 Porsche Cayenne S bought from auction & intake is full of milkshake from LHS turbo inlet PCV hose & manifolds are full. Compression test 210,245,230,225,205,180. Cyl6 slightly lower. Coolant not mixing, no oil all clean. Oil is milkshake though. Engine turns by hand. Might smoke test cylinders next? Hard work to pull engine/trans out & check internals without a hoist. I wish u guys were in Australia 🤕keep up the good work 😎
@@VAGTechnic Thx for reply but Cayenne is air to air intercooler. Was bought from insurance company, I’m thinking last owner poured water into the oil. Filler is next to oil/water separator & PCV connection. Cylinder leak down test was perfect too. Will throw in new plugs & cycle some oil thru it & hope it starts 🤞
Firstly, top video, excellent diagnosis I’d definitely come to you guys in a heartbeat with my car! Secondly, I was in the process of buying one of these but paused due to several factors. That pause allowed my wife some time and as a result we bought a new horsebox, seriously expensive thing with very costly maintenance I constantly complain about! That said, it’s now looking cheap compared to running and maintaining one of these! Feel like I’ve dodged a bullet, won’t now be getting a B9 S4, certainly not one with any sort of mileage on!
Very Good Video! Always love to watch :) In my Shop we also had a Rs5 with less Milage and we had the exact same issue, but due the car was new back then and it was still in warrenty we were looking way longer then you Guys did! Well done
Thanks , we actually spent two days making it run , than once the engine is out it was matter of time to find it 😄 it is sad what happened, I thought when I saw the 2.9 first I was like woooow , good platform , few years later I come to decision I have to put my B5 S4 back on the road , no chance I’m getting 50k car and facing these issues
It was looking promising at the start of the first video ,,, but its gone downhill somewhat since then. But well done , just one of those things I guess , my old 2.5 diesel allroad did something similar when the cam lobes wore , the followers just fell off a few valves and into the head luckily a set of cams and followers sorted it out.
Really interesting to watch. My B9 S5 currently has its engine out at a local garage as there isn’t any compression in one cylinder. Garage suspect its due to rocker arm issues 🤦🏻♂️ Audi main dealer say they do not seen regular issues on these engines!! Really keen to see how this all ends up as you are further ahead on this car than they are on mine - hopefully I won’t have the other issues that plague the 2.9 though???
@@privatprivat5431 did you fix and keep the car or sell on in fear it would happen again? Found out now mine has damaged the crankshaft and cylinder head!!
@@Ben-hk9hc No, it is in the workshop at the moment and the engine has yet to be removed. I had shavings in the oil, which would mean my entire engine was gone. Was your car stock? What are you doing now?
Keep up with the good work buddy, I can tell you as an Audi technician that all the new models are plagued with problems 😂. Byw stay away from the Q8. . In my personal opinion ppl just pay high prices for a product that is not worth the money.
Rs3 ftw… Strong motors, make good power , reliable, and in terms of vag they’re not the worst thing to work on.. I think the driveshaft being frail af is stupid but aside from that not too bad… I was jdm back in the day, but the interiors just aren’t up to snuff I guess you’d say. It like you want to have a nicely modified fast car but need a nice interior for the adult side ..lol🤣🤣 basically need to make enough money to not care about cost or make some sacrifices when choosing a vehicle you intend to modify🤷🏼♂️. Great channel, great info 🤜🏻🤛🏻
I have a 2010 A5 ..apr_stage2 , and good bit of other mods.. and a 2014 Q7 prestige also modified. ( but not many tuning options in the 4L ) so just racechip tuning box and throttle controller along with other mods. Luckily no issues with either but want to upgrade mine and only real option is the rs3 basically too scared to get anything s5 and up . 1 can’t afford it brand new so it’d be used and 2nd it won’t be staying stock. 🤷🏼♂️
Thank you for your vlogs! The vlogs are very nice to watch and nice editing skills. You guys have an very sweet workshop and very nice cars. Keep up the good work and looking forward to your news vlogs. Kind regards Geert, Amsterdam, the Netherlands
I thought my BMW M62tu V8 was complicated. This Audi V6 makes that motor look like a lawn mower engine. That said I'm glad technicians like this exist.
I would not in a million years buy a car with this engine. Or any brand new car. It's not only the complexity and unnecessary over engineering that appals me. It's the insane amount of work you have to do to maintain or repair these.You can't reach anything without removing the engine. The keeping cost is insane I think 😂 I completely agree with what he said in the video, 2.7TT is an amazing engine. Simple yet powerful. Also the 1.8T is still a phenomenal engine.
Yeah absolutely all car companies should be made to produce an engine and transmission that will last at least 500,000km with nothing more than simple servicing and if not they should be made to fix at they’re own cost.
Coming from an LS guy with notorious rocker arm needle bearing failure, hopefully you find all the needles before reassembly. In the American Engineered(haha) LS those needles work their way down to the oil pan, eventually getting sucked into the oil pump and wreak even more havoc than the part actually failing.
What an absolute nightmare. So complicated, I’d be shitting myself every time I’d drive an Audi v6s or v8🤯. Maintenance must be more expensive than maintaining the wife and kids🤪
Great service! Great evidence of technical knowledge! I'm surprised Audi doesn't pay UA-cam to censor your channel, because for a car of this age and mileage to have such a catastrophic failure screams protentional buyers to runaway from this brand! I never seen so many timing issues documented on one brand regardless of the engine. Awful!
And on top of that they put the timing chains at the rear of the engine so they cannot be easily accessed. They went out of their way to engineer it poorly !!!
Dude loving the content keeping it real!! As always you make it look so easy, and what’s your secret you still look fresh as a daisy at 10pm I’d be knackered 😂😂😂🤘🏾🤘🏾🤘🏾👏🏾👏🏾👏🏾🙌🏾🙌🏾🙌🏾
Wrong oil caused rockers to seize? Coolant contaminated oil? In any event, whoever was servicing this vehicle didn't check for known issues like the intercooler failing, leading to the failure of the rockers. Not sure if it was a contributory factor, but the hot V turbo location does generate a lot of heat where nobody wants it.
With all the sensors on that motor seems like a code would be thrown if it had that much water going through it and if not, they got a sensor for everything else but you got coolant going through the intercooler and no way to tell it's gone bad?
If a recall correctly from the earlier video you were getting timing error messages, I,guess that’s not so surprising now. If it had been me I would have wanted to take these heads of first and put a scope down to look around and see if you can see any physical damage given the metal particles in the oil story you were supplied with.
Really Enjoy Your Videos Guys 👏👍 My Son Wants To Upgrade His 18 Plate S3 To One Of These , But When I Watched Your Two Videos On This 😱😱😱 I'm Definitely Going To Persuade Him Not To ❗ Looking Forward To Next Video 👍
With that much coolant, this fault must have been present for a long time. When you drained the oil it was brown, so guessing there was coolant in there and it’s gone all round the engine. Could the coolant in the oil have caused the bearings to seize? If so, what else has it damaged. Great work btw, you guys make it look easy!
Oil did not mix with coolant , coolant was getting inside combustion chamber and obviously it burn that’s why it was smoking white a bit when we started . Don’t think the engine will have internal damage , oil look sh1t on camera because of my flashlight. Will see in next video what will happen 😋
@@VAGTechnic Appreciate the reply, thank you! You make a valid point. But with this much coolant running into the chambers, some of it would wash down the bores past the piston rings, into the oil. Something happened to those rocker, either oil starvation OR oil contamination. But that’s just a theory from me. In your next video, will you dismantle the charge cooler to see where it’s leaking?
@@jimk7459 not VAG Technic, but I have worked on a fair number of these and let's just say they are not exactly bulletproof. Timing chain needs to be replaced every 65k mls or it could fail, I've seen a couple with damaged pistons (yes that's still a thing) and the wastegate of the turbo wears out really quickly. Coils can go, and if you have a manual 6 speed, those can tear themselfs to shreds too. So plenty of problems but which modern car hasn't these days? Answer: electric Kia's, those seem to be pretty decent ;)
It would be really interesting to see what the differences between the two engines from s5 and rs5 actually are apart from single to dual turbo and water intercooler, there's plenty videos comparing the actual cars but I couldn't find any that just highlight the difference between the engines and pretty sure I can't be the only one that's interested to see if there's any other major differences between those two engines.
Iv had a similar issue on common rail VW Diesel engine. You may find when camshaft removed from carrier there is oil starvation on cam carrier and as it’s line bored may need new ones which is expensive. This usually happens through to much heat!
I own a 2019 rs5 sportback with 25k miles and I now wish I hadn’t seen this video lol. The state of the valves and the fact they cannot be readily cleaned gives me serious cause for pause. Looking forward to the final diagnosis of this engine, but I may be having second thoughts on long term ownership……
I personally don't think I could own a petrol derived Audi. Diesel one's don't seem to appear as frequently on this channel for issues, unlike the petrol variants, and only then it's the Performance ones of the RS type. If you have deep pockets, then I'd have one (RS6) but I don't, so my A7 TDI will do. Good luck with it. Hope it's easy ownership for you.
Am curious about carbon cleaning the valves, is this an engine out job? Was seriously thinking of trading my B8 4.2 for the 2.9 B9 but after watching the video, I have serious reservations.
You have to not only consider that lack of port injections robs you of intake cleaning potential but two more things: "safer" rich mixtures will create more carbon byproducts and high heat and hi power mean looser pistons for more oil blow-by. Its all one big closed system that encounters reinforcing loops!
How the hell can a vehicle manufacturer like Audi be allowed to get away with developing an engine that has so many inherent faults. It’s basically designed to fail
I don't think so. IMHO the main problem is the air intercooler, which is leaky from water side. The coolant is in the engine through piston rings, it's in the oil so lubrication was bad and made these problems with the rock arms and fallen rock arm destroyed camshaft. Why the intercooler is leaky? Because some put there bad tuning box, which overpressured the air intercooler, that's it. I don't thing it's bad engine design, it's bad tuning by bad tuning box. Why ABT tuning has "only" 690N.m and no more, ha ?
@@TheAllEngineering If there is no need to change timing chain during lifetime, so why not? Of course You need to change oil more frequently then Audi said, so no longlife oil change. I have had no problems with timing chain after 170 000 km in S5 4.2FSI when I sold it and after 180 000 km in 3.0TDI, I still have it. Of course You should know that "lifetime" means 150 000km for Audi.
@@sm00077 Poor timing chain life is a common theme in these engines even when following the prescribed maintenance program. The fact that you have to increase the level of maintenance in order to combat a fundamental design floor is not acceptable. The whole short life of the timing chain stems from poor design. Poor combustion leading to contamination of the oil is a contributor to the short life of the timing chain, which comes about because of poor design. The diesel engines do not suffer from this issue so I would not expect you to have issues with your tdi. 150000 km life is a joke.
i hear the rattle type noise kind of sounds like a garden sprinkler during acceleration. I cant reproduce the sound if the car is standing still and just rev it. nor is the sound present while cruising. i just hear it when accelerating and near a wall or parked cars usually make the sound more audible.. what you think would be the problem
I hear many people say German cars are over complicated and Unreliable,while the Over Complitated is true,the unrelaibility is not really true,some engines have their problems but they are all almost trobule free..All I do to my VAG cars is Regular Service with wuality parts..My B8 2.0 TDI 2016 is now on 250.000km(155.000miles) and it has no issues,not a single problem ever...And the same was with my old B7 wich went on to 435.000km (270.000miles)...Even tho they were all Complicated and you could figure out what is what when you removed the engine cover...I like my VAGs,and won't give them up,there is no reason😄
THANK YOU for calling the vehicle's sides by 'driver's side' and 'passenger's side'. Those NEVER change therefore misunderstanding can NOT occur caused by orientation to the vehicle. I just wish EVERYONE would stop being so stubborn and get with the programme.
Problem with that frame of reference is some places have lhd cars! I've had issues with this on my car when looking for a module, due to nearly everyone on the forums being based in North America and having left hand drive vehicles.
I have a 2018 Audi A5 2.0l TFSI (approx 25k miles on the clock). Would I need to look out for the rocker arms, timing chain tensioners and guides failing early too? I only drive 3k miles a year, don't drive it like a sports car etc. The engine is a bit rattly when it starts up from cold, then is quiet once warmed up.
Clever guys no doubt. Engines are just waaay over complicated. Almost every other video it's engine out... won't be buying an Audi anymore lol. Good job there are garages like you that specialise.
so how do you PREVENT this happening? What can you check and watch for? You can't disassemble the engine every service to check the rockers. It seems like the owner was in spec aside from the ECU tune which would have caused more heat & wear?
Really anything with 2.9t or supercharged sucks, even the old 3.0 na engine is garbage. You’re right about the 2.7t in the b5. I currently daily drive a b5 1.8t . Very dependable especially when you can fix your own car.
How many kilometers has the car run and how do the radiator and rocker arms become noticeable? If you noticed a loss of coolant, is it already too late??? In my TPI it says this Audi with BJ. The new thick wheels were installed in 2019, so why the damage? MfG
The 3.0tfsi is better engine? I got b8 s5? Only timing chain and tensioner issues. Mines on 94000 miles engine no sounds cold or warm except for throttle body.
I have a regular A4 B9 with the 2.0L Turbo. Got an ECU tune on it and it's more than quick enough for normal roads. Hopefully my little 4 banger won't have any of these issues! :O
It wouldn’t even be so bad if these engines had astronomical miles but they don’t they are garbage you can tune a mm 7 golf 2.0 to 400bhp with no come back for £500. These things don’t last 30k well done another great video
@@VAGTechnic maybe, but b58 is a very robust engine. Toyota has a whole different QC then the Germans, and the b58 did meet the requirements. This shows that they can create a reliable engine if they want, but still choose not to
Excellent video. The owner should be grateful for what you're doing to vs. replacing the engine. How do you think it happened? Poor maintenance? Using wrong oil? Or, it's an Audi?
Hello WAG Gods, A question for you. I have Audi A6 C6 2009 3.0 TDI 176 KW powerplant. Which maker you prefer to buy: BGA autoparts or Fai autoparts? For whole chain set? FEBI or SWAG dont offer few things like gears for replace old ones.
I bet the coolant in the intake is related to the camshaft issue, especially since all the rocker arms have visible wear. It seems as though water was entering the crankcase, and limiting the lubrication of the cams. After a while, wear would occur until eventually a rocker arm is blown off. It seems far too coincidental that both these things happened at once. And even if it was a fluke problem where a rocker arm spontaneously went bad, that doesn't explain why all the rocker arm bearings were shot.
@@VAGTechnic If the Dealer had of replaced the whole engine (and it came with 2 new turbo's ) it actually wouldn't have been alot more expensive (leaky charge cooler aside) and it would have been good for another 47,000 miles. ;-p
hi, I have problem p0017 on an audi SQ5 with the CWGD 3.0 TFSI engine. Do you think the problem can come from a valve rocker arm like this RS5? Have you had an SQ5 with this fault already? THANKS
They revised the part number twice for the rocker arms: the first (06M109417K) ran to Apr-2017, then the was a second (06M109417L) then finally a third (0P2109417) since Aug-2018. Maybe these were a known weak point and they made them stronger. What part number was on the failed ones? Edit: look up EA839 rocker arm failures, seems to be a thing - discussed in forums
Yes , the first two part number are actually the same rocker arms, but the 0P are the ones intalled after July 2019 . I rang TPS with most of the cars for sale till 2019 and all of them have the 06M ones from factory, RS4/RS5, S4/S5 B9 ...
The 3.0l as fitted to the S4/S5 also had similar revisions with the first (06M109417H) until sep-17 then a second (06M109417L) and again a last at Aug-18 (0P2109417) makes me nervous owning a may 18 S4 hopefully these failures are only the affecting the first revisions but as there was another in Aug-18 I’m not so sure

Firstly, top video, excellent diagnosis I’d definitely come to you guys in a heartbeat with my car! Secondly, I was in the process of buying one of these but paused due to several factors. That pause allowed my wife some time and as a result we bought a new horsebox, seriously expensive thing with very costly maintenance I constantly complain about! That said, it’s now looking cheap compared to running and maintaining one of these! Feel like I’ve dodged a bullet, won’t now be getting a B9 S4, certainly not one with any sort of mileage on!
Ouch. I’m definitely sticking with my classic AAN.
Very Good Video! Always love to watch :) In my Shop we also had a Rs5 with less Milage and we had the exact same issue, but due the car was new back then and it was still in warrenty we were looking way longer then you Guys did! Well done
Thanks , we actually spent two days making it run , than once the engine is out it was matter of time to find it 😄 it is sad what happened, I thought when I saw the 2.9 first I was like woooow , good platform , few years later I come to decision I have to put my B5 S4 back on the road , no chance I’m getting 50k car and facing these issues
@@VAGTechnic isnt this issue fixed? What about the platform don’t you like?
It was looking promising at the start of the first video ,,, but its gone downhill somewhat since then. But well done , just one of those things I guess , my old 2.5 diesel allroad did something similar when the cam lobes wore , the followers just fell off a few valves and into the head luckily a set of cams and followers sorted it out.
Really interesting to watch. My B9 S5 currently has its engine out at a local garage as there isn’t any compression in one cylinder. Garage suspect its due to rocker arm issues 🤦🏻♂️ Audi main dealer say they do not seen regular issues on these engines!! Really keen to see how this all ends up as you are further ahead on this car than they are on mine - hopefully I won’t have the other issues that plague the 2.9 though???
If you have no compression that’s bad …
@@VAGTechnic oh god please don’t say that! Any idea what might be causing that then?
same problem here s5 b9 100.000 km same story
@@privatprivat5431 did you fix and keep the car or sell on in fear it would happen again? Found out now mine has damaged the crankshaft and cylinder head!!
@@Ben-hk9hc No, it is in the workshop at the moment and the engine has yet to be removed. I had shavings in the oil, which would mean my entire engine was gone. Was your car stock? What are you doing now?
After watching this, I'm very glad to have the supercharged 3.0 CREC. Engine out for carbon cleaning? No thanks. Great channel - subscribed!
You guys should be proud of yourselves, you both are top Motor Engineers and Looks like you run a Good Business. Keep it up
Keep up with the good work buddy, I can tell you as an Audi technician that all the new models are plagued with problems 😂. Byw stay away from the Q8. . In my personal opinion ppl just pay high prices for a product that is not worth the money.
Rs3 ftw… Strong motors, make good power , reliable, and in terms of vag they’re not the worst thing to work on.. I think the driveshaft being frail af is stupid but aside from that not too bad… I was jdm back in the day, but the interiors just aren’t up to snuff I guess you’d say. It like you want to have a nicely modified fast car but need a nice interior for the adult side ..lol🤣🤣 basically need to make enough money to not care about cost or make some sacrifices when choosing a vehicle you intend to modify🤷🏼♂️. Great channel, great info 🤜🏻🤛🏻
I have a 2010 A5 ..apr_stage2 , and good bit of other mods.. and a 2014 Q7 prestige also modified. ( but not many tuning options in the 4L ) so just racechip tuning box and throttle controller along with other mods. Luckily no issues with either but want to upgrade mine and only real option is the rs3 basically too scared to get anything s5 and up . 1 can’t afford it brand new so it’d be used and 2nd it won’t be staying stock. 🤷🏼♂️
Thank you for your vlogs! The vlogs are very nice to watch and nice editing skills. You guys have an very sweet workshop and very nice cars.
Keep up the good work and looking forward to your news vlogs.

@@VAGTechnic Yes, that would be nice! I guess I will loose you guys at the red light district?😉😉🤣🤣
The cleaning of the inlet valves is a manual thing, since no fuel will flow over the valves, no fuel additive will work.
Does it mean that the Porsches with the same 2.9 can suffer from the same problem too?
I thought my BMW M62tu V8 was complicated. This Audi V6 makes that motor look like a lawn mower engine. That said I'm glad technicians like this exist.
I would not in a million years buy a car with this engine.
Or any brand new car. It's not only the complexity and unnecessary over engineering that appals me. It's the insane amount of work you have to do to maintain or repair these.You can't reach anything without removing the engine.
The keeping cost is insane I think 😂
I completely agree with what he said in the video, 2.7TT is an amazing engine. Simple yet powerful. Also the 1.8T is still a phenomenal engine.
Yeah absolutely all car companies should be made to produce an engine and transmission that will last at least 500,000km with nothing more than simple servicing and if not they should be made to fix at they’re own cost.
As a mechanic I’ve never thought Audi as a well thought out engine designer as in this case !
i rather have any JDM sport car than any VWAG or european , thank you for sharing the awesome video VAG Tec !
Coming from an LS guy with notorious rocker arm needle bearing failure, hopefully you find all the needles before reassembly. In the American Engineered(haha) LS those needles work their way down to the oil pan, eventually getting sucked into the oil pump and wreak even more havoc than the part actually failing.
Congrats, very good content an actual mechanic in youtube!!!!
What an absolute nightmare. So complicated, I’d be shitting myself every time I’d drive an Audi v6s or v8🤯. Maintenance must be more expensive than maintaining the wife and kids🤪
Actually on older models its not even bad and the drivetrains are pretty strong and reliable
Bro it’s total shit
That's why I stopped at 2016/2017 models...too much complexity unless you have deep pockets. Just sold a 2007 S4 because it just became a handful.
rich mans toy. soon as the warranty is up u get shot of it.
i wouldn't own an audi for free. over complicated shite.
@@thebrownthomascrown917 did the engine survive tho?
Is there a video on how to set the timing on the heads? Like if cam needs replacement . Can’t find info on cam position of the 2.9 2018
Great service! Great evidence of technical knowledge! I'm surprised Audi doesn't pay UA-cam to censor your channel, because for a car of this age and mileage to have such a catastrophic failure screams protentional buyers to runaway from this brand! I never seen so many timing issues documented on one brand regardless of the engine. Awful!
we have to thank freedom of speech for that!
And on top of that they put the timing chains at the rear of the engine so they cannot be easily accessed. They went out of their way to engineer it poorly !!!
Going to stick with my little Peugeot. Thanks for putting me off this nightmare 🙂👍
I wish more people could see your content and learn to stay away from these cars and avoid financial ruin.

Great work gents. Fix her up and bang it back together and you just saved the owner 10,000 pounds. Nice one
OH BOY OH BOY OH BOY...... sorry to see what you have found, but thank you for sharing.
Wrong oil caused rockers to seize? Coolant contaminated oil? In any event, whoever was servicing this vehicle didn't check for known issues like the intercooler failing, leading to the failure of the rockers. Not sure if it was a contributory factor, but the hot V turbo location does generate a lot of heat where nobody wants it.
With all the sensors on that motor seems like a code would be thrown if it had that much water going through it and if not, they got a sensor for everything else but you got coolant going through the intercooler and no way to tell it's gone bad?
If a recall correctly from the earlier video you were getting timing error messages, I,guess that’s not so surprising now. If it had been me I would have wanted to take these heads of first and put a scope down to look around and see if you can see any physical damage given the metal particles in the oil story you were supplied with.
Really Enjoy Your Videos Guys 👏👍
My Son Wants To Upgrade His 18 Plate S3 To One Of These , But When I Watched Your Two Videos On This 😱😱😱 I'm Definitely Going To Persuade Him Not To ❗
Looking Forward To Next Video 👍
With that much coolant, this fault must have been present for a long time. When you drained the oil it was brown, so guessing there was coolant in there and it’s gone all round the engine. Could the coolant in the oil have caused the bearings to seize? If so, what else has it damaged. Great work btw, you guys make it look easy!
Oil did not mix with coolant , coolant was getting inside combustion chamber and obviously it burn that’s why it was smoking white a bit when we started . Don’t think the engine will have internal damage , oil look sh1t on camera because of my flashlight. Will see in next video what will happen 😋
@@VAGTechnic Appreciate the reply, thank you! You make a valid point. But with this much coolant running into the chambers, some of it would wash down the bores past the piston rings, into the oil. Something happened to those rocker, either oil starvation OR oil contamination. But that’s just a theory from me. In your next video, will you dismantle the charge cooler to see where it’s leaking?
@@SaqibKhaliq you will get answer in the next video again
@@VAGTechnic what's your opinion about 1.4 tsi 122 engine? (golf 6)
@@jimk7459 not VAG Technic, but I have worked on a fair number of these and let's just say they are not exactly bulletproof. Timing chain needs to be replaced every 65k mls or it could fail, I've seen a couple with damaged pistons (yes that's still a thing) and the wastegate of the turbo wears out really quickly. Coils can go, and if you have a manual 6 speed, those can tear themselfs to shreds too. So plenty of problems but which modern car hasn't these days?
Answer: electric Kia's, those seem to be pretty decent ;)
Excellent video. Would have nightmares putting that lot back together
wow. I thought the 2.0 EA888 was bad........ this is on another level
What have you heard abt the ea888s? I have a new S3 🥺
It would be really interesting to see what the differences between the two engines from s5 and rs5 actually are apart from single to dual turbo and water intercooler, there's plenty videos comparing the actual cars but I couldn't find any that just highlight the difference between the engines and pretty sure I can't be the only one that's interested to see if there's any other major differences between those two engines.
Two completely different engines lol
@@Rising666 they are not that different you'd be surprised
Iv had a similar issue on common rail VW Diesel engine. You may find when camshaft removed from carrier there is oil starvation on cam carrier and as it’s line bored may need new ones which is expensive. This usually happens through to much heat!
Was going to buy a 2018 B9 S5 SB but I changed my mind after this video. Any recommendations for a fun, luxury, and reliable daily?
hi good day sir vag. do you have idea about torque of main bearing cup connecting rod cylinder head bolt for RS5 audi 2018 v6 tnx...
Super video a obsah celkovo, len tak ďalej hoši 🙂
I own a 2019 rs5 sportback with 25k miles and I now wish I hadn’t seen this video lol. The state of the valves and the fact they cannot be readily cleaned gives me serious cause for pause. Looking forward to the final diagnosis of this engine, but I may be having second thoughts on long term ownership……
Sell it asap
It's a known issue. It was fixed by Audi on models from 06/2018.
Diesel for the win 😅 Diesel valves coke up like this but it has far less of an effect on performance for some reason.
Dump before it makes you walk home one day.
I personally don't think I could own a petrol derived Audi. Diesel one's don't seem to appear as frequently on this channel for issues, unlike the petrol variants, and only then it's the Performance ones of the RS type. If you have deep pockets, then I'd have one (RS6) but I don't, so my A7 TDI will do. Good luck with it. Hope it's easy ownership for you.
Am curious about carbon cleaning the valves, is this an engine out job? Was seriously thinking of trading my B8 4.2 for the 2.9 B9 but after watching the video, I have serious reservations.
You have to not only consider that lack of port injections robs you of intake cleaning potential but two more things: "safer" rich mixtures will create more carbon byproducts and high heat and hi power mean looser pistons for more oil blow-by. Its all one big closed system that encounters reinforcing loops!
How the hell can a vehicle manufacturer like Audi be allowed to get away with developing an engine that has so many inherent faults. It’s basically designed to fail
I don't think so. IMHO the main problem is the air intercooler, which is leaky from water side. The coolant is in the engine through piston rings, it's in the oil so lubrication was bad and made these problems with the rock arms and fallen rock arm destroyed camshaft. Why the intercooler is leaky? Because some put there bad tuning box, which overpressured the air intercooler, that's it. I don't thing it's bad engine design, it's bad tuning by bad tuning box. Why ABT tuning has "only" 690N.m and no more, ha ?
@@sm00077 So putting the timing chain at the rear of the engine is a good design then ??
@@TheAllEngineering If there is no need to change timing chain during lifetime, so why not? Of course You need to change oil more frequently then Audi said, so no longlife oil change. I have had no problems with timing chain after 170 000 km in S5 4.2FSI when I sold it and after 180 000 km in 3.0TDI, I still have it. Of course You should know that "lifetime" means 150 000km for Audi.
@@sm00077 Poor timing chain life is a common theme in these engines even when following the prescribed maintenance program. The fact that you have to increase the level of maintenance in order to combat a fundamental design floor is not acceptable. The whole short life of the timing chain stems from poor design. Poor combustion leading to contamination of the oil is a contributor to the short life of the timing chain, which comes about because of poor design. The diesel engines do not suffer from this issue so I would not expect you to have issues with your tdi. 150000 km life is a joke.
Looking forward to the update video any idea when this will be uploaded?
i hear the rattle type noise kind of sounds like a garden sprinkler during acceleration. I cant reproduce the sound if the car is standing still and just rev it. nor is the sound present while cruising. i just hear it when accelerating and near a wall or parked cars usually make the sound more audible.. what you think would be the problem
Lovin' the GTA theme music dude, takes me back!
Anticipation has never been so high 😭😭😭
Great video! I’m guessing this was an early b9. Manufacture date before 6/19. Audi identified this issue and updated the rocker arms.
i love your vids!! soundtracks are wicked!!!, presentation!! is wicked!!
I hear many people say German cars are over complicated and Unreliable,while the Over Complitated is true,the unrelaibility is not really true,some engines have their problems but they are all almost trobule free..All I do to my VAG cars is Regular Service with wuality parts..My B8 2.0 TDI 2016 is now on 250.000km(155.000miles) and it has no issues,not a single problem ever...And the same was with my old B7 wich went on to 435.000km (270.000miles)...Even tho they were all Complicated and you could figure out what is what when you removed the engine cover...I like my VAGs,and won't give them up,there is no reason😄
THANK YOU for calling the vehicle's sides by 'driver's side' and 'passenger's side'. Those NEVER change therefore misunderstanding can NOT occur caused by orientation to the vehicle. I just wish EVERYONE would stop being so stubborn and get with the programme.
Problem with that frame of reference is some places have lhd cars! I've had issues with this on my car when looking for a module, due to nearly everyone on the forums being based in North America and having left hand drive vehicles.
I have a 2018 Audi A5 2.0l TFSI (approx 25k miles on the clock). Would I need to look out for the rocker arms, timing chain tensioners and guides failing early too?
I only drive 3k miles a year, don't drive it like a sports car etc. The engine is a bit rattly when it starts up from cold, then is quiet once warmed up.
Clever guys no doubt. Engines are just waaay over complicated. Almost every other video it's engine out... won't be buying an Audi anymore lol.
Good job there are garages like you that specialise.
We can start filming oil changes and pads replacement if that helps 😅
@@VAGTechnic 🤣🤣
so how do you PREVENT this happening? What can you check and watch for? You can't disassemble the engine every service to check the rockers. It seems like the owner was in spec aside from the ECU tune which would have caused more heat & wear?
Please, I'm in Brazil with an Audi Q7, V6 3.0 2021 EA 839 engine. I need to buy this axle braking tool, could you provide the correct model?
Any updates coming soon?
Wasnt rocker arm upgraded on 19 onwards?
Really anything with 2.9t or supercharged sucks, even the old 3.0 na engine is garbage. You’re right about the 2.7t in the b5. I currently daily drive a b5 1.8t . Very dependable especially when you can fix your own car.
How many kilometers has the car run and how do the radiator and rocker arms become noticeable?
If you noticed a loss of coolant, is it already too late??? In my TPI it says this Audi with BJ. The new thick wheels were installed in 2019, so why the damage?
MfG
Great channel guys. Keep up the good work.
Did they ever add port injection to this engine in later model years? Or in the 3.0 V6 in the S5?
The 3.0tfsi is better engine? I got b8 s5? Only timing chain and tensioner issues. Mines on 94000 miles engine no sounds cold or warm except for throttle body.
they are good these are good as well but again Audi messed up
@@VAGTechnic thank you for reply your one genuine guy. Any work it's to you!
Looks like a nightmare to work on. Great insight tho 👍
I have a regular A4 B9 with the 2.0L Turbo. Got an ECU tune on it and it's more than quick enough for normal roads. Hopefully my little 4 banger won't have any of these issues! :O
This oversized rocker arm bearing issue is fixed now by Audi I understand , is that correct after 2019 they altered the structure of the bearings ?
Yes
It wouldn’t even be so bad if these engines had astronomical miles but they don’t they are garbage you can tune a mm 7 golf 2.0 to 400bhp with no come back for £500. These things don’t last 30k well done another great video
Disappointed is the biggest understatement ever, I would be gutted.
Hi mate is there a special tool for timing to take head off s5 b9 thanks
Weren't the rocker issues limited to any unit manufactured prior to 6/19?
Anymore updates?
Yes
Good job guys. BR from Poland ;-)
Now a 340/440/m2 non comp seems like a good option. These engines are really reliable, even Toyota use it in their Supra
They had no choice 😅
@@VAGTechnic maybe, but b58 is a very robust engine. Toyota has a whole different QC then the Germans, and the b58 did meet the requirements. This shows that they can create a reliable engine if they want, but still choose not to
BMW's enigine reliable? 😂 Good joke.
Excellent video. The owner should be grateful for what you're doing to vs. replacing the engine. How do you think it happened? Poor maintenance? Using wrong oil? Or, it's an Audi?
My tip is wrong oil, poor service shop not checking for known issues like intercooler failure.
Its an Audi, car is a total POS, ever engineered, under tested, unreliable, junk
Hello WAG Gods, A question for you. I have Audi A6 C6 2009 3.0 TDI 176 KW powerplant. Which maker you prefer to buy: BGA autoparts or Fai autoparts? For whole chain set? FEBI or SWAG dont offer few things like gears for replace old ones.
I bet the coolant in the intake is related to the camshaft issue, especially since all the rocker arms have visible wear. It seems as though water was entering the crankcase, and limiting the lubrication of the cams. After a while, wear would occur until eventually a rocker arm is blown off.
It seems far too coincidental that both these things happened at once. And even if it was a fluke problem where a rocker arm spontaneously went bad, that doesn't explain why all the rocker arm bearings were shot.
Coolant never get mixed with oil
Great work gents, the cost will be over the roof 😢
Our bill is probably over the roof but the one from dealers was around the moon twice 😂
@@VAGTechnic If the Dealer had of replaced the whole engine (and it came with 2 new turbo's ) it actually wouldn't have been alot more expensive (leaky charge cooler aside) and it would have been good for another 47,000 miles. ;-p

Yes Month ago
@@VAGTechnic What did you do for the repair? thanks
They revised the part number twice for the rocker arms: the first (06M109417K) ran to Apr-2017, then the was a second (06M109417L) then finally a third (0P2109417) since Aug-2018. Maybe these were a known weak point and they made them stronger. What part number was on the failed ones?
Edit: look up EA839 rocker arm failures, seems to be a thing - discussed in forums
Yes , the first two part number are actually the same rocker arms, but the 0P are the ones intalled after July 2019 . I rang TPS with most of the cars for sale till 2019 and all of them have the 06M ones from factory, RS4/RS5, S4/S5 B9 ...
The 3.0l as fitted to the S4/S5 also had similar revisions with the first (06M109417H) until sep-17 then a second (06M109417L) and again a last at Aug-18 (0P2109417) makes me nervous owning a may 18 S4 hopefully these failures are only the affecting the first revisions but as there was another in Aug-18 I’m not so sure
