I've removed the plastic under pan cover on my V10 TDI. This help with the Cali heat alot. My heaviest towing was a mini CAT. Excavator with 2 additional buckets. No sweat. I will not disclose the weight. LOL
Tim Leng haha nice man. Must have been right at the weight limit. Lol
@@spottedeuros1529 He did 9500+ lb
I would not call that overheating to be honest, more like an honest gauge. Looks like around 238F which is warm, but not overheating. Most cars don't activate cooling fans until 225 ( at least the high speed fan). Get yourself a scan gauge to monitor what the computer sees. Most auto parts store have them, plus into the OBD2 port. Thanks for the video! I am looking to purchase a 2010 TDI and its nice to see how they pull.... MUCH less drama and fuss than my Tundra for sure.
Yea, I would agree. I have defiantly been surprised by how well it tows. Especially at max towing capacity. What year is your Tundra?
@@spottedeuros1529 It is a 2014. They tow well, but the transmission is always hunting around all over the place, drives me crazy, and peak torque is at 3600RPM. Add some altitude and it can be weazing over a mountain pass. I am wondering if your TDI needs a thermostat? Hard to say....Could just be the nature of the beast. I will say that nothing beats a v-8 for day to day without the complexities of turbos and exotic fuel systems like the TDI.
Luke Davis Your tundra sounds like the Touareg V8 I have. This Tdi Touareg is surprising better at maintaining speed. Doesn’t seem to matter how fast I’m going. Rarely downshifts to 5th unless it’s a big hill. On the other hand my V8 wants to constantly downshift.
Must be the torque that makes the difference.
238 isn't overheating 245-250 is.
Most of these newer diesels run close to 220 in normal driving because of the stupid emissions crap on them.
Most of the times when a diesel engine overheats like that, under heavy load, is because of restricted exhaust system, maybe clogged cats. It needs to let the heat go and if its restricted it will keep a high pressure and high heat on the exhaust manifild/turbos/cats. Get some high flow cats or clean yours. Thats why it jumped when you pushed it and kind of lowered a little when you let off to 55
Really good info. Thanks! I've always wanted to delete the emissions system and free up some of the air flow on one of these. I'm sure you could get a big improvement.
@@spottedeuros1529 d3l3te that thing and it will be an entirely new vehicle. Way more power, better fuel economy and the engine will last much longer! Did my titan xd with the Cummins 5.0 and made a huge difference in throttle response amd performance, even in the 0hp setting.
@@Jackmerius_Tacktheretrix yup
@@spottedeuros1529 it definitely overheated because it has Dpf and Egr
Golden. This comment helped me narrow down an overheating case on my Treg. All fixed now by cleaning the clogged cat
U have crazy good content for people who are interested in towing especialy with the tdi. If u plan to change the oil and flush the radiator(coolant). It would be rly interesting to see how it would perform after those changes. On that same hill with the same load. Keep it up dude. Greetings from europe, i plan to buy a touareg v6 tdi and tow with it, love your videos!!
Lowkey Thanks for the support! Great idea. I might just do that.
Overall a Thumbs Up! But man, you cannot do this with any other 6 cylinder SUV crossover,not even close. Good commentary, subscribed.
Exactly the video I was looking for! I'll be using a TDI Touareg as my daily driver as well as my tow vehicle for my old Nissan for track days. The Nissan only weighs about 2800 lbs so I think it'll be just fine. A coolant flush, some Rotella T6 5w40, and split the trans cooling into it's own cooler instead of having it cycle through the coolant radiator and I think you'll see a drastic drop in temps.
A Touareg could handle that just fine. Could even be just a Gas V8 too.
I have wondered about setting up a tans cooler. It doesn't has one stock.
@@spottedeuros1529 I could be wrong, but I believe the trans cooler is incorporated into the radiator so radiator does double duty for coolant as well as trans fluid. When you separate the cooling loops, you improve the cooling efficiency of both systems.
Aaron S You are right. The coolant and trans temperature are always the exact same.
@@sullygtx9350 I have wondered about how installing a separate trans cooler in front of the radiator affects the engine's cooling. On one hand you somewhat separate the heat and stop directly dumping all the transmission's heat directly into the coolant, but on the other hand, the trans cooler somewhat blocks and preheats the airflow to the radiator and condenser. Obviously the ideal solution would be to put the cooler somewhere other than in front of the condenser, but this generally isn't practical because that's usually the only place with good enough airflow. Or better yet, get a manual so you don't have to worry about any of that :)
And yet, it did NOT "Overheat". False advertising. And it got better fuel economy than my Landcruiser 100 series pulling NOTHING. Remarkable.
As others have stated, No cruise control, use gears instead of brakes, hopefully with trailer electric brakes and trailer modulator, and then use heater if wanting to accelerate with OVER MAX load from bottom of a BIG hill/mountain. Still it did FANTASTIC. Did NOT overheat. With everything against it and done wrong.
With my Touareg 2 v8 4.2 FSI (completely different and more powerful engine from the old 4.2) I towed 8000 pounds dual axle cargo trailer from California to Texas. There were several hills like this and I was driving 70-80 everywhere - no overheating at all.
The only overheat I saw in my Touareg was on Pikes Peak - no towing just 4 people and full of stuff. And it was drive-train overheat.
240'F =115'C - really hot coolant - you should check a level or make heater inside in full hi temp
Apparently it is normal... My V6 tdi Amarok does the same. As soon as the oil temperature rises above 120c the coolant temperature goes up. In the owner manual it also says it is fine. I once had a faulty temperature sensor on my v6 tdi Touareg so the car though it was overheating. First the ac shutdown, then alarms (one in the dash and another one somewhere in the rear of the car) and flashing lights and limp mode. If it overheats you'll know.
I wish we had the Amarok here. Good looking truck. Interesting to hear that all Tdis seem to run this hot when pushed.
That was an interesting experiment Josh. Thanks for showing and your good commentary. I’ve just got myself an R50 and moving to that from a 2014 TDiV6 Touareg which tows my 3000kg caravan admirably. Most driving I do is flat terrain so no real challenges. Keen to see how the V10 deals with it. Good stuff listening to your clips.
I still get surprised by how well the Tdi tows. I use to tow with a V8 touareg and I was constantly having to watch my rpms and shift manually according to the terrain. I leave the Tdi is Drive and let it do it's thing. Hardly every shifts into 5th gear.
Okay, video ended before the car overheated. Maybe I don't have the full video available, but in everything I saw the temperature remained well below the red zone in which it starts to get risky. If you tow a lot in this, user 10w-40 or 15w-50
Your video started at the chain up area at the bottom of Parley's. The elevation there is roughly 4600 feet (the Salt Lake airport is 4200 feet). The top of the summit is called Parley's Summit and has an elevation of 7,000 feet and back down on the Park City side to about 6,400 feet. So the climb in the video was about 2,400 feet.
The EGR coolers on the 3.0TDI’s is the main downfall of these. Under higher loads, the EGR cooler dumps super hot coolant into the cooling loop and the system isn’t able to cope causing the temps to go up. My 2014 does the same in similar circumstances.
I will be buying a friends 15 Touareg TDI next year and will be towing my camper trailer and UTV/trailer. Certainly won't be that heavy so it's nice to know I'll be well within the zone. I agree.. Oil change often to Amsoil and a coolant flush are in order on a used vehicle. Looking forward to more TDI Touareg videos.
dddire straits Awesome! I’d love to get a newer generation Touareg. These Touareg Tdis tow so well. Thanks for the support.
@@spottedeuros1529 You're welcome my friend. Yes, it's a pretty sweet tow rig. Great fuel economy. This one is a garage queen, with only 45k KM's on the clock and dealer maintained. I've used it to tow my camper a few times already as I'm between tow vehicles. 70mph up hills all day long and no over heating issues at all. But my trailer fully loaded is well under 5k lbs.
You are off on the math, 2500 lbs trailer + 6,000 lbs. V8 Treg = 8,500 lbs. (800+ lbs. OVER MAX limit) and then UPHILL on a warm day?
The real video starts just around 5:00.
really did a number on the oil. If I did that hill every day in a commute I would change it every 2500 miles lol
Defiantly putting the Touareg to the test.
You need a V10 for a comparison.
When was the coolant last changed? I would personally change the Easter coolant after 100k
Thanks for the videos. Did this have the tow pick age with extra trans cooler?
I know I have the factory hitch but I don't have a trans cooler.
You should have blasted the hot air..temp would have gone down
cooksey187 didn’t think of that at the time.
@@spottedeuros1529 Shouldn't be driving this then.
Curious if you had oem tow module...it changes alot of thr engine cooling parameters. If you just put an after market harness on you won't have that.
OEM hitch. I had to add the connected but the wiring was there. No trans cooler.
I guarantee its because of the emissions crap, and these vehicles don't have the huge heavy duty radiators that diesel pickups have.
Gotta downshift going downhill my man. Let the driveline help the brakes.
omnipresent video the transmission in these Touareg are not its strong point. I’m always hesitant to use it when going down hill. Maybe I shouldn’t worry but I rather wear through the brakes and not the transmission.
@@spottedeuros1529 There isn't really a reason to worry about engine braking on the way down as long as you aren't exceeding redline, there is much more stress on the engine and transmission while climbing than travelling downhill. The brakes aren't designed to be used constantly when descending and can easily overheat and fade, or at the very least wear out more than necessary.
Was thinking about getting a truck gmc 2500 to tow other vehicles or trucks.
But I think I'm going to go with a v8 touraeg, I live in Florida so I'm sure it won't have any problem towing anything.
I had a V8 Touareg. Loved it. I have a few videos on it.
Bat Man get a chevy HD gas if you don’t tow heavy
Have you tested the V8 Touareg on the same hill pulling the TDI? I'd like to see if the V8 would have the same heating issues. I love the Touareg TDI BTW, my dream vehicle.
I have done a video with the V8 going up this same hill. It was just towing a MK4 GTI though. Here is the link:
ua-cam.com/video/SDZgoXmMviE/v-deo.html
@@spottedeuros1529 Thank for the new link, I just watched it and I'm glad to see the V8 did well, BUT your load is not the same, there's something like 2500 lbs difference between the MK4 GTI and the Touareg TDI (comparison of apples to oranges), not really the same. Still, pretty informative, thank you.
Hello what about a bit oldee ones like the 2011-2014 ? I am thinking of towing a travel trailer with it , my problem is my trailer is a bit longer. Roughly 27'. And 5200 lbs. I'm worried this is too much for the midsized suv
If it’s a TDI it’ll probably do it pretty effortlessly. Gas V6 might have a hard time.
8000 pounds is over towing rating. FYI 😊
dont have opportunity but wish to try something like that with my V6 , maybe can do it even 70mph with very high rpm in 3rd or 4th gear . who knows HP VS TORQUE :)
The first Touareg I had was a gas V6. I towed with it a couple times. Lacks power when without towing. It would be interesting to see a direct comparison though.
Not good, this thing could easily fail under that kind of load. According to the car it was only 75 out and the coolant was running as high as 240, which is the highest I would ever want to see. It was climbing quickly before you backed off too. Add another 30 degrees to that for a 100+ degree day (or more if someone was pushing it harder) and the coolant would be up to 270+ degrees and boiling over and you would be stranded and likely have serious engine damage if you didn't stop quickly. As other have said, shutting off the AC and turning the heat on goes a long way towards keeping the engine cool, but this should not be necessary on any correctly designed vehicle presuming it is in decent condition and operating within its limits.
Plenty of power but it started to get hot. I’m thinking about doing this again. See if taking it slower at the start will make a difference.
@@spottedeuros1529 That would be a good test. Also, make sure there is no leaves or other debris blocking airflow through the radiator, that will make it run hot too. I have seen vehicles where the front of the condenser looks pretty clean but there is a lot of crap between the condenser and the radiator blocking airflow. If a lot of fins on the condenser or radiator are bent over that can block airflow and make it run hot too. An exhaust restriction such as a plugged cat or DPF will trap a lot of heat in the engine. This vehicle has an oil cooler that is cooled by the engine's coolant, so if the cooling system isn't working well and the coolant gets hot the oil cooler won't be able to effectively cool the oil.
I have 2013 Touareg TDI with the CNRB engine where they updated the EGR cooler, cooling system, and oil systems. Sadly it suffers from the same problem as yours when towing 8000lbs at high elevation (6000ft+). I thinking it has to do with the EGR dumping a lot more of exhaust gasses into the intake at high elevation to keep the "polar bear protection system" found in the exhaust from clogging up, which makes the intake temp way too high and starts bringing EGTs to metal melting temps. I live in Northern California, and can't really emissions delete my Touareg so I'm stuck just slowing down and taking it easy up the grades at high elevations.
It would be great to see what difference deleting the emissions would have on towing at high elevation. (besides having more power!!!)
Max Hauser great info man. I would like to do some deletes on one of these to see some of the differences.
I don't think the egr would be working under load. The intake would be under high boost pressure, you would be better off removing the cats
@@farnzy2011 An EGR works overtime when it has a load on it as well as the EGR cooler. that's why it's there to recirculate the soot made from a diesel under heavy load. next Gen commercial cummins motors are getting rid of them because they are antiqued carry-over bandaid from Gas cars in the 70s. BTW Modern after-treatment systems flow as well as a straight pipe with stock tuning. VW/Audi is the king of high-performance diesels, won't imagine them putting a restrictive cat on a diesel.
I think you have an issue somewhere. I tow a Takeuchi 3 ton mini digger daily with my v10 over some of the steepest hills in Ireland and the oil and coolant temps barely move. Although mine is 2004 so pre DPF.
isyours a 3.0 or 2.5 diesel i was going to buy a 2.5
Not sure. Some other people have commented about the same kind of temps when they are towing similar loads.
paddy k 5.0 V10 Diesel
Get a V10 TDI for that kind of pulling!
That would be awesome!
If you have a certain power output, you can pull so much______whats the big deal???
V6 diesel or v10?
How much mpg when towing on regular roads
It's not overheating, just the way it is. Maybe a coolant change would help, but I doubt it. I have a 2013 Touareg TDI, tow a toy hauler at 5600 pounds, full summer heat (92°F around here) and even up steep grades the coolant temp never goes above 220°F, and drops right back to 210°F when back on the flat.
Yea, I’m not sure when the coolant was changed last so it’s probably good to change that. The V8 Touareg that’s on the trailer seems to stay cooler but it also doesn’t have a turbo putting out heat.
@@spottedeuros1529 A diesel doesn't really care about heat soak. They run great when hot. No such thing as pre-detonation like a gasoline engine. Make sure to use synthetic oils. Almost 95K miles on my TDI, and still runs great.Synthetic oil changes at 10K. Just did the transmission FLUSH 12 liters old fluid OUT and new fluid in using the Transmission cooler lines. Old fluid looked fine, just slightly dark but still strawberry color. Don't trust in the instrument cluster temp gauge for accuracy, use a scan tool like an OBD2 reader and a phone app or VCDS to get an accurate reading on temps.
This is the same temp. range as my V10 TDI.
7700 lbs ?, Thought this was the same as the Audi Q7, which I thought was a max of 6600 lbs ?
The Touareg is more than the Q7. I believe the Q7s of this same year only have a towing capacity of 5,500.
Imagine doing that with land rover tdv6 ........
What is make and model of your trailer? I need something similar for mt treg. . Cheers.
It's a home built trailer. The story I got when I bought it from someone else was that it was built by a guy who made trailers. Super strong and overbuilt in a lot of ways. Only real issue is that it's pretty heavy.
@@spottedeuros1529 Thx. The tilt decks I'm finding in 16 and 18' don't tilt the whole deck width, so Treg wont fit on them.
Hard to see but looks like exhaust tips are black which shows you have a failed DPF. I've seen touaregs pull over their weight limit without a hiccup up steep inclines. This vehicle needs maintenance.
No black smoke. Pushing the Touareg to the limit in the hot summer. I will say I could have driven better but it's hard doing it all at once.
Did you check fluids before you started?
Always.
👍👍👍
What brand is ur hitch
OEM
Very nice video!
Seems Touareg its not that powerfull climbing!
Maybe the 3.0 V6 tdi its better for the job!
I usually tow a forklift in my trailer, making a set of 5.500kg.
On a Nissan Cabstar 2017 150hp I cruise at 95km/h, but good hills speed goes down to 80km/h.
I was expecting lot better in this Touareg!
Any way this is a very good knowledge Video!
It is the 3.0 tdi diesel
Which TDi v6 or v10
Colin Kensley V6. I’ve always wanted a V10.
@@spottedeuros1529 I would love to see a comparison video of a v10 doing the towing....I'm surprised that the v6 overheated I tow my boat up a long hill with mine no problems
Colin Kensley Yea me too.
We are going to flush out the fluids and see if it makes a difference. We got this car at auction so service is unknown.
Was running a gross weight of about 8800lb with my v10, got hot but must have been high EGT finished the VNT off and put me in limp mode before overheat :-(
This is ultimate stupid test...
Why is ur face so big?
WHYYYYYYY????????
