Yes I was hesitant to remove the cooler but only did it for reliability sake. I wanted it out because I heard some owners had issues with them internally cracking and leaking coolant that would get sucked into the engine, and destroying the engine. This seems to be isolated to the earlier 3.0L TDI’s, but I didn’t want to chance it. My warmup times are not really affected in frigid weather. It’s heat retention that’s an ‘issue’. It will drop coolant temp very fast under low load or idling. City driving in -20 or colder, and you’ll never see 70 degrees Celsius coolant temp. With the aux heater, it makes no difference to me. It kicks off after 70 degrees, and kicks on below that. I’m surprised that the Q7 doesn’t have it. You may want to double check that, because I was always under the impression they had it like the touareg(and I believe, the cayenne). If in fact you don’t have it, and you’re not having any problems, I’d leave the cooler in. You will have a similar-to-stock warmup experience. The EGR cooler is always open for exhaust gas to enter it, so the coolant that goes inside is always heated by exhaust gas. So it will warmup quicker than mine does for sure. So if I were you, leave it in. You shouldn’t notice much of a warmup difference. Keep in mind as well, being deleted, these engines use very little fuel idling or at low speed when deleted and tuned. When idling on a stock 3.0L, you should notice around 0.9-1.1l/hour consumption. Deleted, mine uses 0.6l/hour. So that’s even LESS heat being generated.

So you kept the EGR cooler on your deletes? This is kind of along the way I was thinking, as my Q7 runs super cold in the cold winter months, even in factory form with all emissions working properly still. Do you mind sharing the exact set up you used for your deletes?

They do run cold in the winter for sure. I did DPF EGR and add blue delete from Malone Tuning. Used the Rawtek pipes. The EGR and add blue were deleted via the tune. Physically they are still in the car.

@@jackhickerson3022 I was looking at the rawtek/malone delete for the Touareg, like I had done to my Golf. If the EGR is left intact, does the tune just force it to stay closed all the time, so the exhaust gases just go directly from the manifold to the turbo?

@@cbenediccengi That is my understanding. I am not 100% on exactly where things go but the EGR is electronically deleted. Runs SO much better!!

Not much. Only when it’s idling and I’m At the back of the car.

I don’t have one but rear main seal failures are common on the 3.0tdi. Check to make sure it’s not the upper timing covers before you get that repaired. I had an upper timing cover leak and it was an easy job but the oil went down between the engine and transmission and it looked like a rear main seal leak.

@@brandonfriesen5389 you’ve done it with engine and transmission in place? I’m pretty sure my oil leak is from the cover on the passenger side

Darkside developments in the UK.

check this video for list of parts needed for oil cooler reseal - kzfaq.info/get/bejne/qbqehrmftLmYloU.htmlsi=ezNOnzwcoApAHDxA&t=104

Nope. Very happy with how it is now. From what many people have said, unless you go big turbo, there is no point in doing the upgraded downpipe

@@brandonfriesen5389where did you get the kit to block off what is required in order to remove the EGR and the EGR cooler? Thanks

@@thomasfordham4498 this is the kit I bought: www.darksidedevelopments.co.uk/products/egr-cooler-delete-kit-for-3-0-tdi-v6-vehicles.html

Later in the video I show the difference in mileage. Real world, it’s 5-6mpg better

No. It was lemon lawed years back.

Rawetek for the exhaust and Darkside developments for the EGR cooler delete hardware.

Would it be the same for 2013 touareg tdi?

@@sherryshumer5672 yes. Exact same engine code; cnrb.
