Hello Everyone,

I know we have covered this topic a few times I think we are all aware of the engine issues certain earlier 06/07 Q7's had resorting to engine swaps for many.

My concern is, I am on my second engine and the same "cold start" diesel, clunky starts are still present. These were earlier signs of serious problems down the road the resulted to my engine replacement at ~16K.

I brought this up to my dealership and they assured me backed by a TSB 201294/5 that this is "normal." Vehicle runs well, I will say this!

Are your vehicles still making the same noises? I know there has been a few reportings on "cold start" noises gone on 2nd/remanufactured engines and how are you Q7 performing?

Thanks for your reply!

I am amazed that a replacement engine is doing the same thing... and so soon.
Please keep us updated.

If anyone else chips in with engine replaced I will update.

I'll keep everyone here posted. Also, anyone with a vehicle buy back please post. As I came accross an individual last night that went through this.

Again, as I mentioned my Q7 is running great so far, it's the cold starts that are worring me...

Thanks for the update. That makes two 4.2 but very different reasons to 3.6
