Check cracks on exhaust manifold

 

[Singh]

Seems to be a common issue with diesel Touaregs, especially when they get old.

Egr pipes and cracks in the exhaust manifold seems to be the issue contributing to the foul air which goes into the cabin

Well my v10 has this exact issue as well now. Wondering if its the egr pipe or cracked manifold.
Mostly on cold starts, but i think it will deteriorate in time.
A mate with a t2 v6 had t really bad, was most of the time but he sold it

My wife has been complaining about a very noticeable exhaust smell immediately after starting the Touareg when it is cold. Once moving nothing can be smelled. Then once warm nothing is detected at stoplights.

I used a flashlight and could see some light smoke coming up from somewhere behind the passenger side of the engine. What is back in that area? Any ideas on why only on a cold startup?

depends how cold, if lower than 4c then could be webasto, else exhaust manifold, etc etc

I have been having diesel smells for a few years now. Do you know if this is affecting later model Touaregs, in particular the MY16 V8 TDi.

You get that in your 7p?
Didn't there was any issue with 7p at all.
I have had no issue at all, but the issue is not uncommon on 7L models
