Exhaust fumes in the cab

Hey guys, I'm really noticing exhaust fumes sucking into the cab through the fresh air ducts when the car is idling (stop light, warming up) however when the car is moving, there is no problems! New gaskets on turbo, not sure age of exhaust system though! Any ideas? I thought maybe cats getting plugged, or the flex section is deteriorating?

I would get a small mirror and torch and have a little look around that egr pipe for any black sooty marks, also worth checking the ccv too as the engine fumes from it can smell similar sometimes.

If they both check out then I would suspect the flexi on the down pipe. Mine looked fine but it was definitely leaking and I also got a bit of exhaust smell once in a while when stopped.

My 2004 Jetta has the same issue. The bracket was missing. You could see the black soot at the cracked area looking up from under the car. After 3 new pipes at the dealer, I looked the issue up and found a recall to replace the egr cooler and add a bracket. Called the M6 EGR Campaign. The large steel bracket on the cooler was cracked from not having the bracket which caused increased strain and vibration to the egr pipe. (I didn't have time to look, that is why my wife to dealer to get fixed. Prefer to do myself.) Then spoke to dealer about the missing bracket, they had NO clue, I sent them the bulletin and then they fixed it properly. Charged me $235, don't know if they should have charged me anything, egr cooler price is higher. Then the MAF sensor got contaminated and had to change that out also along with the new air filter that I just put in.
