Hello,
I have a 7 years old A4 B7 2.0t with about 135,000 km on the gauge and recently I developed a weird problem. It seems that my left exhaust pipe blows little but noticeable more smoke than the right one, plus the sound is little bit louder coming from it. I took the car to a service shop, and they visually inspected the exhaust pipe after raising the car, but they didn't see any problems.

Any suggestions/ideas if this is relatively normal?

Hopefully, this is not a beginning of a major problem.

 

lol. don't worry, my friend.
