Strange Noise 2012 335i
YouTube link above to my video (didn’t know how else to share it) I also heard this noise on a 135i (w/ n55) that I saw. Every so often there is also rumbling that can be felt in the car and heard from the exhaust. In the picture you can see some sort of soot? Or carbon that was found right below the exhaust. It’s been a few n55 cars that I see having these, what is the issue? Wastegate rattle? |
