Since i bought the car, second hand by the dealerschip (about 1 year ago, with 55000 Km on the clock) I've a problem that, as per MB technician is not a big worry.

Mine is a manual C200 Kompressor.

Revving in neutral at about 4500 5000 rpm (but during cruise otherwise engine limiter cut at about 3500 4000 rpm) I hear a rattling noise sincronized with the engine rpm.

MB technician say that it's from the exhaust and it's not a problem!

Please do You have some similar experience.
