C200 K, 2003, 50k miles, in my possesion for about 20k miles.
No problems since purchased (I am second owner) apart from an ignition coil replacement 2 months ago.
Recently engine started misfiring when hot (after approx 75 miles) and engine warning light came on. After cooling down started and run smoothly. On my return journey similar fault occurred. After cool down ran OK.
Went to my Service garage (not Mercedes but switched on guy with all Bosch equipment). He found that one cylinder was down on compression when hot, (same cylinder which had coil replaced).
My man thinks it is either faulty piston ring/s or valve seating, and may be aknown Mercedes fault on this engine.
Anybody out there had a similar problem?
