I found the gearbox was slipping (no wonder after 300k kilometers) and replaced it. And … the problem still exists. Maybe it is the SC or maybe the injection? I read somewhere that sometimes the relais box is the problem and can cause all kind of problems. The computer does not complain about anything by the way!

Does anybody know:
the OEM number for the relais box?
know whether the box from the SLK 3.2 AMG is the same?

well …I only spent only one year until now and built myself a better car in the mean time. If I can solve this then I’m done 😅
