Servus , I drive a c230 from 2005 with the M272 . In itself the engine number belongs to the „Risk group to this however I find not clear whether without exception all engines have the material error since there were several suppliers . Does there anyone more ? From 10% of the engines over 50-70% up to 100% of the engines everything is there . In itself I have no problems with the car , had asked me if that is to be 100% or if I could be lucky . Greetings
