Does anyone know what MBUSA position is on the potential for serious carbon buildup on intake valves with the new cgi engines? I have read horror stories of how this is a serious problem for other manufacturers of cgi engines. Is this something we will be able to prevent or will it simply be a non-warranty expense that we can look forward to?
I'm planning to buy a 2012 E350 but have some concerns if I'm buying into a reliability problem that doesn't yet have a solution.
Maybe someone from MB can give us some information to reassure us that it is not an issue with their engines. It would be irresponsible if they know there is a problem and we are going to let us suffer the consequences.
