Hi - the MB dealer just said it was the CVT computer and that they would need to get a new one from Singapore (we are in New Zealand).Your B has multiple computers on board. ...please explain with more details. MB have always run away when you mention CVT problems...or they are always happy to just change your CVT out for you.
There are now shops that do some repairs to the CVT. ..mostly plastic valve body repairs which tend to crack over time. You should go back and read about the many CVT problems in this forum...it's extensive...(Why not fill in your profile ?)
Will fill out my profile.
