Oil leaked from a faulty seal & wicked into the control module. Could not get a rebuilt part from MB, so installed a new one. Price tag: $1900.00. Also have very dangerous issue with BAS/ESB system. Looks like the Navi unit has a short, causing the benz to think it is encountering a hazardous road condition. It brakes and swerves itself, which is really bad when you are in traffic. Frightening.
