Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** you tell me if the vibration is any different when accelerating hard to slow acceleration? Does it stop right when you let off of the accelerator pedal?
Thank you. To answer your question, yes, this is almost always a drive shaft issue. The coupler becomes worn and this occurs. It can also be caused by a bad engine mount. One other thing I have ran into on this vehicle is a programming issue causing the transmission to shift at the wrong time, but that is not as common.
