When I start my C63 I feel a bit of a vibration. When I pull out of the driveway and drive around noise goes away. Although there is a shake and a vibration when I stop in gear. Put it in park or neutral it's gone. But if I warm up the car for 10 minutes no noise. What may be the issue? Recently changed PS pump and running k and n filters if that could be a reason. Thanks

 

Plugs.

Scan the car to be more sure

 

Please do a search, this has been covered too much. It could be anything from motor mounts to a dead squirrel. More than likely it is just the V8 you are feeling. It will shake the car a bit. You will also feel it in the brake pedal every so often when stopped. Nothing is wrong with your car, now go wash it and drive around .

 

a dead squirrel. love it

 

Big V8s always have a slight vibration/shaking feeling. Pretty much ever big V8 I've driven has this feeling. Now if it's severe and persistent and impacts normal daily commuting, then it might be something more serious.

Also, assuming you have a 12+ C63, MCT trannys are somewhat finicky... especially from a stop or off the brake. I can't comment on the 08-11 trannys.
