Bad motor mounts can result in a vibration across several hundred rpm. Usually felt at the lower range. On mine it was ~1300-1800 rpm. A borescope camera can be used to inspect the mounts. One of mine was obviously collapsed and wet from the fluid leaking out.

Example of bad motor mounts on my W210...



On my W211 the motor compartment is much tighter so I had to use a borescope to see the collapsed motor mount. I did not, however, keep the photo...
