One problem with all German cars is the soft rubber mounting for the Bosch
Alternators. This rubber mounts usually deteriates over several years, leading
My solution was to cut some poly-urathane bushings to replace the rubber one.
Below is the bushing.

The proper Voltage Regulator for this alternator is:
Alternator Speed = 2.4 times crankshaft speed
