Well, here I am again, screwed by the great corporate whore. The pump has gone bad at 170,000 miles. This may be do to something the previous owner did. Problem is AMG (American Motors of Germany) won't let Bosch release the parts to rebuild. Can't find one in a junk yard. No parts in Germany. No parts in USA. MB does have new ones they will graciously let me buy for $6,000 and I can use my old pump for a boat anchor. Screw them. Does anyone know where I can get a pump or should I sell this car for parts?
