hmm, this looks like mine! went through hell trying to replace the , oh, crap forgot the word-bushings?? clearly visible on the picture (support the shaft). they are made of soft metal and are supposed to wear out. Talked to the Bosch tech. You should replace the whole thing because the wiring thins out and you cannot buy the right part. $99 from Germanstar.net. Pain in da.. to get to on a 190 (took me 4 hours the first time, can be done in 2, access to 201 chassis is from the engine compartment).
