I have received this part twice, with diff. part numbers.
The parts are identical, and they don't fit.
The leads are too short.

This lead/length problem seems very strange.

I can't understand why MB or Behr would make a part with leads too short
to fit the original application.

I wonder if these are Jap or China parts with counterfeit Kraut boxes--fakes, with the part and the packaging made to look like the orig. MB part ?

...or has socialist Germany deteriorated so much that it just doesn't give a damn ?
