BMW ABS - ATE 6765452 - What goes wrong in this abs pump ?

[bursuc]

I got a Bmw e46 abs pump ATE 6 765 452 - 10.0206-0026.4

Something goes wrong with it . is not communicating at all.

i know that on Bosch , the aluminium wire goes faulty but on ATE is different design . wires are not a problem anymore.

Thanks for any advice . best regards
