I have 2 pumps 1 from a jetta and 1 from a passat, just need to test them, let me know if you are intreasted.

 

confused... i have a 98 audi. pump stopped working so i bought a used one from a 96 model and everything works now except the motion sensors arent working anymore and the led lights arent flashing anymore... is this because of the pump. its the same part number except for the last letter my car had the newer version...
