Here is the latest: Found that the ASR/ESP charge pump was seized. Took it apart and got it working on the bench. It appears it is NOT getting 12 v from the controller. I am only getting about 1 v from controller to pump. My question is, when you first turn the key on, should the controller supply 12 v to the pump or under what conditions should the controller be providing power to the charge pump. Before I condemn the controller, can someone help me out with this question? Thx

The EPC shows a relay for the ABS (part #167), but it doesn't show where it is located on the car. Could this relay control the pumps?

Good point !! Hopefully someone will chime in if they have any other thoughts.

I'll bet Arthur Dalton would know.

Feel free to point him in the direction of this tread, as I am at a standstill unfortunately.
