ABS light on Codes indicate a faulty valve, Pump or Control Unit?????
ABS light comes on in my '95 M3 w/ 72K on it. I read the codes and it says faulty valve. I take it to the dealer and they say faulty valve, BUT want to put a new control unit in first ($950) my cost plus labor. How often does a ABS control unit go bad?
Now I'm getting info that the pump is the problem. Another list member said he had the same problem and took the pump out, put it on a bench found out there was a bad connection at one point on the board. He resoldered it and Viola, end of problem. One would think that if you have a faulty valve code that it has a real good chance of being in the pump somewhere. I know that's not a sure thing, but if I fix the friggin' control unit and it doesn't fix my problem guess what's next. So do you have any source for a pump in good condition or confirmation that the above experience w/ the pump is on target?
TIA
