ABS woes, again

Post by Clemens »

So for the second or third timw this year the ABS and TRACS light came on. I soldered the module 4 times in the past 5 years and the problem seems to come back.

Since I have a 96 I can't blink out the codes. I know that theoretically wheel sensors, the wiring to the sensors and the ABS rings could really go faulty. But over the years it were mainly the modules. I know the wires to the ABS pump are crappy, but I don't know how the remove the pump.
Now honestly, what xould I do to get that stupid ABS system to stage 0?

If you can find serial db9 to OBDII cable(Vag-Com kkl) i can send you Vol-Fcr via email.
Other than that...you can remove and clean out front abs sensors because....since they are magnetic...they can be fouled up with metal debris from pads and rotors.
