2000 Volkswagen Passat 4 cyl Two Wheel Drive Manual 140000 miles
I have a ABS light on dash with a flashing brake light. As well, there is a message on info display screen running constantly w/ message of Stop. Brake Fault. Service Manual. Repeating.
Brakes work fine when driving and there is very adequate pad life remaining on all four wheels.
My question is regarding installing a replacement ABS Modulator Pump. The VW recycler whom I know and trust found a replacement on E-Bay Motors that is the correct match for my Passat. He indicated that replacing this ABS MOdule would require some bleeding of brakes as well as replacement. When I went to my auto repair shop I mentioned what the recycler had said regarding the need to bleed brakes as part of ABS replacement and the mechanic siad this was not true. It is in fact four bolts/screws holding it in place he said and he said the VW recycler either lied to me or did not know what he was talking about.
So, who am I to believe? And, what is the correct procedure to replace this ABS Modulator Pump.
By the way, my OBD II scanner pulled a code of P-1113 which I could not find in my book of codes. I assume it is VW specific. Is it the code idicating fault in the ABS Brake system?
Also, the VW recycler did hook up his VW scanner to help me diagnose the need for a replacement ABS Module. He said 90% of the time this is the componet that fails.
Engine is the 1.8 Turbo and car has 140000 miles and runs great.
Thanks in advance for your help and I am happy to donate for your expertise in the matterl. Steve
