Having problems with your 1999 Volkswagen Passat ?

My ABS, brake and oil lights keep coming on at the same time, flashing for a few minutes and then going back off. This happens very randomly, sometimes lasting for seconds, sometimes lasting for up to 20 min. It doesn't seem to matter how long the car has been running. Now the tach is also dropping to zero as soon as the other warning lights come on and remains there until the lights go back off. Any ideas?

Answers :

Its exactly the abs module! and its keeping the ecu from communicating with the rest of the car, when you remove the module your tac will come back alive and the oil light will turn off. There is way to trick the ecu to thinking the abs module is working but it involves taking out the module, it is fairly simple. My email address is [email protected], email me, and I will give you pictures and instructions on what to do. Its really easy, your abs and break light will go off along with the beeping!
Thank you "capitolauto" I had exactly the same problem with my 99 passat , and it eventually became permanent instead of intermittent. I consider myself a good mechanic , but I was stumped. Even my buddy who works for VW wasn't sure , he said it was a ground problem somewhere. For those of you with 2.8 L VW's and Audi's If your oil light and abs light come on intermittently , and your tac quits working , apparently the problem is the ABS module , and Modulemaster.com has great instructions for removal (even a video)
