My ABS, brake and oil lights keep coming on at the

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)
