Last night after a huge rain storm I went to pick up my son from work and my 1990 Audi Quattro 100, The Anti-lock light came on first, then the battery light and the speedometer stopped working all at the same time. I turned around and drove home less than 1 mile, parked it until morning as it was late. The next morning I popped the hood thinking it was the alternator belt again which is was not. Started the car and it started up but all the lights were still on and took it for a little spin around the block speedometer did not work...I let it run idle for approximately 1 hour before it lost power....If anyone could help guide me with this issue I would greatly appreciate it. Thanks, Nate

The 1990 Audi 100 is on a different platform (C3) than the '92-'98 Audi 100 (C4) that this forum covers. I think you want this forum:
