One problem related to brake abs warning light has been reported for the 1999 Audi Quattro. The most recently reported issues are listed below.
The abs light comes on intermitently. It will come on, beep 3 times, and then flash for a while. It will stay on for some time, and then turn off. This problem has no relationship to when I'm moving or stopped. The abs light may turn on or off an an time. And when I try to connect with the handheld diagnositc system, it fails to connect and give an error code. Occasionally we have gotten some obsure error messages about a dash connector failure, but ususly we cannot connect with the handheld unit, or pc. I've been told that the brake should still work, but that the back breaks may lockup.
