The anti-lock brake system (ABS) control module may fail causing the ABS light to illuminate. Failed modules should be replaced to restore ABS operation.

ABS, parking brake, brake & tail light warnings intermitently at first, now constantly. Dealer quoted $2500 to "start" repairs by replacing the ABS module, then see what error remain. In essence they told me they will start replacing parts one at a time until the problem goes away! First and last Audi I will ever buy.
