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.

Started having intermittent ABS Brake and Brake (Blinking) and Sound from time to time.
Had car into Audi they said the Brake Fluid was low. Problem went away. Problem back went
back to Audi they said there is a leak in the Vacuum Module that needs to be replaced and
a few other items. $850.00. Now, still have the Brake (Blinking), sound, and ABS light then
Check Engine Light on. Took to Audi they said the ECM module needs to be replaced $1,700.
Before I got it off the lot the lights back on. Now they say it was to do with the ABS brake
module.Flag ThisLike0 -

ABS light has been flashing since I purchased the car about a 1 1/2 years ago. Didn't bother fixing it though.
