I bought the 2005 Audi A6 used, as soon as I left the lot about 1mile I got parking brake fault message with abs message. still comes on every time I drive the car. Have not had it repaired yet. Update 6-12-2014, Just had my ABS Control Module serviced from a independent repair person that did find a fault in the Module I reinstalled it and not had a problem since, (it has been only 1 day so far but way happy that I don't get that beep or message anymore) . Cost about $200 for the fix and about 1/2hr total time to remove and replace, Dealer wanted over 2k.

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.
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.
Break lights stay on while driving and when I cut the car off
ABS light has been flashing since I purchased the car about a 1 1/2 years ago. Didn't bother fixing it though.

Bought my car used and it had ABS/parking break fault. they cleared the codes and it came back. every time i get in my car the faults come up and beep while i drive. Audi dealership wants $2000 to replace the ABS system but i dont think that is the problem. I think it all has something to do with the EMC. Have not fixed the problem yet

Haven't fixed this yet, but my ABS light on the dash is on. There are about a zillion videos on line of how to fix this without replacing the whole module, though: commonly, one of the connectors will break, and it's a simple matter of filing away the protective plastic, soldering on a little piece of wire to bridge the gap, and covering it over with epoxy.

ABS light solid, brake light blinking. Had scanned, scanner could not communicate with it. Thought I read that was a good thing. Haven't tried to fix yet.

Purchased year 2000 Audi Quattro A6 in Feb 2013. ABS Light was coming on when purchased. At first it would come on as the engine warmed up. Now in the heat of the summer it comes on at startup. Was told it would cost $800 to replace. Have not fixed.
