Just joined, my gal pal just purchased a 2000 a6 Quatro, WOW what a car. Brake ABS lite on, Could it be that the brakes just need bleeding? The code states that the fancy brake pulsating module has failed. PO had new pads installed, I have no history for the car. Could replacing the pads cause an errant reading for the code that a proper bleeding would cure? I have a motive bleeder but would need to acquire correct M/C adapter, but I thought these systems need something more advanced. Also have a Question regarding the timing belt, 101k on engine, should I be looking at replacing the belt as preventative maintenance?. Your comments will be appreciated. Thanks T

Terry, welcome aboard.
See if you can find your local VCDS (Vagcom) person and have them read error codes for you. It's entirely possible it's something simple like a dirty ABS sensor or a failed ABS sensor. Not likely to be related to brake bleeding.
Any documented history of the belt being replaced?

Welcome!
My first suggestion is not to try to bring that fairly old car to a perfect condition. It would be very pricey and it would never pay back. That doesn't mean not fixing essential things.
ABS wise, which scanner gave you that code and can you be more specific what it said. Unfortunately bleeding won't fix anything. Have you tried if ABS is working?
Timing belt wise, you didn't say which engine it is. Depending on that it can be quite a job to replace TB. It is generally very difficult to say if it was replaced if you don't have any documentation. If it is not replaced it most certainly should be.
P.S. You can get more information in that model/year forum.

I used to own one...
A 2000 A6 4.2. If I follow your post right, it sounds like your ABS module is bad. It was a common problem on that generation of A6's as well as other model Audis. The electronic module portion of the ABS unit can be separated from the hydraulic portion, and is basically just a few screws plus pulling off the harness connector. There are places you can find on line who repair them--IIRC it was a simple bad solder point or some such. Do a search. If I remember right, you can just pull yours and send it in. Because the hydraulic unit is still there, I think you can still drive it. It just doesn't have any ABS function, probably same as now if it has died. Year 2000 Audis are before they started the security coding on a variety of modules too, so no special dealer visits required.
Yes, if belt has not previously been replaced, it's time. V6 and V8 belt tools are basically the same; V8 is a tight fit but I did it myself twice. The V6 from my older 1996 C4 A6 was a lot easier, room to work wise.

It's a 2.7 v6. Are they single or dual overhead cam engines? After looking the engine over I did notice the some missing bolts that secure the aluminum pipes to the front of engine, suggesting some work up front. No ABS function. Will find out about the codes. Thanks T

Unlikely that its simply pads. The ABS module does fail occasionally. You should also check abs wheel sensors and wiring.
I would get the codes pulled - best to invest in vag-com ( ross-tech)
