All of a sudden my ABS light came on in my 1999 audi a6, and the brake light started flashing. I had a full loss of my ABS brakes on icy winter roads. I eventually slid off the road and hit a fence. The ABS control module on my car had failed, and I've read posts of several hundreds other having the same problem. In my car it is a constant error, and no-one but audi can fix the problem. I also contacted audi, which claims that the ABS system disabling is not a safety concern. When there's a chance that your ABS (something you've relied on for years) suddenly shuts down because of a way too common error, it is a major safety concern. I was lucky I only got some dents to my car, but if audi had recalled these I wouldn't have had to get repairs done to my car. Unfortunately someone will probably have to die before this safety concern is taken seriously and audi will do a recall.

I drive a 1999 audi a6 avant which is our primary family car. While driving the car one day, the car's ABS warning indicator light comes on and stays illuminated until the car is shut off. At the same time the red brake warning light flashes on and off until the car is turned off. This same thing happens every time the car is turned on. Despite the flashing warning lights, the brakes operated normally on dry pavement. However, on wet, snowy pavement the ABS did not work when braking for a stop. I called the audi dealer to make an appointment for this problem (and other issues) because I was concerned about the safety of the brakes especially during the winter. The person I spoke with at the audi dealership did not sound alarmed or very concerned about the warning lights for the ABS and the brake. I asked again about the safety issue, and the person said I would be fine and made an appointment for me for two and a half weeks later. We drove the car carefully for the next two and a half weeks until our appointment at audi. Before even looking at the car, audi service desk said that the warning lights were probably, more than likely the ABS control module. I was told it would cost $975 to replace the ABS control module. I didn't have the dealership replace that ABS module yet because I needed other repairs first. After researching the ABS control module online and after talking to a few people I realize that is a very common problem for this make and model car and for other audi cars but there is no recall campaign in effect for the batch of faulty ABS modules. I live in minnesota where there is potential to be snow 5 months out of the year. I bought this car used because of all the safety features that are useful in snowy weather. To have the ABS not functioning properly and then to realize that this is a common problem in this make of car seems to me to be a safety issue that should be addressed by the manufacture. Audi should recall the ABS module. Thanks.

Abs light stays on.. Took to dealer and they said faulty control module..$@$1000.00 to repair... Was told that this is a common problem with 1999 audi a6 avant...also was told that this problem almost never happens on any other automobile...checked on the internet and found many audi owners have had the same problem..why should we pay for audi's faulty components?
