Eight problems related to brake antilock control unit/module have been reported for the 1999 Audi A6. The most recently reported issues are listed below.
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.
