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.

The abs control module needs to be replaced at a cost of $800. Literally thousands of these modules have quit working on 2000 Audi's. A visit to the internet displays so many complaints regarding this part that there is not time enough to read them all. Audi not only refuses to recall this part (since no one dies in an accident because of it) but they also refuse to document your complaint to generate a list of complaints regarding this part. I first was told I had to go to an Audi dealer to have the malfunction validated (a private auto repair shop would not do), but after I paid Audi $60. 00 for a diagnostic, Audi USA still could only tell me that there had not been a recall and maybe the dealer could do something to help me.

Audi A6 abs not functioning after only 58,000 miles. Audi refuses to stand behind its engineering and repair. Diagnosis" abs control unit is no longer communicating with the instrument cluster". Cost over $800 to replace and can only be replaced by Audi dealer. Many A6 owners have same problem, yet Audi has not issued a "campaign" / recall. Isn't abs intrinsic to the safety of the car. . . Sort of like the airbags? why not engineered to last longer than 58,000 miles? or, could it be engineered on purpose to generate dealer service revenue? something not right here.

I own a 1998 Audi A6. This vehicle has been driven approx 75 000 miles. Several months ago the abs control unit (brakes) failed. I was quoted a price of $1085 by the dealership where I purchased the vehicle. There are no used parts available. When I made an appoitment to have the unit replaced I was informed that Audi no longer manufactures the origional replacement part at a cost of $1085. Rather, Audi has remanufactured the replacement part and the new cost is approx $2000. 00. I verified the cost of the remanufactured replacement part by calling a few dealerships. My complaint is that I believe that Audi recognized that the original part was defective and that once the abs control unit failed it made abs braking inoperable and therefore unsafe. Rather than recall the 1998 A6 to replace the defective abs control unit, they allowed consumers to either drive with an unsafe control unit that could fail at any time ot pay almost $2000 to replace the defective part.

Vehicle is a 2000 Audi A6 with 2. 7t engine. Ileage: 52000. Failure: dealer diagnosed abs/controller was bad and needed to be replaced at a cost of $1300. 00. The problem causes intermittent abs failure which will pulsate brakes occassionally in situations where braking would not require abs activity (ie. Light braking to slow vehicle slightly on dry pavement). This could slow braking response and increase chances of an accident occuring. This problem is commonly discussed in Audi user forums and appears to have a fairly high occurence.
