The ABS module on my vehicle has failed. This problem seems to be quite prevalent amongst Audi and VW vehicles. An ABS failure could cause accidents and deaths. This module should be recalled. The problem begins with three beeps, a solid yellow ABS light and a flashing red brake light. The warning may come on momentarily while I am driving and go away, but in most cases will become more prevalent as time goes on. Sometimes the ABS and brake light remain on. Occasionally the ABS activated (in other words ABS braking has activated) while the car is in motion. From researching this problem, it seems to be common with Audi A4 and VW passat B5 models. The ABS warning light will come on each time the vehicle is operated. The sudden ABS activation will occur rarely. The consequences of sudden ABS activation is obvious; braking when not expecting it can cause tragic results. Losing the ABS functionality while driving and when it is needed can also cause tragic results. I took my car into the shop. A vag was hooked up and the following code appeared: "01203 - electrical connection between ABS and instrument cluster" replacing the electrical connection between the ABS and instrument cluster will not solve the problem. The only resolution for this issue is to buy a new ABS unit, buy a used ABS unit, or have the current control module rebuilt. Again, systematic and widespread failures of the ABS control module are occurring. Numerous owners have filed complaints with regard to this issue. Please look into the issue and consider recalling the module before it tragic results do occur.

I am an owner of a 1999 Audi A4 quattro with the 2.8 engine; the VIN of the vehicle is [xxx]; the vehicle has 101,845 miles. I was having the following issue; at about 100,000 miles the ABS and brake warning lights would come on indicating and ABS failure. This would occur after the car is completely warmed up. I did some checking and discovered that there is problem with ABS control unit. I further investigated this issue and also discovered that this is a known and common problem with 1996-2001 Audi A4S. Volkswagen jettas and passats of the same year, that utilize the same system, had/have the same problem; it came to my attention that Volkswagen conducted a national recall campaign to address this problem. I was wondering why Audi has not handled this problem in the same manner. I dont think Audi owners should be expected pay to fix a clearly manufacturers defect, and a safety component at that! I contact Audi customer service to get a reaction from them; the reference number is [xxx]. I wrote a detailed letter to Mr. Johan denysschen executive vice president Audi North America; he in turn passed the letter to one of the Audi regional managers annette johnson. The regional manager had indicated that the issue should be diagnosed by an authorized Audi service center (Audi dealer). Her tone was very helpful; however she has indicated that there have not been enough complaints to constitute a recall. Furthermore, they do not consider the ABS failure as a safety issue since they regard the system as a driver''s aide. Additionally she could not find any records that showed Volkswagen being recalled for the same issue. I eventually got a problem fixed at a smaller shop, which cost me around $600 dollars. The dealer was going to over charge me on the part by $400 and 6.5 hours of labor at $105 per hour for a job that actually took only 1.5 hours.

Audi A4 the ABS light, brake light and warning buzzer stay on while driving the vehicle. Brought car to dealer and was told the ABS module is defective. Audi said it was not their problem because the brakes still function though not the way they were designed to work. I pray that I do not hurt anyone while I'm relearning to drive my car without the ABS system functioning.

Our 1999.5 Audi avant quattro VIN[xxx] has passed 80,000 miles. The antilock brake system (ABS) controller has failed causing intermittent failure of the ABS system. The result is inconsistent and dangerous handling of the vehicle in low traction conditions -- the very conditions Audi quitter's are purchased for! repair of the system is in excess of 25% of the value of the market car. A search of several internet Audi sites revealed that this is a common problem with many current Audi models. Audi of America refuses to fix this problem under recall.

ABS pump failure. At approx. 71000 miles, the ABS controller/pump failed on my 1999 Audi A4 1.8T quattro. There are many others that I have spoken to and read about who have also had the exact same failure with the same ABS pump/controller. tech.bentleypublishers.com/thread.jspa?threadid=3409&tstart=0 and forums.audiworld.com/A4/msgs/1743701.phtml. apparently, Audi knows about the problem but is not widespread enough to issue a recall.
