My abs light started blinking in my 1998 Audi A4. I went to a mechanic and had it diagnosed; found that it was a light failure; I was told I would have to pay a lot of money to pull out the electronics and most likely not even solve the problem. Later I started to notice that my abs was not engaging properly and sometimes not at all (which is now the case), I filed complaints with Audi and boshe about this but they told me there could be no recall because abs is not a traffic concern. Recently I was driving in the rain and making a 98 degree turn not terribly fast; there was no stop sign, and I ended up doing a 360 to a stop. I found this not only a scary experience, but one that could have been life threatening. It didn't make sense; im driving the honorable quattro. I decided to look further. I found many people have the same problem. Specifically w/ models in 1998. Im a fairly good driver in fact I did a defensive driving class at infineon raceway so I was still confused how I lost so much traction in such a short amount of time. I found the problem was actually part of the quattro itself. The electronic braking, traction systems, and various other vehicle dynamic systems are all dependent on the abs control module. All the test up to then showed no link to abs control unit; I was made to believe that my car just had a light failure. I started researching the control unit and I found that there is already a recall on the part but not for Audi but for Volkswagen! the campaign id number is 02v031000. I talked to people who were owners of volkswagens who got the recall and many of them had almost identical problems to mine. Some even said the unit caught fire. So here I am told I have a light problem, then told Audi cant do anything for me except get a whole new abs system at my expense. Now I find the truth is one control module is responsible for the lack of control in my car as well as a possible car fire. Please help: I and many others need a new unit.

Failure of abs module, 1998 Audi A4.

Iã‚m an owner of a 1999 Audi A4 quattro with the 2. 8 engine; the VIN of the vehicle is waued28d0xa238672; 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 donã‚t 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 804031021. 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 driverã‚s aide. Additionally she could not find any records that showed volkswagens being recalled for the same issue. I eventually got a problem fixed at a smaller shop, which cost me around $600. 00 dollars. The dealer was going to over charge me on the part by $400. 00 and 6. 5 hours of labor at $105. 00 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.

Control module is completely inoperative most times while driving. May start working sporadically and then quit again. Common problem on forums (audiworld. Com). I have been a vw / Audi technician for 7 years now and have seen several of these. Would be nice to know that this safety feature is going to work when needed. Vw / Audi is aware of the problem and has just released a technical bulletin alerting that the control module may now be purchased separately from the hydraulic unit. This control module at my cost (considerable discount since I work for the company) is $1495. 00. Please help myself and other Audi / vw owners get our cars stopping safely.

The abs control unit on my Audi A4 failed after only 67,000 miles. I have no anti-lock braking whatsoever, and Audi has denied any responsibility for the part since it is out of warranty. Searching through Audi forums I found this failure to be very common and everyone had no abs until the control unit was replaced which cost an average of $1500+. There were no events that lead up to the failure, I started the car one day and the abs and brake light started flashing on my dash. I tested the abs on an icy road and found that it indeed does not prevent my brakes from locking up.

I experienced failure of abs in a 2000 Audi A4 avant quattro. This is the well-known and widely reported problem with the bosch 5. 3 abs control module unit. The unit spontaneously failed without any reason, at about 80k miles. The consequences are the abs does not work and the part to replace it is about $1500. I have yet to replace or repair it at this point, hoping vw/Audi will do something about it (a recall would be nice).

Audi dealer diagnosed as a abs control unit failure with part cost of $2600 plus labor and was repaired by Audi dealer. Contacted Audi customer care and they did not offer any assistance. This is a very real safety issue and based on internet searches has affected hundreds of Audi and vw vehicles. This appears to be a faulty design of a critical safety component and warrants further investigation.

I'd like to file a complant for a faulty vehicle component on my 2001 Audi A4 (mileage: 30,000 miles). The abs and brake warning lights are coming on simultaneously. I've been reading a lot of similar complaints on the internet (that's how I found this site). Dealer says there's a "fault code in the abs control module". . . And wants $1500 (!) to repair it. The abs unit should not be failing as frequently as it seems to be in this car. For a $1500 component to malfunction when it's rarely actuated is beyond comprehension. The TSB should force Audi to perform a recall and/or compensate customers for this outrageous problem.

Abs module/sensor failure. This problem occurs frequently with other Audi owners and has been thoroughly documented on sites such as mycarstats. Com. Basically the abs and brake lights would come on while driving, accompanied by a beep. After initial research, I was able to confirm the module had failed and would require replacement. Local Audi dealer quoted 1500 for the module plus labor. Luckily, I found an alternative by sending the faulty module to modulemaster. Com. This company specializes in repairing defektive circuitry. The labor is warrantied for the life of the vehicle and costs 300. 00 (including shipping and misc. Stuff). The car was still driveable while the module was out. Their website contained a video on how to properly access the module, remove it, and replace it once it was repaired. All in all, I saved myself '1200 plus labor'. I would like express my disgust with all Audi dealers who sell their modules for these outrageous prices. One thing none of them admitt to is that the reason why these bosch modules fail is because of a known defekt in the circuitry. So their $1200 modules will eventually fail too.
