Air Brake Antilock Control Unit/module Problems of Audi A4

I have a 1998 Audi A4 avant, 2. 8 v6, manual transmission. After 45k miles the cruise control module ("brain") failed and had to be replaced. At 91k miles the abs brain failed. Was there, or will there be, a recall on these items?.

Normal driving conditions, no modifications to vehicle, at 80k miles the anti lock brake module fails and the abs no longer works. The brakes are prone to locking up. The replacement part for the vehicle when out of warranty is $1200. I have been driving it as little as possible until I can save for the repair. Additionally, the cruise control stopped working out of the blue at 55k miles. This module has not been replaced either due to cost.

Abs control unit on my 1998 Audi A4 failed as I was driving on the highway, total brake failure resulted, in which I was only able to stop via the triptronic transmission which allowed me to downshift, and finally using the ebrake. . . Called Audi of America, they told me that their shouldnt have been total brake loss if the abs unit failed, which made no sense since the pump was spewing brake fluid all over my engine. . . I assured them that it was a safety issue, and that Audi should be responsible for its repair, which runs in the range of $2500. . . They told me that that shouldnt have happened, and because of the high mileage on my car, they werent obligated to repair the problem, even though thousands of Audi owners have complained about the same problem. . . I believe Audi should be directly accountable for this mechanical defect, and issue a recall ASAP, before other Audi owners experience the same scary ordeal I did on the highway. . . Thank you.

Abs computer failured during hard braking. After searching car sites, it appears that the vw/Audi abs units regularly fail rendering the abs inopperable. Although the regular braking characteristics of the car are maintained, the abs no longer functions. Having this fail during a panic stop could have caused a bad accident. Thankfully I was able to figure out that the abs unit failed (due to the beeping) and correct accordingly.

Failure of abs controller in 2001 Audi A4 1. 8t. Was told by dealer that engine heat melts soldering in unit. $1,300 estimated repair ($1,000 for part alone). Intermittent failure light and beep when driving, abs not active when light is blinking. I've read on Audi websites that this is a common failure that Audi of America refuses to take steps to rectify either monetarily or through redesign of the controller to prevent future failures.

After only 65000 miles on my 1998 Audi A4 I have been forced to replace major abs components because of numerous failures. The abs system works intermittently, and there is no indication of when it will fail. A brake light will come on, then go off, indicating there is trouble, but at times the light will be off and it is not until you begin to brake that you realize the abs is non-functional. Audi has been very slow to repair the problem, requiring a 2 week wait just to diagnose the issue. Then requiring $2300 to make a 6 year old car safe to drive.

The abs controller failed. Numerous other owners have experienced this possibly safely related failure. This part controls the abs braking and if it fails, the abs does not work. This could result in crashes due to drivers expecting abs support during hard braking only to realize it is not working. Some owners have had this fixed outside of Audi warranty and we believe Audi is running a silent recall. . Read more...

Abs control unit has failed on 1998 Audi A4 quattro 2. 8. This ~$2000 part raises a significant safety issue, as its failure results in loss of abs braking and traction control.

Abs unit failed on 1998 Audi A4 2. 8l quattro. Repair cost is > $2000 for a rarely used electronic module.

My abs and brake light initially came on intermittently, then began to occur more and more frequently. Now it happens every time that I get into the car. My abs does not work. A loca Audi dealer told me that this is a very common problem for this year of car. The dealer told me that I needed a new abs control module ($1100. 00) and three hours of labor at $78. 00 an hour.

Picked up car at holberts Audi in warrington, PA on June 15, 2004. Dealer replaced right fron upper and lower suspension links. After leaving the dealership, the abs light came on and the brake light began blinking. Brought car back to dealer and dealer said abs control module needs replacing. Without a functioning abs control module, the car is without the increased safety provided by anti lock brakes. Haven't replaced the part yet due to its $1,000 price tag.

During routine commuting to and from work the abs warning light comes on intermittantly. A diagnosis was performed and revealed a failed abs control module, rendering the abs system inoperable. The cost of repair is estimated at $1500. The failure is attributed to faulty engineering in the oem part as this failure is very common with this model Audi. The consequence of the failure is ultimately an unpredictable and unsafe braking system as the abs system now works sporadically then fails completely. The part has not been repaired at this point due to the exuberant cost.

(1) faulty design of abs controller, 2) failure of said abs controller, (3) abs no longer functioning, causing a safety hazard.

Our abs light came on the day I picked up the car from the dealer after getting all new brakes done. Bernardi Audi of natick MA. They refuse to believe they are to blame. (whatever) my independent mechanic is saying the controller is dead. This car is a 1999 Audi A4 quattro that had 65,000 miles on it when it died. The car runs without abs to this day. I can't believe they charge 1500 dollars to fix this!!.
