Abs computer out. From people I have talked to it's a frequent problem in these cars. It is quite expensive to replace.
1998 Audi A4 brakes complaints
Page 2 of 5: complaints 11 to 40 of 125, newest first, as owners wrote them.
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.
Failure of ABS module, 1998 audi a4.
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.

1998 manual audi a4. The temperature was 32 degrees f or below. The conditions were steady snow and wet/icy/slush roads. I experienced complete break failure when exiting the highway to a rest area. I pumped the breaks and regained some breaking power to finally slow the vehicle. I completely missed the proper exiting lane due to lack of breaking. No injuries or damage resulted. This is not the first incident of loss of breaking power.
Abs warning light intermittent. Research uncovered the fact that the ABS controller in the audi and vw passat is faulty. Audi customer care has replaced the ABS controller for other customers. See this discussion thread http://tech.bentleypublishers.com/thread.jspa?threadid=3409&start=0&tstart=0. If this article\ad (http://cgi.ebay.com/ebaymotors/ABS-bosch-5-3i-ABS-controller-repair_w0qqcmdzviewitemqqcategoryz111105qqitemz4601089179qqrdz1qqsspagenamezwdvw) is true and the problem is a cold solder joint then it is truly a manufacturers defect. Please investigate.
Audi a4 ABS malfunction. 1998 2.8 liter quattro.

Abs control modules (bosch 5.3) on all early model 98-01 audi a4 and it's sister car the vw passat 98-01 will and do fail at some point. 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.
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?
Dt: the contact owns a 1998 audi a4. The ABS light came on and the brake light flashed intermittently while driving. The brake light has been on for the past two days.
Abs light and brake light started up on the dash, checked the owners book and it told you to cantact the audi dealer. Conatacted the dealer and was told that it costs a lot on money, quote for the part was $2711.00, not installed. Went to the web and found out that this is a big issue, and that there is no recall. Poor design and a very expensive part, who is making money out of this safety issue. Miles on the car 82k
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 and brake warning lights are illuminated on the dash. Took it to a dealer and was told there was no communication with the ABS controller. Dealer wanted $2600 for parts plus $450 (3 hrs) to replace. Vehicle only has 51000 miles!
Abs light comes on intermittently and ABS system is not functional. Abs system also used in electronic differential control. 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.
Abs light and brake light came on while driving. Pulled over and checked owner's manual which indicated loss of ABS, but full conventional brake power. Blinking lights went off by themselves after few minutes. Since the warning, I am experiencing slight resistance from brake pedal occasionally. Judging by postings on audi world.com, this has happened to several people. Waiting to get appointment for diagnostics and part replacement if necessary.
Abs light and blinking brake light came on intermittently after 55800 miles. Diagnosed as (possibly) a bad ABS control module. Also told it could be a bad instrument panel. Cost of $2200 quoted for ABS control module replacement with no guarantee that it would solve the problem. As a result ABS control module not replaced reducing safety of vehicle.
Abs light illuminated while driving 35 MPH. Vehicle was taken to the dealer, wh informed the consumer that the ABS brake module needed to be replaced.
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.
Car: 1998 a4 audi avant quattro, bought new. Abs controller module failed in 2004, audi should do a recall for safety reasons. No there were no deaths or injuries, is this a reason to have a recall when people die??
The ABS warning light illuminated after starting the vehicle ,and stayed on until vehicle was shut off. Dealership was notified, but did not resolve the problem.
(1) faulty design of ABS controller, 2) failure of said ABS controller, (3) ABS no longer functioning, causing a safety hazard.
1998 audi a4 2.8 quattro- my ABS sensor has failed. Abs light is on.
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.
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.
Abs unit failed on 1998 audi a4 2.8l quattro. Repair cost is > $2000 for a rarely used electronic module.
Control arms on driver and passenger side have gone bad in the last year. I dont think that is right for the parts to fail like that.. I bought the audi cause I thought it would be a safe and reliable car, when all it has been for me is a money trap.
Once vehicle warms ABS light comes on ,and the system is inoperable. Consumer had not serviced the vehicle.
