Abs module failed approx may 2004 at 65000 miles. Abs not functioning and warning light remained lit on dashboard display. Replaced part with used ABS module from another audi a4. Old (failed) part is available.
1999 Audi A4 brakes complaints
Page 3 of 4: complaints 41 to 70 of 91, newest first, as owners wrote them.
Abs and brake lights on dash remain activated; mechanic says ABS computer module is not functioning. Very expensive repair - $1500. I have read of other reports of same defect in same model/year but no service bulletin I can find.
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.
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.
Failure of a bosch 5.3 ABS hydraulic control unit (part # 8e0 614 111a) in a 1999 audi 1.8 turbo quattro with 53,000 miles.
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. Http://tech.bentleypublishers.com/thread.jspa?threadid=3409&tstart=0 and http://forums.audiworld.com/a4/msgs/1743701.phtml . Apparently, audi knows about the problem but is not widespread enough to issue a recall.
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.*ak 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!!
The engine stalled without warning which caused the brakes and power steering to fail. *jb....
When the brake was applied, the vehicle experienced extended stopping distance.
Nar 1/15/2003. The vehicle often failed to stop during wet conditions. When the consumer applied the brakes, there was a delay before the brakes engaged, which has happened twice. It always seems to be a problem with the left rear brake.
The consumer states that the vehicles left rear brakes failed. Also states that the vehicle often failed to stop during wet conditions, the consumer will press the brakes and there is a delay before they would engage. This happened twice, and almost ran into an intersection, the left rear brakes squeak constantly upon application. The vehicle was taken to the dealer once to fix and it still squeaks. Scc ph
Wet braking 2/3 second delay of braking power when driving in rain at highway speed. Dt
Consumer states that while traveling at highway speed the vehicles brake pedal went to the floor, consumer had to use emergency brake to stop. Took to dealer, dealer stated ABS pump failed and brake fluid leaked out, causing loss of pedal pressure. Please provide any further information. Mr
My 1999 audi a4 experiences delayed braking during periods of moderate to heavy rain.
After traveling for several minutes on freeways in rain storms the first application of the brakes does not slow the car. There is a 1-2 second delay before there is any barking force regardless of pedal pressure. This isn't merely the typical lack of initial bite on wet brakes as with wet brakes the brake force will increase with increased pedal pressure. When this happens, instincts are to press the brake harder and when the water is finally shed the car will pull sharply in reaction to which ever of the brakes 'dries' first. Audi has designed and sells a plastic wing that fits around the inside of the wheel well at the underbody/wheel well interface to combat this but it only makes a marginal improvement. In addition, the 2002 audi a4 comes equiped with this same shielding in an apparent awknowledgement of the issue.
While emergency brake was engaged vehicle began to roll. Stopped at bottom of driveway, took to dealer and the dealer was unaware of problem.
There has always been a problem with the braking performance of this vehicle during wet conditions. This is only during highway or country driving where the brakes are not frequently applied. When brake pedal pressure is applied during these conditions, there is approximately a 1 to 2 second delay before the brakes start to retard speed. It feels or seems like there is a film of water between the discs and pads and this hesitation is occurring while squeezing or drying out this film of water.
Whenever roads are wet and brake rotors fail vehicle is very difficult to stop. Brakes fail to respond, causing extended stopping distance. Consumer has contacted dealer, dealer unable to determine cause of problem. *ak dealer replaced brakes, consumer states problem has somewhat improved.
It's the audi wet braking problem.
Under wet road conditions and hard rain, when applying brakes, consumer has to pump brakes a few times before there is any braking action. Dealer cannot find problem. *ak
Wet braking problem--I have no brakes (delayed) for the first 2-4 seconds during, or after a rain.
Brakes have a huge delay when driving in wet conditions. Unlike any car I have ever driven. When traveling at highway speeds it can be as much as a one second delay until the brakes kick in. I have contacted the dealer and they say that this problem can't be fixed. My only hope is that audi of america will do something about this.
When driving and upon depressing brake pedal when attempting to stop, experienced complete brake failure without prior warning which caused extended stopping distance. Also, directional signal and emergency lights malfunctioned.
Under wet conditions, brakes are dangerously slow to grab. There is a noticeable and very disconcerting delay of appx 1-2 seconds. The condition is worsened by driving without braking for distances >10 miles. Please, please, please contact audi concerning this problem as it is well documented and dangerous to me and others.
Poor wet weather braking - all times - about a 2 second delay before brakes grab
When driving between 50-55 MPH and upon depressing brake pedal to make a gradual stop slowly pumping the brakes, brake pedal traveled to the floorboard, causing extended stopping distance. Consumer noted that prior to the incident brake light was illuminating on the dashboard. Vehicle currently at the dealer awaiting service. Please provide any further details.
While traveling on wet roads and upon depressing brakes, they failed, resulting in extended stopping distance. Please provide further information.
Wires breaking caused air conditioner failure. Breaks pull to right when wet/moist. Door assembled wrong (caused wind noise) had to take in 4 times to repair.hood/ oil pump broke emptying oil on driveway. Front suspension squeaks and ABS comes on when backing up while breaking with wheels turned.
About a 1 second delay before the brakes grab when braking in wet weather.
In wet conditions, my brakes have delayed braking power. The wetter the conditions the more frequent and severe. After the delayed loss of braking power (approx. .5 to 1 second), the braking power appears to go back to normal. Similar to riding a bike with wet rims except that the car's braking power recovers faster. Very scary when you're cruising along on the highway in wet conditions with traffic and you come up on an unexpected bottleneck. I mentioned it to a dealer in santa clara, but he seemed clueless. He thought it was a function of the ABS, but I know what ABS feels like. I think it has to do with wet disc brakes.
