22 problems related to brake electric antilock have been reported for the 1999 Audi A4. The most recently reported issues are listed below.
My Audi, along with thousands of others have had their abs control unit malfunction because of design. This malfunction causes the abs to not work on the affected vehicle. Volkswagen, the company that produces Audis and vws actually recalled this exact part on their vw vehicles, but for some reason refuses to correct the problem for their Audi customers. The cost to replace this control unit is $1,400 - $1,700, and as such I have been driving my vehicle without its abs functioning. Below is a description of the recall for this exact part, but on the vw jetta: "2002 Volkswagen jetta GLS NHTSA recall id number: 02v031000 recall date: Jan 31, 2002 component: service brakes, hydraulic:antilock potential units affected: 55000 summary: on some passenger vehicles, short circuits can occur within the electronic control unit of the anti-lock braking system (abs). Consequence: this can result in a fire. Remedy: dealers will replace the abs control unit. Owner notification began March 8, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Volkswagen at 1-800-822-8987. Notes: Volkswagen of America,inc," please look into this issue and help vw to make the right choice for the safety of their customers and others on the road. Thank you for your time and attention to this important matter!.
Needed to replace the abs control module when my Audi only had 88000 miles.
The abs system of my 1999 Audi A4 intermittently fails. I intend to have it repaired as this is a safety issue. Repair shop, lusti motors in san diego, indicated that they've repaired other Audi's with the same issue recently. The cost of repairs is approximately $2,000.
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.
My 1999 Audi A4 experiences delayed braking during periods of moderate to heavy rain.
Wet braking problem--I have no brakes (delayed) for the first 2-4 seconds during, or after a rain.
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.
Car brakes unable to stop car during wet braking.
Brakes take 2-3 seconds to grab during wet conditions. This has happened many times. 2000 models have brake shields that 1999's do not have. Dealer says they cannot do anything until Audi tells them officially. Please investigate.
When it is raining there is a hesitation of a second or so when the brakes are applied.
In rainy conditions, the brakes exhibit a dangerous 2-3 second delay causing greatly impaired braking ability of the car. Almost hit a car in front in two instances despite more than adequate distance. Brakes work normally in dry weather however.
In wet weather brakes do not stop vehicle until depressed for approximately 3-5 seconds.
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.
The brakes on my 1999 A4 suffer extremely reduced performance (way beyond what is normal) in wet consitions. I realize that some reduced braking effectiveness is apparent in all cars in wet conditions, but twice now I have slammed on the brakes in very rainy conditions and nothing at all has happened for over a second!!!!!! other A4 owners have also reported this problem, and Audi responded byu enlarging the front brake shields for my2000 cars. There should be a recall to fix this defect; it is extremely dangerous.
Poor braking performance in the rain or snowy or slushy conditions, Audi ag has acknowledged a known problem with brake lining contamination, the following is off of their web page and in automotive news ***. . Read more...
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.
While traveling on wet roads and upon depressing brakes, they failed, resulting in extended stopping distance. Please provide further information.
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.
Momentary absence of braking during wet weather conditions-.
Delayed braking response in wet conditions. If the brakes are not used for some time in wet conditions, water will build up on the front rotors and cause a 1-2 second delay in initial braking response.
