My vehicle has a problem the my anti-lock braking system light coming on and my brake light blinking. I've had this problem and though it was fixed the lights keep displaying. This I believe is a common problem amongst other owners of my vehicle as well.

Recently the ABS and brake alarm came on and when I went to have it repaired the service man said there was a four week back order on the ABS module. He said that this part is going bad in all the Audi A4's and some a 6's and he can't even get the part from a junked Audi.

Audi A4 2000 1.8T (1) ABS light flashing. Brought to dealer. Quoted $600 for repair kit, $1500 for new module. Both prices do not include labor. Searched internet and hundreds of other Audi A4 owners have experienced the same issue. (2) ABS is now intermittent on my car and warning light is on constantly. (3) can't correct right away B/C my Audi dealership is 6 months back ordered. I assume because so many owners are experiencing the same problem.

I have been having significant problems with braking during/after any type of rain. I have discussed this problem with many dealerships and they have denied ever hearing a problem exists. As common sense indicates, during any type of rain braking power will be decreased. However, the braking loss in this car is beyond acceptable limits. Please look into the problem accordingly.

While traveling in snowy conditions, and when depressing brake pedal vehicle went into extended stopping distance.

In rain there is a 2 second delay after the brakes are applied before they bite. This only happens in wet conditions.

- Cumming, GA, USA

During highway driving in the rain, water develops on the brake pads/rotors, causing the delay in braking. Water buildup seems to occur after about 2 minutes of driving in moderate or heavy rain. Braking delay is about 1.5 seconds. When brakes grab, they sometimes grap unevenly, pulling the car to one side or the other, until all 4 corners have cleared the excess water...then normal braking response resumes. I have worked as a professional driver, driving different vehicles over long distances...this is not normal!!! I know from on-line forums that Audi has not diagnosed the problem, and as such, does not have a fix out yet. I tried replacing brake pads, this did not help.

Brakes take 2-3 seconds to respond on first use when driving in very wet conditions. Has happened about 12 times in the last year. Dealer service department offered no fix.

- Oakland, CA, USA

Under wet conditions, braking is delayed. Especially noticeable when traveling at highway speeds, braking suddenly, and for a moment, brakes seem to not work.

- Sterling, VA, USA

Braking is poor in wet conditions. Takes 1 to 2 seconds before brakes respond.

- Uxbridge, MA, USA

I was driving at night on the road entering a highway at about 35 mph when I spotted something on the road. Being that my vehicle is AWD and equipped with ABS I broke and swerved. I felt no response form the brakes and by that time (2-4 seconds) my car had lost control and started to spin. The car spun and went to an exit lane and hit another car forcing it off the road before coming to a complete stop. The car is now undriveable.

2001 Audi A4 began to smoke. Drove 5 minutes to a friend's house and parked in driveway, consumer went inside of house, and car was sitting for 20 minutes. Then, someone knocked, and told consumer that car was sitting in the middle of traffic. Car disengaged on its own, and almost ran over two children. Took to dealer, and they said back brake pads, and rotors were burned to a crisp. No conclusion to why this happened or why car rolled into traffic on its own. Also, the brake pedal went to the floor when the consumer applied the brakes. The consumer's investigation showed that there were numerous reports about spongy brakes regarding this vehicle. The consumer feels unsafe driving this vehicke but the dealer and the manufacturer could not find solution to the problem.
