Brake Electric Antilock problems of the 2000 Audi A4

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.

Faulty abs control module. . . Cause loss of abs braking in 2000 Audi A4 with on 60k miles. This has cause many close calls as it is $1500 to repair.

Car has only 62,000 miles, but anti-lock brake system controller failed. Manufacturer refused to replace; replaced at my expense.

My car has less than 50,000 miles and I having abs brake problems. The brakes pulse a low speeds for no apparent reason. There are no warning lights displayed from a failure in this system. This car has not been in any accidents and it was dealer maintained until the warranty ran out 1 year ago.

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

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.

In wet weather, 1 - 2 second delay from brake pedal application to brakes deploying. Dealer contends that brakes are operating within specification.

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

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

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.

Vehicle experiences degraded brake performance in wet conditions. Dealer is scheduled to inspect vehicle.

While driving in heavy rain, the rotors felt as though they had a sheen on them that caused the brakes not to function immediately. Almost as if the vehicle was sliding on ice. This occured 4 times in the coarse of a 150 mile trip from philadelphia to new york city.

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.

Wet-braking problem. During heavy rain, water droplets accumulate on disks and cause a 2 second delay in braking action!!!.

When brakes are wet after driving a long distance and are not used - they fade the first time you use the brake pedal.

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

Initial braking in wet conditions is poor. After approximately 30 seconds of non-use of brakes in heavy mist or spray, or any precipitation, there is little to no braking action for approximately 1 second after the pedal has been depressed. No brake pedal "pulsing" (associated with abs activation) is noticed. Cruise control was not active each time the problem was noticed. The problem is more noticeable at highway speed. Brakes are otherwise excellent.

Brakes do not perform well in wet weather.
