The anti lock brake control modulator unit failed, and now I have brakes that do not work. At the slightest pedal pressure, all 4 wheels will have a strong pulsating, giving you about 1/3 of the braking pressure that is needed. Volkswagens used a nearly identical part, and their ABS controller is under recall, I do not understand why NHTSA, cannot force Audi of America to do the same. Thank you

The ABS control unit on my Audi A4 failed after 95,000 miles. I have no anti-lock braking 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 and found that it indeed does not prevent my brakes from locking up. Nearly three years later, the part has not been fixed due to the high cost to repair it.

Out of nowhere, ABS light on, brake light flashing. Took to shop, they stated this is a common problem for the ABS module to lock out communications; 1400 + for the repair. This is an expensive car; I find it outrageous the electronic module is outside, subject to weather conditions and salt. Please see my complaint on coil springs as well. Researched the problem on the internet and it seems this is usual and customary for this model, I feel NHTSA needs to step up here and call Audi on the table.

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.

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.

Terrible wet braking performance, the first 1 or 2 pedal applications in the rain cause no slowing down. The pedal needs to be pumped to dry the rotor. I went through several brake pad compounds with no improvement. Of all the Audi that I owned, the A4 brakes are the worst. Hell, these brakes are the worst of all the cars that I owned!

1998 Audi A4 1.8 liter quattro. Experiencing reduced braking capability when brakes are wet. This is the exact complaint being investigated in NHTSA action number PE00016. The brakes work fine when dry, but effectiveness is greatly reduced when wet, and stopping distance increases significantly, causing a safety concern.

I have had many close calls in rainy weather when trying to stop in my 1998 Audi A4 1.8T quattro. In dry weather braking is fine. This is a serious problem that needs to be addressed. I am more than certain I would have hit someone if I would not keep a greater distance knowing the horrible braking performance in wet weather.

Consumer stated that when braking and without warning they will have bad brake performance during rainy weather causing the vehicle to have extend stopping distance. Dealer notified.
