Failure of abs brake control unit in an Audi 2001 A4 while driving on the freeway with snow. It occurred in salt lake city, utah. Abs brake light came on and the abs brakes weren't working driving on snow and needed to be replaced. $710. 00 was the cost of the repair for a faulty unit and a very common problem that Audi knows about it. Good thing that I was going really slow and I was exiting the slippery freeway at the time and I didn't slide. Thank you!.
1. One day suddenly my Audi 2001 A4 starts to show abs and brake light to be failing. 2. The failure when diagnosed seems to be a problem with Audi's abs control unit, and that needs to be repaired. 3. I have not repaired it yet, because dealers quoted a huge price of more than 1500$ to fix the abs control unit.
