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! *tr
Abs electrical module that has failed and is apparently a huge problem, it affects the braking system. *tr
