2001 Audi A4 2. 8 abs brake system controller failure.
Abs electrical module that has failed and is apparently a huge problem, it affects the braking system.
While driving in suburban traffic, I noticed the brake pedal fully dress when I attempted to slow from about 30 mph. Upon subsequent stops, there was a metal on metal sound. Upon inspection, the right front outer pad had completely detached from backing plate. The car was inspected by Audi only 3k miles earlier and there was no indication of brake pad wear. Neither the dealer nor Audi would acknowledge or accept responsibility.
The brake squeals 90% of the time being applied, it happened since a few months ago. Brought to a local dealer a few times for the problem and reported with "cannot replicate the problem" and "noise is normal for some brakes", while the problem is actually getting worse and now the brake is making the squealing noise even after releasing the brake and last for one or two seconds - it happened especially after the foot brake was applied for more than 15 seconds and then been released (e. G. After waiting at a red light).
In searching for complaints filed for 2001 Audi A4's I noticed a number related to very poor braking in wet weather. I experienced the same problem with my 2001 A4. Audi does have a solution for this problem. The rotor backing plates must be replaced with a different design. When I brought it into the dealer for routine service and mentioned the problem no one in the dealership was familiar with the problem. A factory rep. Was visiting the dealership at the time and was familiar with the problem. He ordered new backing plates which, I am told, can only be ordered by a factory rep. It took 3 months for the parts to reach the dealership. I haven't had the problem since the new backing plates were installed.
