My Audi, along with thousands of others have had their abs control unit malfunction because of design. This malfunction causes the abs to not work on the affected vehicle. Volkswagen, the company that produces Audis and vws actually recalled this exact part on their vw vehicles, but for some reason refuses to correct the problem for their Audi customers. The cost to replace this control unit is $1,400 - $1,700, and as such I have been driving my vehicle without its abs functioning.

Braking performance seems to be dramatically reduced in wet, and especially wet and cold, conditions. This happens often, but does not happen regularly, and always after prolonged high-speed driving without brake application. The reduction in performance seems much more dramatic than would be expected from typical reduction in brake performance in these conditions.

Car experiences diminished braking abilities under wet/cold conditions. If roads are wet, even if above freezing conditions, braking suddenly to avoid other traffic results in near crashes or dangerous swerving to avoid accident. This is not due to poor road conditions but directly related to the Audi's braking abilities in wet conditions. Very dangerous and unpredictable. Have recently traded in vehicle and incurred large financial loss due to this and other serious problems.

After sitting for a couple of hours the brakes do not kick in right away if you immediately start the car and back up. You need to push the brake pedal hard and to the floor before the car will stop. Like there is an air bubble in the hydraulics. Many who have driven the car have nearly backed into other cars in parking lots. Fortunately there havent been pedestrians behind the car when this happened. 2 days after I bought the car I contacted prestige about the problem they said there was no sol the car still has this problem every day. You cant tell if the car is going to stop or whether it is going to roll into something. Once the car runs for a bit the problem is gone. On 3/15/01 I brought the car in & explained the brake problem. The svc agent said this was not normal & they would fix it. The problem was not fixed. On 8/2/01 I brought the car to prestige again. This time I insisted they fix the problem as there had been too many close calls. On 8/3/01 prestige said again it was a known problem & there was no fix. I insisted they keep the car longer to recreate the problem. . On 8/2/01 I called Audi client relations & reported the problem. Audi said they would fix the problem. She assigned case #10530656. On 8/7/01 the svc manager from prestige called & said they had recreated the problem & needed to get Audi involved to get the problem fixed. On Friday, 8/10/01, prestige said they were still working with Audi to get the problem fixed. On Tuesday 8/14/01, prestige left me the following voice mail "I just had a short discussion with my supervisor (dennis). He is in contact with Audi & we are trying to figure out what we might be able to dowhat were trying to do is see if Audi will make any adaptations to that or if there are any other options availablehopefully we should have it resolved it by Friday. " on 8/17/01 prestige called & said there is no fix. I need to let the car warm up for 20 seconds before I drive it in order for the brakes to work properly.
