from the battery compartment. A plastic panel was removed for inspection. Located directly under the battery was a plastic module identified as trw *334 gnoacdobnc28u* and stamped made in malaysia??. The dealer stated that the module controls the electric parking brake for the car. Inspecting the unit, multiple wire leads that feed the e-brake control unit had burned through, as did a portion of the e-brake control unit. The body area of the car near the unit was covered in soot from the electrical fire. Years prior, the driver had issues with the e-brake, the e-brakes failing to release prompting the vehicle to be towed to the dealer. At that time the service representative walked the driver into the service area to show the driver corrosion on the electric contact leads from the control unit. The representative suggested that perhaps battery acid/gases may have run down the battery into the control unit causing the corrosion. The unit may have been replaced at that time along with the battery. Photos are available of the control unit upon request. *Tr

SuspensionAcceleration & cruise controlEquipment & accessories

I own a 2004 audi a8 quatro, this morning the car accelerated on it's own. The driver seat, steering wheel, and the car suspension adjusted automatically while I was driving it and it went from 40mph to 150+ without me having my foot on the accelerator. For a minute I thought I was going to die. I slowly starting pressing on the brake pedal hoping the car would not flip. It took about 2 to 3 minutes for me to slow down the car. I put the emergency brake and turned it off. I turned it back on and the engine was still accelerated, it sounded it like the accelerator was stuck even though the car was on park. *Tr

Visibility & wipers

The windshield wipers will stop intermittently. They have stopped during heavy rain on an expressway several times resulting in a loss of vision. The dealers could not get the problem to repeat so they said that they couldn't do anything. I called the audi advocate phone line and was told that audi would not address the issue. Then I wrote audi and ask for a refund and the audi advocate returned the call and maintained the same response. *Tr

2004 Audi a8l, purchased in 07/2004. Front wipers "hesitated" in the rain a couple of times. Local dealer said could not reproduce. A few months later, wipers completely stopped, while driving at highway speeds, leaving me without visibility for several minutes. Pulled over and removed/replaced fused. Wipers started up again. Local dealer said couldn't reproduce. Wipers failed two more times, and hesitated numerous other times, when I finally decided to not drive the car. Throughout all, dealer claims he's...

unable to reproduce the problem, audi america disclaims all liability for accidents from wiper-failure. Car was garaged as unsafe to drive for the remaining 17 months of the lease. Just this week I found out that audi germany knows about this problem, and has redesigned the wiper-motor before 02/2004. Numerous reports of this failure have surfaced on the internet, and exchanging the wiper-motor alleviated the problem. Audi should recall all affected vehicles and replace the wiper before someone gets hurt or killed. Furthermore, I request audi refund my last 17 lease-payments as well as insurance and registration cost for the vehicle while it was garaged. *Tr
