Instrument cluster on my 2002 audi s4 has failed. Without this display, the potential for a hazardous situation increases due to not being able to read the errors which would normally be displayed. I am aware of this being a very common faulty part and would recommend looking into a recall. *tr

I bought my car with 36,xxx miles on it. The center lcd screen does not work. The car is practically brand new and the center cluster information center is busted. Its barely readable, but display important user diagnostic/info about the car (service lights, etc). This is unacceptable and i would like to prompt a recall. It's a 2002 audi s4, 2.7t the previous owner complained to me when i bought the car that it never worked for him either. (he owned car for nearly 2 years+). *tr

Tl*the contact own a 2002 audi s4. The center instrument panel display intermittently failed to illuminate. When the failure occurred half of the display was well lit while the other half was not. Occasionally there was also an odor similar to electrical smoke. The dealer was not notified of the failure since the lights on the instrument panel do not remain illuminated. The driver stated that a cable may be disconnected within the instrument panel which may be a common problem. The failure has occurred intermittently for one year. The failure mileage was 85,000.

1. Purchased a 2002 audi s4 2.7t. 2. The auto check system in the instrument cluster does not work especially when warm. The lcd ribbon cable looses contact and doesn't display the information it should. Critical safety information is no longer displayed. 3. Was quoted obscene amounts by audi dealers to replace entire instrument cluster. $250 for a used cluster that would need the odometer adjusted for an additional fee. *tr

Tl*the contact owns a 2002 audi s4. While driving approximately 45 mph on normal road conditions, the instrument panel displayed missing and faded pixels, as well as incomplete information about the vehicle. The failure occurred without warning. The vehicle has not been repaired. The failure mileage was 60,000 and current mileage was 120,000.

The brakes boost/vacuum assist line check valve cracks apart into two pieces. This causes the total loss of the power assisted brake system in the car and subsequently makes it very hard to stop the vehicle. There is no warning about the pending loss of brakes. One second you have brakes the next it feels like you are trying to push a brick thru the floor of the vehicle trying to get it to stop. *nm

Dashboard instrument cluster led display is burning out. *jb

Cam cover oil leaks discovered after 50,000 mile service at approx 48,500 miles 11/7/05. Audi tsb 05-03, nov. 2, 2005 covering 2000-2006 models a4, cabriolet, tt, a6, s4, allroad, a8, s8, and rs6 with engines 1.8t, 2.8 v6, 2.7 v6t, and 4.2 v8 states that if a customer complains and the area is wet with fluid residue or droplets that are not coming off, to clean the oil stained area and tell the customer that it could be the result of spillage when topping off or normal gasket "sweating" and is not indication of a malfunction. If found and no customer complaint, no action is to be taken. If found and only if a customer complains, then replace gaskets and leak test the engine. This is an unacceptable policy of hiding by lack of disclosure, the leak and unfairly shifting the cost of a manufacturing or design defect to the customer. Audi needs to be held accountable and forced to cover these leaks for an extended period of time and notify owners to bring their cars in for inspection and repair. *jb

Ongoing complaint: brakes vibrate when stopping. Dealer reported front rotors warped and pads have chunks missing. Dealer replaced with part nos. 8d0-615-301-m front brake discs and 4b3-698-151 front brake pads/linings. The car was returned to me with the vibration still present.

I purchased my audo s4 avant new on nov. 10, 2001. It has 26,000 miles on it. There have been at least 6 repairs performed to correct brake pulsation or vibration. Pads and/or front and/or rear rotors have been replaced. The car leaves the dealership service facility operating normally, but within a few thousand miles the condition returns.
