“My vehicles instrument cluster does not work! It is clearly stated in the user manual that it should be replaced because it is for my convenience and safety to prevent considerable damage to my vehicle due to certain malfunctions. I would say that 90% of Audi owners I know, constantly complain about their instrument clusters either fading or going completely out. Something needs to be done about this. …”

“My driver information display hasn't worked since I bought the car in 2005. It's a 2001 Audi S4. The display in the instrument cluster displays important vehicle information vital to the drivers safety and vehicle maintenance.”

“I both own a 2001 Audi a4 and 2001 Audi S4.. On both the red lcd instrument cluster screen has failed to the point where nothing on that screen is legible. The screen is designed to show mileage, speed warning, run time and other functions. The pixels have ceased to function to the point beyond recognition. I share this problem with a very large group of Audi owners of the same and/or similar model. This group of people expands internationally and Audi clearly knows that this is a prone to failure part.”

“I had just purchased a 2001 Audi S4 for close to $40,000. With 1100 miles on it my car was stolen in broad daylight approx 3 pm. Upon further research, I learned that the factory passive alarm can be tricked into thinking it has been disarmed. A small hole near the door lock gains access to a rod that when lifted disarms the system as if a key were used, combine this action with the with removal of the ignition, and the vehicle can be started with a screw driver and driven away. …”

“I own a 2001 Audi S4. The center display on the gauge cluster is failing due to missing pixels. The center display normally displays critical safety information regarding failing engine and body components. It is always missing pixels, and is never clear enough to read properly. Recently, I developed an oil leak and the center display wasn't clear enough to see the low oil warning light. As a result I was stranded in sub-zero temperatures without transportation. I am currently repairing the engine far beyond what would have been necessary, had the center display been working correctly. …”
