Instrument cluster stopped working. Vehicle mileage, and speedometer do not work at all. Mileage when occurred 48,800. Every speed sensor was replaced with no change. I have no way of knowing how fast I am going, or how many miles are on my car without tracking them myself. This is a common problem with multiple vw's and Audi's with no apparent solution. I have spent hundreds of dollars trying to fix this problem and still am without a speedometer and odometer.
