Audi Problem

My check Engine light came on a week ago. Turned out the temperature sensor needs replacing, but since it is in or near the engine, it takes 6 hours of billable time to get it replace. Funny thing is that another gentleman in the waiting lounge has exactly the same problem. Mine is a 96 A4, his 97. One has 60K, the other has 80+ K on it. Not sure if statistically there is a significant, but sure sounds like the car has known issue They gave me a rental for the day. It is a Ford ZX2. Pretty fun little car. However today we have snow, and it is amazing how much harder to drive with this zippy FWD car compare to the Quattro. Now lets wait for the A4 Cabrio with Quattro coming out next year.
