I bought my 01 A4 used in 2004. In 2008 the belt went. Audi repaired it. Now my blinkers, and the windshield washer do not work. In addition, there is a problem with orange fluid. There are more problems. Could it be that once an Audi goes beyond 10 years of age the car is done?

Please help, I don't know if I should sell the car or keep repairing it.

 

Any 10 year old car is going to have issues. Your turn signals and windshield washers are cheap easy fixes (probably). I'm not exactly sure what your "orange fluid" problem is though. I'm not aware of any fluids in your car that are/should be orange.
