2001 Audi A4 Quattro Problems

Fluid Leak From Transmission Output Shaft Seal

A fluid leak may develop from the propeller shaft seal on the rear of the transmission. Our technicians tell us that replacing the seal will commonly correct this concern.

Various Probelms Caused by Clogged Plenum Tray Drain

Clogged drains can allow rainwater to accumulate in the plenum tray (at the base of the windshield). The water may leak into the vehicle's interior, brake booster, or electrical components, which can lead to major problems. Our technicians recommend keeping the tray clear of leaves, pine needles, and other debris.

Check Engine Light Due to Vacuum Leaks, Oxygen Sensor, or Catalytic Converter Fault

Vacuum leaks, oxygen sensor failure, and catalytic converter efficiency faults can cause the Check Engine Light to illuminate.

I am having a serious problem with my Audi. Dealership doesn't even know what it is. When the oil temp. reaches 200 the oil light in car goes on and off every few minutes.
