2005 Audi A4 Quattro Problems

Check Engine Light and/or Hesitation Due to Failed High Pressure Fuel Pump

2.0L turbo charged engines may develop a hesitation on acceleration and/or illumination of the Check Engine Light due to a failed high pressure fuel pump or a worn camshaft follower or camshaft. Our technicians tell us that whenever the high pressure fuel pump is replaced the camshaft and the follower should be checked for wear. The camshaft lobe pushes on the follower to operate the high pressure fuel pump. Frequent oil changes and use of synthetic oil may help with this wear issue.

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.
