2008 Audi S8 Problems

Rainwater May Accumulate in Plenum Tray Due to Clogged Drains

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.

Oil 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.

Overheating Due to Failing Thermostat

The thermostat may erratically stick open or closed. The can result in illumination of the Check Engine Light and/or engine overheating.
