Audi S8 Problems
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 and/or Engine Overheating Due to Failed Thermostat
The thermostat may erratically stick open or closed. The can result in illumination of the Check Engine Light and/or engine overheating.
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.
Inspect CV Boots and Joints at Each Service
Our technicians recommend having the constant velocity (CV) boots and CV joints inspected at each service. Servicing torn CV boots early can prevent the need to replace the CV half shaft or CV joint.
Check Engine Light Due to Faulty Torque Converter
A problem with the torque converter can cause the Check Engine Light to illuminate.
