The Check Engine Light may illuminate with a knock sensor code stored. Our technicians tell us a revised knock sensor and bracket should be installed, along with heat shielding material to protect the new sensor, to correct this condition.
Uneven ride height and/or tilting of the vehicle may be caused by one or more stuck closed residual pressure holding valves. A service bulletin from Audi describes how to properly test these valves. Any valve failing this functional test should be replaced.
The Check Engine Light may illuminate due to various camshaft and crankshaft position sensor and/or correlation faults. Our technicians tell us that revised powertrain control module (PCM) is available to correct this concern.
