2008 Audi Q7 Problems
An engine misfire may be noted after cold start resulting in illumination of the Check Engine Light. Our technicians tell us updated powertrain control module (PCM) software is available to correct this concern.
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.
