2009 Audi Q7 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2009 Audi Q7


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.
