2006 Audi A6 Service and Repair Manual

This 2006 Audi A6 factory service and repair manual is built around the 3.2L V6 (engine code BKH) as delivered that year, so the torque values and diagnostic steps you get are the ones written for this exact drivetrain rather than an approximation from another A6 model year.

Known issues on the 2006 A6. Four recalls are on federal record for this model year. Three separate campaigns cover the passenger frontal air bag inflator module: propellant degradation in the inflator can cause it to explode or rupture, sending metal fragments toward the vehicle's occupants and resulting in serious injury or death. A fourth recall covers the automatic trunk lid, where a gas strut that loses pressure can be misread by the closing software as a manual close command, causing the lid to slam shut rapidly and creating a risk of personal injury. Owners have filed 67 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From an air bag inflator inspection to diagnosing the automatic trunk lid's strut and clutch behavior, it keeps you on the OEM procedure and the correct specification for your specific 2006 A6.
