Known issues on the 2006 A6 Quattro. Four recalls are on federal record for this model year. Three trace back to the passenger frontal air bag inflator module: in a crash requiring deployment, propellant degradation can cause the inflator to explode or rupture, sending sharp metal fragments at the driver or other occupants and risking serious injury or death. The fourth covers the automatic trunk lid, where a gas strut that loses pressure entirely can be misread by the closing software as a manual close command, causing the rear lid to close rapidly and risking 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 module inspection to a trunk lid strut and latch check or routine V6 or V8 service, it keeps you on the OEM procedure and the correct specification for your specific 2006 A6 Quattro.
