Known issues on the 2005 A8 Quattro. One recall is on federal record for this model year, covering the frontal air bags: during production, the driver's frontal air bag may not unfold properly in a crash and therefore may not inflate as designed, increasing the risk of injury in a frontal collision. Owners have filed 6 complaints for the year. The factory diagnostic and repair procedures behind that system are here.
From verifying air bag module integrity to routine service on the V8 or W12, it keeps you on the OEM procedure and the correct specification for your specific 2005 A8 Quattro.
