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, and no technical service bulletins are logged. 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.
ON CERTAIN PASSENGER VEHICLES, DURING PRODUCTION OF THE DRIVER'S FRONTAL AIR BAG, THE AIR BAG MAY NOT UNFOLD PROPERLY IN THE EVENT OF A CRASH AND THEREFORE MAY NOT INFLATE AS DESIGNED.
LOSS OF FRONTAL AIR BAG DEPLOYMENT COULD OCCUR WHICH CAN INCREASE THE RISK OF INJURY IN A FRONTAL CRASH.
DEALERS WILL INSTALL A NEW DRIVER'S FRONTAL AIR BAG FREE OF CHARGE. THE RECALL BEGAN ON OCTOBER 6, 2006. OWNERS MAY CONTACT AUDI AT 1-800-822-2834.
