Known issues on the 2004 A8 Quattro. One recall is on federal record for this model year, covering the front air bags: during production, a driver's frontal air bag may not unfold properly in a crash and therefore may not inflate as designed, which can increase the risk of injury in a frontal impact. No complaints or technical service bulletins are logged for the year. The factory diagnostic and repair procedures behind that system are here.
Whether you're inspecting the air bag module or working through a scheduled service on the 4.2L V8, it keeps you on the OEM procedure and the correct specification for your specific 2004 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.
