Known issues on the 2004 S6. One recall is on federal record for this model year, covering the electrical system: if a driver's knee presses against the knee bolster under the dashboard, it can contact the headlight switch wiring harness and cause an electrical short, with the potential for a fire to originate in the left dashboard area. No complaints or technical service bulletins are logged for the year. The factory diagnostic and repair procedures behind that system are here.
From a dashboard wiring inspection to routine service intervals, it keeps you on the OEM procedure and the correct specification for your specific 2004 S6.
ON CERTAIN PASSENGER VEHICLES, IF A DRIVER'S KNEES PUSH AGAINST THE KNEE BOLSTER (CRASH ELEMENT) LOCATED UNDER THE DASHBOARD, IT CAN CONTACT THE HEADLIGHT SWITCH WIRING HARNESS, AND AN ELECTRICAL SHORT COULD OCCUR.
A FIRE COULD ORIGINATE IN THE LEFT DASHBOARD AREA.
DEALERS WILL INSTALL A PROTECTIVE COVERING ON THE KNEE BOLSTER (CRASH ELEMENT). IN ADDITION, THE WIRING HARNESS AS WELL AS THE FELT PROTECTOR ON THE LEFT SIDE OF THE DASHBOARD CARRIER WILL BE CHECKED
