2006 Audi A8 L

On certain vehicles, in cases where a weak battery exists, it is possible that a low voltage condition could cause the airbag control unit to improperly set a fault code.  If this occurs, the passenger-side frontal airbag will become deactivated and would not deploy during a frontal crash.  As a result, a passenger-seat occupant could receive more severe injuries.  Correction: Dealers will update the airbag control module software.

On certain vehicles, an improperly routed ground in the front passenger-side airbag and seat heater harness may cause signal interference.  This can result in the deactivation of the passenger-side frontal airbag under circumstances when it should remain activated.  If this condition occurs, the passenger-side frontal airbag would not deploy in the case of a frontal crash, possibly exposing the occupant to risk of injury.  Correction: Dealers will modify the wiring harness.
