Power Steering Gear Components

WARNING: Airbags and related equipment (e.g. steering column) must only be disassembled, assembled and repaired by trained Audi Service Department personnel. Disconnecting the battery alone will NOT prevent the accidental deployment of the airbag(s). Before working on any airbag or steering column component, always disconnect the airbag power supply harness connector, and refer to all airbag system Warnings and Cautions.

CAUTION: Before working on any part of the electrical system: Determine the correct coding for the anti-theft radio. Disconnect the battery Ground (GND) strap.

CAUTION: Do not attempt to weld or straighten steering system components
