🧭 Before you start

Fits: Audi A8 D2 (4D)

  • Also covered elsewhere: Electronic parts catalogue

Don't miss

  • Gearshift must be completed, vehicle is not rolling downhill and not in overrun after accelerating
  • The input signals from multi-function switch F125 can be checked on automatic gearbox control unit J217.
  • Allow vehicle to roll downhill or to roll in overrun after accelerating; do not press accelerator pedal
  • Check engine control unit identification and make sure that correct control unit capable of transmitting data via CAN bus is fitted: For correct version refer to Electronic parts catalogue. Or if control unit is defective
  • Check ABS control unit identification and make sure that correct control unit capable of transmitting data via CAN bus is fitted. For correct version, refer to Electronic parts catalogue. Or if control unit is defective

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.

Seen a figure that does not match your manual? Write to us — we correct it and note when. support@torqfix.com
