  1. Move electrical wiring to Lambda probes clear.
  2. Remove Lambda probe after catalytic converter G130 and Lambda probe 2 after catalytic converter G131.
  3. Unscrew exhaust pipe/exhaust manifold securing nuts (arrows). [Note: The flexible joint in the front exhaust pipe must not be bent by more than 20° - risk of damage. To remove, ask for the assistance of a second mechanic.]

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.
