- Press "“022 - End output”".
- Switch off ignition.
- Check the camshaft control valves . [Note: If the readout shows a value far below the specified value during the test drive, the camshaft control valve is working correctly and feeding the oil pressure to the mechanical camshaft adjuster, but the mechanism is not able to reach its end position (possibly because it is not moving freely).]

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.
