📋 Procedure

  1. ⚠ Gas system tests must only be performed by specially trained personnel trained at regular intervals.Autogas is highly inflammable and, in combination with air, creates a combustible mixture.There must be no open flame or source of ignition near the autogas system.Inhaling autogas can lead to light-headedness and lung damage. High concentrations may lead to suffocation due to lack of oxygen.Autogas is not odourless because substances having a strong odour are added. — Connect adapter for gas leak detectorVAS 6227/1 to lines (1).
  2. Fit magnetic release tool T10349 to solenoid valve (1).
  3. Using gas leak detectorVAS 6227, check all components, connections and lines for leaks. [Note: When leak detection spray is being used, it must be ensured that no bubbles come out of the sprayed area within 3 minutes.]
  4. Locate and rectify leaks.
  5. Then, repeat leakage test using gas leak detectorVAS 6227.

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.
