- For that, press the keys on hose connectors.
- Risk of splashes when opening the key lock; keep a container in front of the free end of the Pressure gaugeVAG 1318. — Reduce excess pressure by carefully opening the valve.
📋 Procedure
- ⚠ Fuel supply pipes are under pressure! Before loosening hose connections, put a cleaning cloth on connection points. Then depressurize by carefully pulling the hose. — Remove supply hose (1) from fuel filter inlet and connect it to the Adapting setVAG 1318/17 and the Pressure gaugeVAG 1318.
- Install the AdapterVAG 1318/1 on the AdapterVAG 1318/11 of the Pressure gaugeVAG 1318 and put the hose end in a 3.0-liters (minimum) graduated container.
- Remove supply hose (1) from fuel filter inlet and connect it to the Adapting setVAG 1318/17 and the Pressure gaugeVAG 1318.
- Install the AdapterVAG 1318/16 on the AdapterVAG 1318/11 of the Pressure gaugeVAG 1318 and put the hose end in a 3.0-liters (minimum) graduated container. [Note: For that, press the keys on hose connectors.]
- Close the valve on the Pressure gaugeVAG 1318 (transverse valve to the direction of the flow - position (B)) .
- Activate the Remote controlVAG 1348/3A in quick intervals, until reaching a pressure of approx.:
- ⚠ Risk of splashes when opening the key lock; keep a container in front of the free end of the Pressure gaugeVAG 1318. — Reduce excess pressure by carefully opening the valve.
- Check the pressure drop on the Pressure gaugeVAG 1318. After 10 minutes, the pressure should not have dropped below 2.5 bar.
- Check line connections for leaks.

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.
