Don't miss
- After installation, the high-pressure pump MUST first be filled with fuel before the engine is started (the pump must NOT be allowed to run while still empty; risk of irreparable damage). — Connect .
- Repeat this procedure THREE TIMES to ensure that high-pressure pump is sufficiently filled with fuel.
📋 Procedure
- ⚠ After installation, the high-pressure pump MUST first be filled with fuel before the engine is started (the pump must NOT be allowed to run while still empty; risk of irreparable damage). — Connect .

- Repeat this procedure THREE TIMES to ensure that high-pressure pump is sufficiently filled with fuel.
- Start engine after filling fuel system.
- Run engine at moderate speed (greater than 2000 rpm) for approx. 2 minutes and then switch off.
- Check fuel system for leaks.
- Erase entry in event memory using diagnostic tester.
- After completing the repair, road-test the vehicle. Accelerate with full throttle at least once. Then inspect high-pressure section of fuel system again for leaks.
- Interrogate event memory.

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.
