- If the high pressure fuel pump was removed or replaced, then bleed the fuel system before starting the engine for the first time. Filling the fuel for the first time. Refer to FUEL TANK, FILLING WITH FUEL AFTER INSTALLING HIGH PRESSURE PUMP .
Special tools and workshop equipment required
- Vehicle Diagnostic Tester
To fill the fuel system with fuel, proceed as follows:
- Check the fuel gauge in the instrument cluster. The gas needle must not be in the reserve area.
-- Connect a Vehicle Diagnostic Tester.
-- Turn the ignition on.
-- Select "engine electronics" in OBD.

-- Let the engine run for a few minutes at an average RPM and then shut it off.
-- Check fuel system for leaks.
-- Erase the Diagnostic Trouble Code (DTC) memory.
-- Perform a road test where the accelerator pedal is pressed all the way down at least one time. Then check the high pressure area again for leaks.
If there is still air in the fuel system, the engine may switch to emergency mode during the road test. Turn off the engine and erase the DTC memory. Then continue the road test.
