If there is air in the fuel system after a repair has been performed, this function can be used to bleed the system. By first activating the fuel pump for 3 minutes and then let the engine run with increased speed for at least 10 minutes.
Note:
This function must only be performed on sealed fuel systems.
Test prerequisites:
Ignition on, engine off.
Battery voltage higher than 12V.
No faults in the system.
No leakage in the fuel system.
Fuel level at least 10 litres.
Make sure the vehicle can´t move.
Gear in position P/N.
Procedure:
Choose the function:"Bleeding fuel system" and follow the instructions.
The fuel pump must be activated for at least three minutes to ensure that the feeding mechanism is sufficiently bleeded.
In the next step make sure the vehicle can´t move and for cars with automatic transmission the gearbox should be in position P.
Start the engine.
The idle speed will be increased and the rail pressure will be changed to pressure-controlled. The engine must run for at least 10 minutes in this condition in order to bleed the fuel system sufficiently.
Turn off the engine.
