This function is used to bleed the fuel system after completed repair. By first activating the fuel pump for 3 minutes and then let the engine run at increased idle for at least 10 minutes.
Note:
The following fault codes for regulation of the pre-supply pressure may be registrated when activating the fuel pump: 26D000 and 26D200. Ignore these and erase at the end of the function.
Condiţii de testare:
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:
Start the function and follow the instructions in the program.
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.
