Vent the fuel system
The fuel system is vented via the electric fuel
supply pump.
In order to ensure that no error messages are
generated, no attempt should be made to start
the system up whilst venting.
This process is carried out as follows:
● Ignition "ON"
The electronic fuel supply pump switches on for
20 seconds in order to vent the fuel system and
build up the required fuel pressure.
Wait until the electric fuel supply pump is
disconnected from the control unit.
● Ignition "OFF"
Repeat the process at least 2 times until the fuel
system is vented
