Hello
The DME detects a voltage deviation in the 5 V power supply of the component group 4.
The voltage supply to component group 4 is switched off if the permitted deviation is exceeded.
Disconnect all components listed below and clear the fault memory.
If, once all components are disconnected, the fault entry then is
a permanent fault: Check wiring harness for insulation damage.
not a permanent fault: Successively connect each component again until the fault is entered again.
Components in component group 4:
Gear selector sensor
Gearshift lever sensor (if installed)
Fault Impact
Gear display not plausible.
Engine can only be started with the clutch pedal depressed.
