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.

Hi Schuppi,

Thank you for the assistance, I found the problem by unplugging all sensors at a time and was indeed the shift assistant that was faulty.

Much appreciated!
