Was bedeutet der Fehlercode?

Reverse cannot be engaged because the control module has blocked it, due to a fault that could damage the transmission if driving or shifting continued. The code is event-driven and usually shows a temporary disturbance, especially in new cars or transmissions whose parts have not yet bedded in.

Mögliche Ursachen

Damaged valve
Electrical fault not yet detected
Hydraulic fault not yet detected
Damaged shift mechanism

Was Sie tun können

1Read and clear the code, then road test in reverse to see whether it returns
2If it does not return, it was most likely a temporary disturbance and no action is needed
3If it returns often, consider how many miles the car has covered and how often the fault shows, and tell the workshop
4If the fault remains, have a workshop check the valve, the hydraulics and the shift mechanism

Symptome, die Sie bemerken können2

Yellow warning symbol and text message in the display
No forward or reverse movement in gear

Was der Fehler beeinflussen kann1

The control module blocks gears to protect the transmission
