Does anyone know how to perform a master reset? I was driving at speed, around 65mph, my car went into limp mode. Now the car will not shift into gear. Just stays in neutral. Any suggestions would be greatly appreciated.

I did get a transmission overheating message, the visit a service center message. The fluid levels are ok, no visible leaks.

The gearbox is getting too hot and locking you into neutral on purpose.

Check your water pump, failed pump can cause this. Check your coolant level as well and for any leaks. Concentrate on this

Dont waste time pissing around with resets. It wont fix it.

Thanks - I'll check this also - The car has been sitting for a few months now - Still in Neutral

I was able to get a few codes from the car today -

P0851 - Park/Neutral position not plausible
U0167 - Immobiliser :: Invalid or missing data/message from SBC
P0701: Transmission intervention not plausible
