Hi all,
@hakisalapaki
Did you check the DTC memory of ZGW and also the transmission control unit.
Or is there only no message on the checkcontrol panel in iDrive listed. This failure won‘t cause an CC-message or a warning light.
Do you have the 316i petrol engine as mentioned in your profile or is it a diesel engine? I thought that the petrol engine was not sufficent powerful to work with the 8HP automatic transmission.
The oil pressure within the transmission unit is too weak. So the change out of P is unavailable. By accelarating the motor rpm, the pressure raises und so the necessary pressure is available for shifting.
