Not sure if everyone here is aware of the Alpina TCU flash, but maybe it is possible to flash the car to RWD in a similar fashion?
Instead of flashing the the EGS module with an Alpina number for Alpina's transmission algorithm, maybe it is possible to flash whatever module (DME?) that controls the xDrive with a RWD car's number?
