shift lights can be turned on regardless via iDrive via m key settings, you just really need to step on the throttle as the shift lights are responsive to which gear you are in and the throttle pressure/speed of rpm build up....
even without idrive, you should be able to simply just active the shift lights with the obc stalk...
