Your codes are very similar to the post below - I don't have a way to convert them all to the traditional BMW p-codes. The plastic transfer case actuator gear can be bought separately and replaced for $20 or so. I have an earlier version without xDrive, so can't offer any personal experience, but people report a clicking noise from under the car when you turn it off if the transfer case actuator is shot (it will be that $20 gear). There are youtube videos showing how to replace it and showing what it sounds like. X3 have the same problem.

p.s. The radio can just be coincidential, or a wire is loose and the vibration of the DSC quiting is causing it to glitch. I would focus on the known issue and work on the radio second.
