Radio shuts off, 4x4 / dsc inactive, abs, (!) warning light, transmission fail safe,

HELLO. LET ME EXPLAIN:

I have a 2006 bmw x5. recently I have been having a lot of problems. it all started with my radio turning off then on and my 4x4 inactive warning light would come on. then this would happen: radio cuts in and out, 4 x4 / dsc inactive, abs, (!), transmission fail safe program display pops up, last things was my engine light. once I turn car off and back on sometimes resets. when my abs and (!) warning lights come on I can feel the brakes being applied on my tires. I took it in to mechanic with all lights on, he tells me that its either my transfer case motor or the whole transfer case needs to be replaced. he takes it apart and everything checks out. he tells me all my sensors are working and cant figure out whats wrong. he then tells me he did a master reset so the car is like brand new, I get in my car and my radio doesn't work now and immediately after I leave his lot all lights come back on. I take it back and he tries to fix radio he tells me all fuses are good but cant figure out why my radio is completely dead no sound no audio. he plugs into to scanner, he gets no codes but can turn my radio on from scanner but I will have no display or cant control the radio or station. he also tells me the scanner is picking up codes for low battery and bad alternator, so we agree to get new alternator and new battery. after he fixes the alternator and puts in new battery, the 4 x4 light comes back on the dash and wont go away now and I still don't have a radio!!!!!!

please help me. I need to know if its not the alternator/sensors/battery/transfer case or motors, then what the hell could be wrong with this car?
also what could be wrong with my radio?

I had the same issue. It was the alternator charging at 17.4V. Did the put a new or a rebuilt alternator? Check my posting high alternator voltage. 4x4 light will disappear after you drive few kilometres or after few starts. Good luck.
