Before thinking it was the alt we connected the battery and got a jump and it turned on. Then we disconnected the cables from the jump and the car turned off we we were sure it was the alt. After replacing the alternator the car gave the code and still does not turn on. Help please !

I have the same issue with mine. Idk if it was like that already or not. When I got my 05 545i the alternator was bad. I replaced the battery and alternator, registered the battery and I got the same message. I’ve checked all the fiber signals and they are all good. I’m going to have to get the laptop software and do what was suggested above. I hate having to learn all of this for a radio but it’s going to help me later and save thousands in the long run. Calling a dealer has never been my playbooks for over 30 years but seeing how this is my first bmw, I have no choice but to learn it.
