Hi I'm at a loss my 2014 BMW 328xi has been down since 12/10/22. It's too close to my house for wheel lifting dolly, no-one will tow to shop as I cannot get car in Neutral. Any guidance is greatly appreciated! I think it might be a fuse or electrical circuit issue. Details below:

Car threw itself into neutral w/drivetrain malfunction error message.

I Replaced battery w/non-AGM then w/AGM & was able to register the battery

Car cranks does not turn over
