There's a whole bunch of power codes in there that suggest that the battery died or got very low. When I have a sea of codes, I generally clear them and see what comes back after a drive. There's a good chance you'll have a lot less of them to deal with. BMWs throw all kind of errors when the voltage gets too low.

Edit: Also, charge the battery and confirm that the alternator is outputting ~13.5v or higher.

I genuinely would not do any other diagnostic work until you've done that.
