Hello, I recommend contacting an electrician, the problem is clearly with the electronics, you need high-quality diagnostics

Looks like the main issue is with your boost system, likely a leak, sensor, or turbo fault causing the drivetrain error. I think it's a good idea to fix the faults in the exhaust temperature and oil level sensors, but I'm not sure they're the main ones.

That 2a0d00 bmw fault code points to a LIN communication fault with the alternator. which could also be serious if the car isn’t charging right. Check the alternator wiring and connector first; if that’s ok, the alternator or its regulator could need replacing. Start with those and see if the warning goes away.

Did you notice any other symptoms, like dim lights or battery warnings, before the codes popped up?
