I am throwing the following fault codes

• 2DEC DME power management, battery
• 2DED DME power management, closed circuit current violation
• CDAB DME receiver FRM LDM LM transmitter
• A3B4 Receiver instrument panel, transmitter footwell module
• A3C1 same as above
• A559 instrument cluster: power supply has been switched off (closed-circuit current cutoff relay)
• A6D4 JBE central locking relay, unlocking
• A6D5 JBE central locking relay, locking

Is it worth replacing the battery to see if that is indeed the issue?
I feel like your battery is due but the jump starting somehow may have fried your FRM (footwell module) as well from the error messages and the lighting behavior.

But I did read some bad batteries sometimes causes weird electric issues so hopefully it's that but I think I'd definitely get a new battery considering it doesn't start on itself (if you went for a long drive at least 30 minutes).

I don't like to do the "parts cannon" and not diagnosing things though so if I were you I would get the battery tested to confirm but yeah.
Understood, just hoping to eliminate multiple repairs if only one is necessary
