I was going to replace the battery myself but cleared the codes and charged the main car battery overnight with my Ctek charger and the error never came back. My car also fell into the 3G shutdown issue with BMW assist features so im not sure if that is a factor as now I lost all those features.
Wow so charging the main car battery overnight actually solved this issue for you...I might try that too.

A few times in the winter, after the car sat a few days undriven, I would get a notification for low battery discharge or something just because it sat for so long so maybe that contributed to this?
