Excessive Battery Discharge & Strange Electrical Problems

Cross-posting from XOutpost incase some of us don't go to both forums.

2012 E70 35D
So I have been getting the "excessive battery discharge" message. I had also received some message that said the car was shutting down some systems s a result, though I did not take pic of that message, or remember exactly what it said. I did notice a text that said the headlights moving with my steering was being shut down, and my "one touch start," and some of my comfort door lock features stopped working.

As part of troubleshooting this I checked the battery, though I know that's not the cause of this message. The battery was the original from 2012, so I replied it. Then I reset my coding to turn back on all of the comfort stuff. Everything but the "one touch start" started working again. Then a few days later I got the same "excessive battery discharge" message. Before al of this started I did notice the my passenger side front door handle would not lock/unlock the doors like the others do. That has been going on for a long time before the "excessive battery discharge" messages started though.

Today I tulles my error codes and talking to my Indy Mechanic. He is not sure what to make of the codes, so I thought I would, ask here. Anyone have any thoughts or suggestions?
