Registering the battery as new and setting the Ah rate are two different things.
I was mostly referring to registering the battery as new.
What OBD2 device are you using? Can it read the battery charge histogram?

I actually have that same device. It only shows new battery registered because it uses Ah learn mode. While the DME/DDE is still learning, it would have your alternator output all over the place.

There seems to be a lot more going on with your vehicle than just the over-voltage condition.
BMW charging system is complex. It is maintained by the DME. So, there are many components to check. I am simply walking you through checking each component.
