The car has original battery still. If so where should I pick up battery? Dealers of aftermarket?
You don't need to test the battery. You just told us the voltage at which it sits and when its running. Its on its way out. The electrical system in your 7 series starts to prioritize its systems when the battery gets dangerously low to leaving you stranded. Like I said, my car did this when my battery was near dead. I thought my trans was having issues, and with a little research, I found out my battery needed to be replaced. I bought a new battery about 5 months ago. I haven't seen the issue arise since.

Go buy a new battery, have it registered to the vehicle and you will see no more codes.
