In case anyone is interested, I ended up taking it to an independent shop. I bought the battery from BMW (it was around $200) and the shop charged me around $30 to install it. They told me that they don't need to register it because they use a battery tender (never loses a charge). I got no error codes and has been running fine for over 2 weeks now.
