Just as an FYI, I have the exact same issue in my F31 (including same current software version). Took it to the dealer today, who also couldn't upgrade it with their own keys. He was even more confused when, on interrogating the key through their systems, some fields he was expecting to see populated (Integration Levels??) were all blank - unlike another car he showed me. He now needs to escalate to BMW direct - will update when I hear more.
