This is like a check engine light for your transmission and it's finnicky. For some reason, and there can be many, the computer has detected some sort of failure and has decided that the transmission is at risk from whatever it has seen. You need a BMW approved transmission shop to diagnose this to find out what caused this. It might be as simple as low fluid or a sensor. But being a BMW, it probably won't be cheap.
