Although I am a software engineer, I admit to not knowing jack-sh*t about the many CUs in cars and related tech. I guess it is time to change all of that.
Those look like BMW specific codes to me(I could be wrong). I had an OB2 handheld that read generic codes so the errors should show up regardless. The problem was, the CEL didn't go away after I restarted the car, so I have no idea if the generic OBD2 would work.

Might be worth popping over to Advance though, could save yourself $300 by not buying the BT tool, if it works. Good luck!
