Reading and clearing it

Fault code 011B05 is a BMW code, stored in the car's hybrid master control module, not a generic OBD2 code (P0xxx): a generic OBD2 reader only reaches the engine's emissions faults, so it won't show it. AutoLingo for BMW reads it with BMW's own diagnostic protocols, in plain English, with the details the module stored about it, and clears it after a repair. If a fault comes right back after it's cleared, the problem is still there.

The hybrid master control module is on: X6 (E72)
