Reading and clearing it
Fault code 0011 is a BMW code, stored in the car's digital sound processor, 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 digital sound processor is on: 7 Series (E38), 5 Series (E39), Z8 (E52), X5 (E53), X3 (E83), Z4 (E85), Z4 (E86)
