Reading and clearing it
Fault code A92F is a BMW code, stored in the car's lane departure warning, 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 lane departure warning is on: 5 Series (E60), 5 Series (E61), 6 Series (E63), 6 Series (E64)
