Just a heads-up, I just checked in the code for my car and it says that the 'nebenschlusslicht' (fog light circuit) is turned off. You probably need to activate this indeed before it would work
(btw, in relation to the brakeforced lights, they're supposed to be there on the US F30 (they're advertised, after all.. although I have no clue how they start working), and these are enabled in the code (if they were not working, they most likely wouldn't be enabled)
).
