Correct! The rear fog light in the USDM/EU/Asia cars are also used if you have the brake force display coded which flashes the rear fog light if you slam on the brakes

Within Carly or Bimmercode I believe there are 2 values you need to enable to in the rear light module to be able to toggle the switch
