  1. Unfortunately BMW has been able to make the brake lights work with not only the Engine Control Module tied into the circuit but they managed to add a Light Control Module as well.

    I would request a free wiring diagram(see tab under Site Navigation) and trace the wiring before swapping out one of the modules.

  2. Did you initialise the switch? Once fitted, you have to pull the red part out fully, it`s on a ratchet, and is quite stiff, You need to press the pedal down in order to do this> with the red part pulled fully out, allow the pedal to return to it`s rest position, this will calibrate the switch. Hope that helps…
