Just purchased a tow ball-mounted bike rack, which has a light bar, for my car and I've noticed that when connected the blind spot monitoring system stops working. There is no fault message on the binnacle or fault code logged. The orange led remains on in the door mirrors.
Is this normal behaviour?

Yes, if the towing electrics have been coded to the vehicle then BSM is disabled and also rear fog lights and PDC (I'm speaking from a L405 knowledge, but imagine it would be the same).
