    Headlight Main Beam Not Working?

    I have a 2012 R56 Cooper SD with halogen headlights. My main beam is not working and I cannot find a Main Beam dedicated fuse, only two headlight fuses. The bulbs look OK, and it is unlikely any way that both bulbs would blow at once.

    Any ideas what to check? The blue main beam light does illuminate in the rev counter when I select main beam.

    Anyone know where I can obtain a wiring diagram?

    Thanks

    Headlight Main Beam not working

    Much obliged. Thanks for the info. Is it possible to identify wire colours from this system?

    It's been a good while since I used but yes from memory wire colours are marked up on the diagrams.
    You may need to install an old version of Java to view the site but a quick google will answer that question for you , this video may also help https://www.youtube.com/watch?v=t5v36iuwJuY

    Thanks for the info, it was useful but the problem is still not solved. In summary: If the headlights are "Off" and I pull the indicator stalk, the dip beam comes on and the blue light illuminates in the rev counter, so the indicator switch is working. If the headlights are "On", when I pull or push the indicator stalk the blue light illuminates but the Main Beam does not come on. I have checked both headlight fuses and changed both headlight bulbs but no difference. What could be causing this fault? If it is not the switch, fuse or bulbs, what could it be?

    The fuse box covers are pretty vague. The Haynes manual shows all of the wiring for the main beam going through a "Footwell Control Unit", whatever that is. It may be the equivalent of relays. Perhaps this is faulty? It must be something that would affect both headlights. It's odd that dip beam would flash when headlights are switched off but main beam does not flash when headlights are on?

    I'll take pictures of the fuse box covers and post them.

    Cheers

    Fuse Box Cover pictures. I have checked both 20 Amp fuses marked with a headlight symbol. Any others I should check? The Engine Bay fuse box lid does not show any Relays for headlamps. Any idea where they might be??? Thanks

    I think you may be onto something with the Footwell Control Module, I'm pretty useless at electrics but hopefully this link will prove useful? The Foot Well Module: functions, problems, solutions? - North American Motoring

    That's great. It looks like that may be the source of my problems. Not too keen on the price of fitting/coding a replacement though! I'll try disconnecting and re-connecting the connectors as a start.

    Thanks again
