    When I unlock my M3 the passenger side headlight makes a noise like a motor running and it goes away when the headlight turns off.

    The light works, It auto levels when the ignition is turned on and is a non adaptive headlight.

    Any thoughts?

    I notice the headlight bulbs have been changed by previous owner and are now the ice white colour. Not sure if this could cause a problem.

    EDIT - BOTH HEADLIGHTS MAKE THIS BUZZING MOTOR NOISE!

    Is that low beam bulbs or angel eye bulbs? If it’s the angel eyes then it could be some dodgy cheap bulbs, try unplugging them and see if the noise stops.

    Mine also do this, I thought it was normal. Interestingly mine also have ice white angel eyes. I've noticed it doesn't do it if the headlight switch is in the off position.

    Finally getting round to investigating this, Turns out its a horrible tiny fan attached to a heatsink on the chinese led kit lol

    Nice eh?? So these will be going straight in the bin, I do like the white LED lights though, Any recomendations for a good quality kit?? I found these on ebay https://www.ebay.co.uk/itm/CANBUS-L...4e2b94d783d4e90ae2ad|ampid:PL_CLK|clp:2334524

    Might just go back to standard though.
