i had strange problem this morning in my 335, basically started the car and message popped up saying left rear fog light failure. i tested and indeed it was not working, basically i just had to reseat it. i then checked to see if other lights were ok and found that switch to auto driving lights control does not work now, prob linked to ealier issue i reckon. well i checked a few fuses, just about as its so awkward placed in the glove and they seem fine. however on the fuse diagram, theres nothing relating to this auto light switch so iam not sure which fuse to check.the switch works in pos 1 & 2 but not 3. to put a spanner in the works i then left it on pos3 (auto lighting) switched on the front fogs and it works. also the small green led next to it lights up???
any ideas anyone??? do u reckon its a fuse gone and is it safe to remove a relay from the fusebox to check???
i'm still under bmw warrenty but i dont really wanna get charged as fuses r not covered.
