    My headlight has stopped working, I bought a new bulb (as you would) but that didn't work either. When I took it to a garage they said it was the 3 pin Xenon igniter. So I bought one of these (£98 from BMW!) and it still didn't work. Before I go and buy a new headlight I was wondering if anyone had the same problem or has heard of this happening before?

    Any advice greatly appreciated

    Jack

    why buy a new bulb, xenon bulbs are expensive , if you have no test equipment then be very carefull , i take it you know what voltage you will be dealing with , and you can see the warning stickers ? , what i would do , remove both front head lights and swop the good one over to the side its not working , i know they wont fit but just connect the wireing up to the light , if the light comes on you know its in the lamp unit . if the lamp does not come one , you need to trace the fault back to the switch/control unit . i will take the most common fault with these , the test head light comes on when connected , all you do now is to swop a part at a time , like he control unit under the lamp and test , swop parts one by one untill it works , then you can order the part that needs replaceing with out guessing .

    Might be a silly question but you have checked the fuses?
