Re: Any K12LT Xenon bulb replacement instrucitons
Good question. I was hoping to check connections, as Xenon bulbs, to my understanding are more of live or dead thing as far as the bulb is concerned, but not so the ballast and the igniter. To the best of my knowledge, they are arcs between electrodes which live in a vacuum and like halogen, are sensitive to dirt, especially oil from skin or the petrol type.
I think the Xenon run started in the 2006 model. From what I have heard, BMW left the old 7.5 amp fuses in which blew regularly until it was replaced with the correct 10 Amp. size. But both the 06 and 07 manuals have the instructions for replacing the H-7 halogen bulb, which was not too difficult from the description, if your hands fit.
I was hoping to replace the bulb speculatively to see if it corrected the issue, but I have to get it out because the maintenance manual lists the old H-7 as the replacement bulb.
Have you or could you check your 2009 manual for "bulb replacement"? I am just wondering if it says more than remove the clip and the take off the cover, with a picture of the old pre-2006 cover which has no Phillips balast on the back of it. It would be nice to think that somewhere in four model years that BMW would have updated the instructions. But it could be they gave up on that early.
