Help! 05 Mini Cooper S xenon dipped beam not working

if the ballast unit swap did not work then try the bulb

Do you have a photo of the Ignitor? It would be good to confirm the design of it .

IME the ballasts rarely fail and will cause a flickering, like you are experiencing.

Your problem is most likely to either be the bulb or the ballast pack if you have a flicker. I hope for your sake it's the bulb, as it's the cheaper and easier thing to change.

Have you switched the bulbs at all?

The reason I mention my E46 is that it uses the same ballast pack as a Mini ; the replacement/spare I have is from a Mini and has the same part no ; it was cheaper .

If you are local to Warwick, I'm happy to lend a known working bulb and a ballast pack. The ballast packs are around £50 secondhand and fairly easy to come by. I also have INPA which may show what wiring fault the car sees at the headlight, if there is one.

Both me and a friend noticed quite a difference just by going to new OE HID bulbs ; The M3's headlights now are very good with new bulbs. With Osram Nightbreakers, that different is even more but of course they cost a little more.
