Hi all! One of my headlight not working most of the time and when is working its flickering.. anyone know what is the problem.

Mine did the same on my E93 which uses the same Xenon bulbs, had the bulb changed out and all was well.
I believe it's the igniter that's built into the bulb that's at fault.
Garage charged me £70 for a new Xenon bulb, they had to remove the wheel arch liner to access the rear of the headlight, not sure if this is necessary on the F25

Will this be cover by warranty

Got to be worth a try.  It will depend upon whether BMW class it as a ‘wear & tear’ item - which IMHO it should not be if within the first 3 years as HID lamps should last a lot longer than that!

Definitely sounds like an igniter fault (electronics failure) rather than the bulb wearing out.
