Hi guys and gals

Got a issue with my main beam and flash in that it doesn’t work . My head says fuse but I can’t find anything in the book that points to main beam and flash .
I’m thinking it may be the fuse box underneath the glove box but just wondering if anyone has any other ideas ? It doesn’t come up with an error code and does not show the main beam light on the dash 2002 - Blue L322 3.0 TD Vogue (Previous)

ive had a look at the wiring diagram, the body control module switches the main beams on and off, there are no fuses or relays.

its unlikely both channels of the BCM have gone at the same time, so the most likely culprit is the main beam switch on the steering column.
