Hi chaps. My n/s bi-xenon has gone out with the bulb failure light in the driver warning panel. I've got VCDS. Can I diagnose what's gone using VCDS, or is it pretty obvious what it is? Basically normal beam is off on n/s, but hi beam works fine both sides (although there's a blown sidelight too on n/s)

I'm not familiar with xenons, so any help will be most appreciated as always.

I take it I'm correct thinking it's bi-xenon? Pic attached
