Halogen headlights not working

Hi all

Not had time to search as at work

Wife just been in touch to say headlights not working properly on our 2011 D4

Dipped and high beam are not coming on either automatic or manually set.

LED ‘signature’ lights coming on ok, and strangely the high beam does come on for manual flash, but not when stalk pushed forward for constant high beam.

Hoping it’s a fuse, but ……

Any thoughts?

Kind regards

Andy

How long did it take for it to find it's dummy and stop crying about things?

Checked some random relays just now (I know they aren't really related but thought I'd go through some anyway).... all ok there.

Checked bulbs, connections to light cluster... all ok.

Question now - this MOSFET system - there's no real way of assessing if this is causing both my dipped beam to stop all of a sudden? And no idea where or how I'd trace back the wiring for a potential short.

Any clues?

it “could” be all the things that have been pointed out. But why hasn’t the single most delicate part been tested first?? The halogen ballast…

Halogen ballast? Is that not just for Xenon headlights?
