Last night when I started to come home from work, the right headlight blew.
Went to change it this morning, still not working
Hi beam doesnt work either
Any ideas of where to look next greatly appreciated.

Thanks

Fuse maybe? Got - 2017 SDV8 Autobiography in Loire Blue

Fuses?

No fuses for the headlights, they are protected by mosfets in the LCM.
Having said that you could check fuses 4 & 9 which serve the LCM.
Are you sure the bulb failed and not the ballast?
You could try swapping bulbs left to right and see what happens.

The OP has an Aussie HSE so will most likely be “halogen” headlamp bulbs ndfi...

So he has. No ballasts as a problem then but the filaments are still protected by Mosfets. Not sure why both filaments should be off in one headlight though. Possibly worth checking the earth to the headlight. Maybe even do a battery disconnect/reconnect and see what happens.
After that it would be worth checking on diagnostics.

Plug on the lamp unit? Regards

Would say it's likley to be something specific to that light. There won't be a fuse or mosfet specifically for one side?

So as above check the bulb holder for corrosion on the contacts.
Check the pins for voltage.
Check for continuity on the ground wire between the body and the ground pin. There is nothing that can't be fixed with a hammer😜😜
