G30 BMW 540 headlight malfunction

Hello, I知 having issues diagnosing what the issue is with my passenger side headlight. So basically whenever I need to use my headlights and I switch the lights on, I値l get both headlights to respond but my passenger side will turn on but then turn off within a second. I値l then get all sorts of headlight malfunctions for the the entire passenger side of the headlight (high/low beam, etc). Anyone know what the issue could be, any help would be appreciated.
Thanks in advance!

Have you checked for codes? What do the codes say? Sounds like a bad module.

A bad module is the assumption I made as well, I did check for codes, nothing came up unfortunately!
