My car's headlights confuse me

[ymerameha]

Hello

I get occasionally DTC error B14DA - Right Headlamp Light Distribution Actuator, Performance Or Incorrect Operation. I removed the headlight to look maybe I can see something, but there aren't very many openings or anything to look at behind. Only one relatively small hole behind electronic module (HCM?)

What if bulb needs replacement? Do they need any replacement?
I'm looking at the label - Full LED ADB. Are they really full LEDs? I was always thinking they are xenons.
Can I open the light case?

Is there any way to repair it or replace it with something else?

The new part costs 1750 EUR.
