Can't figure out Headlight issue I need to safety car
I recently purchased a car I have been looking for ever for. A 2016 E250 Fully Loaded.
It has Distronic Package, LED Package, Premium Package, AMG Exterior Package, and everything else besides massaged seats.
I have a week's permit to solve the headlight issue and cant seem to fogure out what the problem is.
It has the Intelligent LED System headlights.
The Drivers side:
DRL do not come on,
Blinker does not work,
Side marker not working,
High beams not working,
But when I switch the lighting to ON the two beams in the middle come on.
Buzzing sound coming from the headlight even when car is off.
Passengers Side:
Blinker works,
DRL works,
High beams not working,
But the two beams in the middle do not work.
I would hate having to replace both headlights as they are quite expensive, I'm wondering if there is a fuse that could've burned out or a module I need to replace. Or how I can diagnose this. Image files too big and cant upload, google drive link with attached pictures and video: Link to Images and Video

pointers + tips...
Congratulations on finding this great car with all your options including my favorite... Distronic!
Headlights problems are a real nightmare with these networked LED.
These headlights work in tandem and speak to one another master/slave style. Unfortunately their control modules may get be affected by rain, carwash or moisture - They require to drop the bumper and use Xentry tool to work on.
So it's fair to say they are not DIY friendly.
With all that being said you can try ...:
-- a 10Mn battery reset
-- cleanup nearby GND posts
-- scan for fault collection
