Hey, I’m new to the group so if I’m posting this wrong, someone let me know so what I have going on is my passenger headlight caught fire somehow and it burned up a few components I will attach the pictures that I have my hood is stuck so once I get there for you, I will get better pictures what will be some steps to take for DIY and is it possible.
The car still runs fine no overheating and any other issues besides light warnings
Ouch, hate to see that... If you look inside your car's other headlight, you will see that probably 30-60% of wiring insulation has crumbled to dust, resulting in a bunch of bare copper wires barely not touching each other and shorting out.
This is common due to heat, and the fact that mercedes had a weird eco-friendly wiring fetish a couple decades ago, meaning wiring insulation would just crumble away after a while. This only appears to affect headlight wiring in our cars, but the 90's v12 cars would have their entire engine wiring harness disintegrate, totalling the whole car.
When I discovered the wires in my headlights, I spent several hours carefully wrapping each wire in electrical tape, then zip tying all the wires together in a bundle so the tape wouldn't fall off.

it suck but it’s not a total loss.. can someone help point me in the direction of where to find a list of all components and part in that area I also have more pic with the hood up I will attach later
Mercedes has a site (just google "mbparts mbusa") that'll more or less provide you with parts diagrams that'll be a huge help. Crack the hood open and see what looks crispy/charred, and take good pictures from several angles for reference. After that, buy the expensive parts on ebay, used. Probably wanna try and buy a used passenger headlight with the exterior part of the wiring (connector that plugs into the headlights) connected, rather than just try and find a headlight and electrical connector separate.
I'm guessing fender, wiring, windshield washer reservoir, maybe a cooling/radiator hose, maybe coolant reservoir, front wheel well fender liner, maybe intercooler pump, maybe ABC level sensor (attaches to the top suspension strut). Check the ABC line to the strut, and make sure the rubber hose isn't burnt, since that's a 3000 PSI hydraulic system.

thanks that’s some great help I really appreciate it I’ll start with cleaning up and figuring everything out
I'd definitely replace the pressure reservoir, it'll probably explode because it looks like it got some fire damage. Those 2 hoses that went into the windshield washer reservoir use system coolant to heat the washer fluid, so make sure they're OK. Probably gonna want to re-tape all those charred wires at the very least. Make sure none of your plastic idler pulleys are crispy.
TBH, you're lucky it was that side and not the other side where the ABC pump, reservoir, and AC stuff is.
I will start there at least with cleaning up and get exposed wires tapped up I will keep yall up with the project I got this car for a good deal with low miles I currently looking for someone parting out a cl500 to get as many part I can of it to replace
