Here is what my passenger side light looks like. The drivers has nothing. The service manager at Carlton Mercedes in Greenville SC says this is normal and there is nothing Mercedes will do about it. I’ve argued it’s not normal but he doesn’t care and I’m currently trying another route to get it fixed before I pitch a big fit. I also haven’t had time to drive the 1hr (+/-) time to the next dealer to have it looked at.
Please let us know what you find out.

Yours is worst holy cow! Do you have the multi-beam? I am curious to see what will happen if I turn on the high beams and let it heat up for like 1 hour. I have seen a posting on the S-class forum that there is a "fix" for this problem which involves a absorbent pad or something. It is known to MB and there is a service bulletin for it. https://mbworld.org/forums/s-class-w...-lights-2.html
Reading that S-class thread makes me wanna say, "give me back my Xenons!".
2 days ago when it was a little dry I see residue inside the lens. If the moisture goes away and the residue is still there I will argue a replacement. On my c-class they replaced both headlights before when there was a residue after a moisture build-up and the new lights were fine afterwards. If I were you document both sides of the headlights at the same time and when the problem does not go away time to call MB about it. I already texted my service adviser about it and will let you know what he will say. If he does not do anything I'll call my service manager friend and tell him to pull some strings and get it replaced.

Yes I have the upgraded headlights. When mine does ever dry out, I don’t remember seeing any residue. I’ll read through that other thread and see what it says. Again, I find it hard to believe this is normal for our cars in this price range, but really, any cars nowadays.
My other route at the current time is A. not dealing with my MB dealership. B. not wasting any time with MBUSA, yet. I still think they are pretty much worthless since all they do is call the dealership and basically say a mad customer called them. C. trying to get an insider MB person to help me out and get it ok’d to change it out. I mean after all, if it’s normal, why isn’t the other one doing it.
Apparently, MB issued a recall on MY21 GLC 300 for the same issue. Perhaps you can use that as ammunition when you speak with dealership. See attached....

This appears to be a common problem across all car brands. I wonder if the newer LED lights are more susceptible because they don't get as hot as the older HID and Halogen lights.
Had the same thing on my unit 6 wks into ownership. They addressed it with no argument
It's a common occurrence in the automotive industry. I've worked for an OEM over 20 yrs now.
Unfortunately, you run into idiots at the dealership who insists that's how they all are.
Escalate it to the District Service Mgr.... if the dealer service mgr doesn't want to make that contact, call MBUSA and threaten to invoke lemon law
