Nope, not seeing any so far after about 3800 miles and significant temperature changes.

It's supposed to be normal from what I heard. When I first got my car it had some condensation on both sides too, but I haven't seen it since.

I've had some, in Northern CA..with the upgraded lights. I don't think the pod is a sealed unit, not completely so you're going to get some condensation when one goes from hot (most likely beams on) to a colder garage and let it sit.

The one thing I have noticed though is these LED headlights just don't melt the snow & ice off like HID lights do cause they don't get as hot obliviously.

You're certainly not the first. This has been reported a few times by others .. e.g:
https://mbworld.org/forums/c-class-w...fter-rain.html
https://mbworld.org/forums/c-class-w...densation.html

If minor, it's probably normal for certain conditions, but if you have it all the time I'd get it checked out.

well, today headlights weren't condensated at all.

I guess it was from the rain.

my guess would be that the headlights are not sealed 100%. might be due to having LED light option.

not too happy about seeing foggy headlights on a brand neew car, specially one @ this price.

but thank you for the links to the thread, at least I don't have to go for service anymore.

I had major condensation during the rain in one of my headlights. I have the standard headlights. It's a well known issue. I took it to service and they decided to replace the headlight unit.

I've never had this happen on any previous Mercedes.

I see this on my BMW and MB from time to time in damp weather.

It always clears on its own and is of no concern.

I see this a lot but am not worried. The led lights produce no heat to speak of and I have noticed that the lights mist even when the car has been parked all day so it is not related to headlamp use rather just atmospheric and temperature conditions.
