Headlight Condensation
Last night I was driving on a very poorly lit back road and I drove through a huge puddle that I didn't see in time to avoid. I noticed this morning that both headlights have some internal condensation..even the eyebrow portion. What's the best way to get rid of this? I've never seen this before.
My driver side rearview mirror turn signal has been filled with condensation for a while now, I just haven't bothered to drive to the dealer to get it fixed..but now this? hmm..

I just put the headlights on and I'm letting the car sit for a while running. The condensation seems to be clearing up slightly. Hopefully 15 mins or so will cure it..

Put on your "who, me?" innocent face and ask your dealer why the lights are fogging up. Don't mention the dousing.

Its just a little bizarre that the car is 9 months old and this issue appeared out of nowhere on both headlights. I've driven through much worse conditions than this before. I dont feel like having to deal with this on a 2009 Mercedes.

Step 2, if that doesn't work, remove the bulbs and stuff paper towels in there till you've got it all dried out.

I've just a similar occurance, but nothing to do with a puddle. there were no mitigating circumstances in my case.
Popped along to the Dealer and they apologised a lot saying they would just like to replace the unit, but MB HQ apparently claim this problem doesnt exist.
So jist of conversation is that MB deny the problem exists. i.e. the fallacy argument, but they may replace it under goodwill
hence, the dealer has taken photos and it sending them off to MB under 'goodwill' despite car being under warranty.
Unless of course MB call it goodwill so they can still claim problem doesnt exist.
Car has Xenons and Intelligent Light System if that is any help. The problem only exists on the drivers side (right hand side). The other lens is clear with no issues.
Apparently, the way Mb diagnose this is to leave the car running with all beam lights on for 20 minutes. I have tried the 20 minutes with both lights on (full beams), and it does make a difference so you may want to try that. Suprisingly Dealership didnt say or try that. Not enough of a difference in my case though, water is still visisble, so still going to wait to hear from the dealership

headlights may look sealed, but driving over heavy puddle of water can still cause water to get in.
take off the main bulb cover and take a blow dryer to it. make sure everything is dry. it'll definitely take longer than 20min. I had the same issue on one of the bi-xenon on my 203 and that did the trick.

Definately try taking it to the dealership, but do you have aftermarket HID's? If you do they may claim MB-USA isn't liable for that because you compromised the headlight from drilling a hole in the dust cap.

When it gets colder you condensation will appear again trust me its common problem when you install after market HID and seal not properly installed. It occurs when air has more water vapor than it can hold. Excess water vapor (a gas) condenses into water droplets. Air may be cooled until it reaches a temperature, known as the dew point, below which it is unable to hold all of its moisture in the form of vapor.

Just now noticed that you're talking about the headlights and not the fog lights.
I had a similar experience with the fogs.
That must have been one heck of a puddle for you to get that much water into the headlights.
