Hi guys, my passenger headlight started to fog up and i can see droplets of water inside. I'm looking for a guide/tutorial on how to remove the headlight, i will reseal it. Any one know how to take the thing out?

 

If you're talking about condensation under certain conditions, I wouldn't worry about it just yet.

This would happen all the time when I hand-washed my W204 C63. Would go away on its own as soon as I started drying the car with a gas-powered leaf blower.

You can do a search, but condensation that appears during heavy rain or washing your car and then clears up on its own is normal for most of these cars.

 

Especially if you have the exclusive lighting package these are more prone to condensation...its normal & will go away after leaving them on for a bit.

 

Absolutely normal unless you have the actual water inside

 

I have the same in a brand new car. How is this normal? Never had this in RS3/RS6

 

It is fairly normal in high humidity situations (as there is venting built into the units). Happened more in my Audi and Range Rover than they do in the Merc though.

If the moisture doesn't clear and droplets stay then you may want to get the seals checked.
