Moisture inside headlamps

[rayman86]

Hello all,

Quick question.. Picked up my c350 coupe today and noticed moisture on the inside of both front head lights? This can't be right can it?? Also what would you suggest I do about it?

It's mentioned in the manual. It's suggested to run the car with the lights on for (I think about) 15 mins and any moisture should disappear. If it does not then contact dealer for them to sort under warranty.

Yep, I had some in mine after a new lamp was fitted. Went after a long run.

You need to fix or change them because seal is damaged if you clean them it will appear again.

Did this resolve itself?

Found this in the manual - seems it's quite normal in certain conditions according to MB:

Headlamps misted up on the inside

The headlamps may mist up on the inside if there is high atmospheric humidity.

Drive with the headlamps switched on.


The level of moisture diminishes, depending on the length of the journey and the weather conditions (humidity and temperature).



If the level of moisture does not diminish:

Have the headlamps checked at a qualified specialist workshop.
