fogging C63 lights

[Castor79]

Evening,

Driving home tonight in the pouring rain we have noticed that the front passenger side headlamp is a little fogged up on the bottom part of the lens, closes to the sidelights. It's only on one side so I'm wondering if this is something others have experienced - can't say I've noticed when I've washed the car up till now... or any cracks or damage to the lamp?

Couldn't seem to find any other threads on this

MB will tell you it's not a fault.

There are vent tubes on the rear of the headlamp units, check they are clear. The fogging is simply due to the relatively high humidity and cool surfaces.
