Foggy lights

Just nipped out this afternoon, and when I git home I noticed my headlights were partly foggy.

Surely this shouldn't happen? Any thoughts?

They are not sealed units so will be subject to the physics of weather.

I had this on my car with the PDLS+ headlights. took it to the OPC the tech told me that they were vented with a small tube, if the fog doesn't go away after a decent run ie 30 mins or so there may be a problem. Since then I have not worried about it!

This is taken from the Porsche Good to know app:-

Information

- If the driver's key is removed and the door is opened when the lights are on, an audible signal (gong) warns of possible battery discharge. In some countries, differences are possible due to legal requirements.
- The vehicle’s exterior lights can mist up depending on temperature and humidity. This misting will evaporate after a sufficient distance has been driven.

Or, in other words...

"They all do that sir."

You'll get used to this OPC mantra.

Mine go like that when washing the car, thought there was something wrong when it first happened. But they cleared shortly afterwards

Thanks for the comments.

Yeah, all Porsche lights across the range are vented as opposed to sealed units and misting, especially this time of year, happens constantly.

There are acceptable levels of moisture according to Porsche

I’ve had 4 rear lights on the 911 because of this - having previously been declined
