Misty PDLS

[Robograd]

Hi
Need a little help. My PDLS lights have horrible lower hemisphere condensation. Is this ok? Normal in the winter, according to OPC - I don't think so!
Experiences/Comments, gratefully received.

Normal for front and rear light clusters.

Many thanks Twinfan,
In all my years of Porsche ownership I've never had a car that's come over all misty in the lamps - it must love me!! A couple have filled their rear light units with shed loads of water though.
Cheers.

Water isn't good so I'd get that checked out. Mine mist over but that's normal as they are not fully sealed - there are drain holes.

If water is pooling in them there may be a seal issue so I'd get them checked.

I don't understand why Porsche can't get this right... Other manufacturers seem to be able make lights that don't mist up or suffer water ingress

What car? My 997.2 doesn't.

It's not a fault, it's part of the design. I have PDLS on my Cayman GTS and they are Xenon lights which have vented housings. The venting is to allow heat to escape and as a result you get some light condensation when it's humid/raining. If the lights are on the heat will evaporate away the condensation, so you'll only see it form when you're stopped.

its the water in the rear housing, not mist, that is my gripe

If water is pooling then you need to get it checked out, as that's not right.

Mist normal, water no
