Fraser, you'll be wasting your time.

Most of the VAG group has this problem from 1.0 ltrs Arosa's to £65,000 RS6's

they will tell you to put on your lights for 1/2 hours to clear them.
Been there done that, still the same.

Theres alot of manufacturers have this problem and none of them will do anything about it.

One of the best ways to fix this I've found is to sellotape a couple of packets of silica gel (the type that says do not eat on) on the inside cover of the headlight.

Had to do this on my old corsa, worked a treat!!

Mine had moisture in when I bought it, took the back plates off and cleaned up the rubber seals, used some Autoglym rubber care on the seals and the moisture never came back once the headlights dried them out.

The silica idea is good though :)

its caused by the air being at a different humidity and temperature, i drilled some small holes on the bottom of the black cover and put it back on, never happened again. because it allows the air in the lights to change with the atmosphere outside.

Like jayt said, it happens when the glass is a different temperature on both sides. It's the same thing that happens to your windscreen on a cold morning..

Make sure you do it on a dry day too, and leave the covers of for a bit to let the fresh, dry air into the headlights before slapping them in.

At my garage we spray brake cleaner into the light then blow it out with a air hose till dry that what we do on our vauxhalls that have condensation.

ive had no problems with my lights after drilling the holes, i only done two holes at about 2mm in the bottom of the cover, its just to allow air movement,

I had this problem after installing my HID's and it sometimes comes back after washing my car. BUT I’ve found a solution that works Great! You know them silicone sachets that you get in shoe boxes...well take your side lights out of its fixture and put the sachet in halfway so it sits on the rim (you may want to thread some string around it so it doesn’t fall in). Leave it for a few hours and then the moisture is all gone.
I'm also going to put a rubber washer around the hole I cut on the light cover for the HID's so that gap isn't too big. But them sachets are a definite winner for getting rid of the moisture.

dealership will just use an airline to dry them and send you on your way -- at best you'll get a tiny hole descretely drilled in your lamp and be told they have modified them for you.
common prob on alot of makes/models etc. reason is very well described above!
