One of the headlight lens on my 2001 Audi A6 Quattro is all fogged up. Can I purchase the lens separately or do I have to buy the whole headlight assembly? Is this a DIY project w/no special tools on hand?

 

Is there actual moisture in the lens itself?

 

there is a DIY floating around somewhere i cant find it tho...

 

My halos fogged up as well, apparently what the aftermarket companies do is crack one of their seals so we have to go buy a new set through them as a way to make more money. Before you go and take apart the light, unscrew the light so its out of the car itself, take a hairdyer and dry out any of the access moisture, then take sealent, and reseal the whole light along the seams. Its exactly what I did, took about 10 min, and I haven't had a problem since.
