Moisture in o/s headlight

[sam4191]

Hi guys.

I washed my car on Saturday, no different to how i usually would. I went out in the evening, and noticed that the O/S headlight was fogged up on the inside. It keeps clearing and re appearing now. Any idea's on how i can clear it. I have looked, and there is no obvious way any moisture would get in! =S I have facelift headlights if this helps.

Thanks

How are you washing you car? is it with a pressure washer? may have a small crack/hole somewhere, they are quite easy to remove to inspect further

The lamps are actually open to atmosphere.

Theres a little vent thing underneath, so they can fog up from time to time.

Audi will usually tell you to sit with the main beam on for 10 mins to dry them out.

cheers for that info aragorn, must be using a pressure washer and aimed around there?

 

[aragorn]

aye, maybe even a hose would do it.

Ours sometimes fogs up in heavy rain.

 

[sam4191]

No, I use a hose.... just chucked a bucket of water over it to rinse it this time though. lol

Oh right... Thanks for that Aragorn... will give it a go! Will let you know the results...

Mine did the same the other week. Was really puzzled. Not done it again since.

Is that why you set fire to it, to dry the headlight out, a bit extreme, hey !!:icon_thumright:

Funny!

When I first got stinky and she had the bosch pre facelifts they were a mess. Really dull and starting to go green. After a bit of examining I found out that the glass can come off the older unit and be cleaned. There's a rubber seal around the lens (carefull, one of mine almost broke) and lens just comes straight off. After a good clean they were excellent... This may allow you to get in and see if there's any water trapped or if the breather hole has become a bit bunged up.

i had this problem on my car so i removed the black plastic cover on the back and left it to dry out for a few days then i ran a bead of silicon sealant inside the covers seal and put it back this was 3 months ago and it as not happened since its worth a try

 

[dieselfitter251]

Sorry, just realised you have facelift lights.... still. Not sure if the plastic lenses come off the facelift units?...

Not without a lot of effort with heat guns, screwdrivers and pliers.

 

[sam4191]

Thanks everyone!

looks like it's not a rare problem! Shame it's not that easy then dieselfitter! and well done one the 250k by the way!

Have sat with the full beams on for a while, a couple of times now, but not much happened. Will take it out have a look i think! lol.

Sounds like a plan!! lol! Lovely looking car by the way eatdegrub!



I hairdryer'd it the other eve. Most of the moisture has not gone, could do with another 10 mins, but til we have some nice weather... twill do! lol
