I have the Xenons/DRL's and had this the last time I washed my car, but only on left side headlight, was in a simular position to yours along the bottom of the headlight. Havnt had any problems with them yet so just hoping it wont happen again. If it does i'll ahve to take it into the dealers.

Ya get the fogging up too, I asked the question here before. Its pretty shit in my opinion but it appears that the actual headlamp has a plastic cover that is not airtight. This condensation used to cause corrosion of the reflective surface in some cars. I wonder if it will in this case?
I also queried on here if anybodys lights shaked on rough surfaces, the light beam, not the light itself and a few people said that typically audi zenons do shake which again is not very good.

Headlights should be air tight!

If it commences to show signs of condensation, take it in to the dealer for replacement, its covered under the factory warranty! Don't wait... Time passes quick.

We've had the discussion before, there shouldn't be any condensation inside the headlamp unit.

If your dealership tells you otherwise, try another dealer.

You sure about that. The actual headlight cover just seams to be clipped on poorly and is not the type of construction you would expect for an airtight seal. I would have thought they should be airtight and if so, its two new lights for me.

It does appear that alot of people have leaky lights though.

No, the bumper does not need to be removed. The headlights are relatively easy to change. There are only 3 screws securing them.

I've had this problem with one of my 2004 A4 headlights, the bad news is Audi considers this normal and will NOT replace it according to the dealership. The good news is its' been happening on and off for the past 4 1/2 years and my lights still look and work great. Mine are Xenons with no DRLs back in the day of course.

I dont see how the headlights can be sealed as you can remove the bulbs which leaves a big hole in the back of the unit, which means that there is air in the unit which therefore means that there is moisture in there as well.
My A4 cab's headlights misted slightly for 5 years with no detrimental effect.
I have also noticed a slight misting on the bottom edge of the lights on my A5, it soon goes though.

Most manufacturers headlights dont fog unless damaged etc so the argument that moisture gets in when changing bulbs doesnt 'hold water'! The rear cover on most headlamps have an open vent and from memory the base plates on alot of bulbs have a small hole which would allow moisture past to be vented at the rear. Small amounts of moisture would never cause a problem but I get the fogging up after washing the car or on a wet day, leading me to think that water in entering around the light.

As you say, the units are open to the atmosphere so therefore have air in them.
This air will usually be a bit warmer than the ambient air especially if the engine has run in the last few hours, if you then cool the outer side of the headlamp cover, eg by washing or rain you will get condensation on the warm side, just like you do on the inside of your house windows in the winter.
I used to get it on my BMW as well. I might add that it has only ever been a light misting and doesnt last very long.

I have this issue as well. Does anyone have any experience of addressing this with a dealer? If so what did they say? I never had this problem on my A6. Is this something that can be fixed?

Any help is appreciated.

it happens sometimes after a wash, but the vents in the light clear it up pretty fast...

Happened on a buddy's Cayenne Turbo, same thing after a wash..

I took delivery of my audi yesterday, drove it home and noticed this problem

It's gone today but I'll keep an eye on it. Good to know I'm not alone but it's odd that some people are living with this and others are getting replacement parts.

This normally happens in the first week but then should go away and not come back. If the problem persists then get the dealer to sort it.

I had this for the first 2 days, spoke with the dealer and they told me that once I had driven the car a bit the heat from the lights would sort this out and it would happen again.....and this turned out to be the case.

Thanks SAJ_1982. That gives me some piece of mind. It sucks when you bring home a new car and immediately notice something wrong with it. My eyes are particulary sharp for small faults (someone with dirty hands grabbed the A frame by the driver side of the windscreen and left a dirt mark )

No the A5/S5 head light is not air tight in fact there is an air vent on the back of them...the vent could be blocked and that would cause the glass to fog up. I had that problem when i stock the eropean headlights in my american A5.

Bring back this thread...

I noticed condensation along the bottom edge of both headlights as sj1 described. This happened to me on my STi during the first week or so of ownership... and never returned. I hope this is the case for my 5.

Is the consensus that if it continues after a couple of weeks that it is, in fact, a problem?

I noticed only once during my first few days of ownership that there was slight condensation, but never saw it again.

It was drizzling on my way home from the dealer, hopefully I don't have to see this again... I've seen first hand how water can ruin headlights before, and I def don't want to see these beautes ruined too.

I have had this on many cars with Xenon headlights and each manufacturer has said the headlights are designed to "breathe" as they have vents in them the misting clears depending on atmospheric conditions and that has always proven to be the case whether its Porsche, Aston Martin, Range Rover so I wouldn't worry about it

I got the dreaded condensation today in both my headlights (worse on the passenger side). Its been pretty dry here lately and then it cooled down and rained a lot (and I got a car wash)....making the perfect conditions for condensation.

I took the lights out (since its so easy) and blew my hairdryer through them for a few minutes and it cleared right up.

They are definatley not sealed. There is actualy a vent with a rubber hose near the top-outside corner.

I hope this doesn't happen too often...
