Hi all friends,
after washing my car I noticed that I have some condensation on both headlights.
I left the car for a few days in the garage but the problem did not go away and condensation is still present on both lights.
The car (MY2019 2.0 P300) has 25000km and 3 years of life.
The warranty has expired...any way to fix it by myself?

Very thanks

 

Try turning the headlights on. I dunno if our headlight assy's have vents but maybe the heat will dry out the condensation.

 

I've used a shop-vac to dry out the inside of headlights before. They had a separate high and low bulb, so I took both out and taped the vacuum to one and let it draw air through the assembly. With the car parked so the light was in the sun I let it run for a while and the moisture evaporated. There were two things it didn't do though. It left some spotting on the inside and it didn't seal the assembly where the water got in. It turned out to be an issue with that model (Subaru Forester). I ended up replacing both assemblies, but by then aftermarket were available. I doubt we'll ever see aftermarket headlamps for this car.

The WRX kids liked to take their headlights apart for a particular appearance mod. I think they used an oven on warm to soften the seal on the lens to remove it, but don't trust my memory on that. I've never heard of anyone taking these apart. I suppose the repair depends on where the water got in.

 

Not as likely with the LED headlamps. No heat generated by the LEDs, you see. But, its worth a try to drive around with the lights on for an hour. (FUN, too!)



Our HID housings will get a little condensation after washing, once or twice a year. They DO need a bit of ventilation.

On other cars I have removed the offending light assembly and smeared a bit of flowable windshield sealer (aka Permatex 81730) on any seams.

 

after I left car in the garage all night, the headlights were no longer fogged this morning.
however after one ride about 10 km on the evening the condensation on the headlights reappeared. probably due to the difference in temperature between the inside of the headlight and the outside. I don't think this is normal…someone has changed them under warranty?

 

Dont worry about it, my 2018 does the same, it's just condensation from different temperatures, it just happens

 

Hello! Same on my 2013, w/o having generated other visible issues throughout the years - so hopefully a minor problem, have a nice Sunday!

 

I noticed a little condensation in mine today after a run today. I was buying wine and picking up an order of handmade chocolate so didn't want to kill the mood by investigating today. It was not nearly as much as the picture in this thread so is likely "normal." The assembly does have a vent to keep pressure from building up inside (or out) so some moisture is inevitable.

 

Does anyone know where these vents are located?

 

I just went out and looked at the back of mine. I did not see what I expected to find but perhaps it's just not visible without removing the assembly. I can't imagine that there isn't one.

What I was looking for was a small rubber fitting that didn't have anything connected to it, maybe with an upside-down "J" shape that would keep out water but allow pressure to equalize. I even looked at some eBay assemblies to see if I could spot it, but no dice.
