Headlights haze on glass

[Monsoon]

My headlights seem to have millions of tiny micro-cracks on the inside of the glass units which are particularly noticeable when the lights are on. Anyone else got this or got it sorted?

No moisture/condensation evident, no obvious gaps/leaks, and thoroughly clean on the outside. The car is now 6 years old.

Thanks

That's not good.

Chiming in to say this is exactly what mine looks like. 2014 mk3 Cupra. I'll post images shortly.

There's a whole thread on here about this. I'll try find it. Think it effects pre facelift LED headlights.

Hopefully someone from there can help.

Thanks Kirky. Looks like a not uncommon problem, but no one on that thread managed to get it sorted. Would be interesting to find out if anyone has since then.

I expect so.

I think my previous Leon 08 mk2 had similar on the headlights, didn’t seem to affect the light pattern or mot.

There probably isn't going to be any sort of easy fix for this I'm guessing, either bake the headlight so the glue melts and you can separate the lens from the unit and polish the inside of the lens if you are confident enough.

Otherwise replace both lights will be the only other option.

some of the earliest model suffered from wrong filter fitted causing dust getting sucked in the light and this is exactly what you get after couple years running the light. SEAT wont take any warranty measure on this problem only one solution is replace the light if you not fancy baking and taking it apart.

Of all the VW Group marques, SEAT do seem to be the worst offenders for many "lighting assembly" problems when you include the leaking/falling apart rear light clusters, I can't quite understand why that is happening again and again.

Just posting my example as I said I would. Not the best picture but I feel like it's the same issue as described above.

My facelift lights look pretty much the same on a 2 year old car, but in my case, on both sides the auto-levelling has decided to give up often, requiring me to turn engine on and off for lights to level properly, so I am hoping they will replace both under warranty - currently case is under investigation and my local dealer is seeking approval for the repair.
I believe their solution will be to "first attempt a reset of the leveling system"
I needed to provide video proof, including the car license plate, for them to take action.
I feel I have a long fight ahead... But hopefully I will get the full lights replaced, which will sort also the foggy lenses from inside.

So why we have cars under warranty?Video evidence sometime not enough and never ending argument really tiring.

If I would count all the times I complain about something only to either be told "it is normal" or simply ignored...

Did anybody sort this out? Mine seems to have developed this on the drivers side out of nowhere

Any one found a fix that does not involve buying new ones?

Are you guys sure it’a on the inside? I have the exact same issue and saw people on other groups just getting rid of the old clearcoat and applying a new one.

Looks amazing, what did you use, and how hard did you hit it with the sanding?

 

[sebastian.p]

It’s not mine, borrowed from the other group. I’ll probably give it a try when it gets warmer in a few months. There’s plenty of videos on YouTube showing this. Just wanted to hop on and maybe resolve the issue for some people, cause I at first was also sure it’s all on the inside.

I see, thanks a lot anyways, I plan on giving it a go at some point aswell. I read somewhere, that it takes rougher sanding than one would think.

I tried it on one of my lights so far using various grit wet & dry attached to a drill. Took me the best part of 3 hours on one light. And it's largely worked a treat. I'd definitely take a bit more time stepping up between grits to ensure there are no scratches left behind.

I treated it with Meguiars Headlight Coating as I heard that's a good cheap coating that will stop this happening again. I also bought PPF film for the headlights from https://chronlakier.pl/ which I understand is a good UV protector of the headlights.
