Rear quarter glass micro cracks

[Seatdownhere]

Hi

Was wondering if anyone has a similar situation. Only noticed this yesterday after getting car back from service.. was almost ready to blame them as I thought some impact had taken place.

There are tiny micro cracks across the rear quarter glass. Can't feel anything with my fingernail. It's only really visible in bright sunlight. Is this the tint that has cracked? And if so, how?

Mine doesn't look that bad but I can see what you mean. It's plastic though, not glass, may be it acts / reacts differently to the elements? Or you've only just noticed how it looks now.

If it's plastic it's probably UV damage

every leon i have seen has exactly the same.

Exactly the same thing happens to the polycarbonate headlights in most cars too. its UV damage.

Looks crap but can't be helped.

Check out "headlight restoration" on youtube, you can remove the UV damaged/oxidised layer quite easily from plastic.

Thanks so much for the replies, guys!

It makes me feel a little better to know this is a common thing on these cars!
I must not have noticed it before (bought the car in October last year, and the weather's not been very sunny since!).

I thought the fact that they are the tinted version would prevent UV damage. 8 years could override that though I guess.

Had a quick look on YouTube, and saw some videos - but I don't think those methods will work on tinted polycarbonate.
