Headlight glass cracked

Hi everyone,

Yesterday afternoon, while washing my car, I saw that the right headlight glass had a crack, from the top, starting from under the bonnet, and going 1/3 of the way down.

No other signs of anything hitting the glass or anything near, it looks like it has appeared more or less by it self, perhaps from internal stress forces in the headlight glass? Of course this is difficult to tell.

In any case, do anyone here know if it is possible to change only the glass, or do I have to change the whole headlight? I want to change it, as water has already started to get inside the unit.

The car is an 2007 model, facelift, with HID lights.

I will talk to my local Skoda dealer on Monday, so we will see if they will accept this as a warranty issue, or if my wallet will suffer... I am afraid they will not accept this as a warranty issue, what do you think?

Thanks in advance for any info.
