[Giray]

It's more than likely the windscreen Giray, especially if you've had a new one at some point. They need sealing with non setting windscreen sealant when they are fitted.

Its still the original windscreen but now that you mentioned it i will check it out sometime hopefully thats the problem and i will sort it out. I had a look around the screen didnt see no rust or anything but maybe its what you said. Thanks by the way

If it is Giray, the only successful way is to remove the screen, clean the rubber if it's in good enough condition, treat any rust around the opening and refit the screen with sealant both around the glass and around the correct part of the body aperture. Sounds a lot but it's not too bad a job. The water often gets in at the corners of the glass where the rubber on the inside is lower than the rubber on the outside. Blocked or broken sunroof drains can cause water ingress too but this is easy to sort and it's rare the drains get broken or disconnected.
