The Pilkington screen as others confirm is identical, I have one outside with Pilkington and other with original screen with VW logo, the logo is the only difference, tint, clarity etc are the same.
If you really do want a VW logo screen then Autoglass for instance just note your request and send it for approval from your insurer, normally no issues I was told, same excess cost only thing is you have to wait a few days for it to be approved and be delivered to your local Autoglass outfit
