Most VW dealerships hid the "build sheet" within the vehicle! with a bit of luck, yours is still there! fold the rear seats forward, as if your going to carry something large in the boot, this will expose the end of the floor carpet, that disappears under the rear seat base,
slide your hand under the carpet, and have a feel around for folded paper, like your looking for hidden money!! if your carpets have never been out, then there's a good chance its still there, the build sheet gives a full spec of the vehicle that was used in the factory, only in a code form, but luckily includes the paint code... I have actually seen build sheets taped to the floor, under the rear seats..
