optional extraLeather became standard on the GTI right at the end of their production life and Im not too sure on the heated seats. Im pretty sure it wasn't part of the winter pack which is headlight washer, heated washer jets , heated wing mirrors and low level sensor on the washer fluid which would make me think the heated seats in cloth and leather were standard, again not 100% im afraid.
As for the privacy glass im not 100% sure that you could get that out the factory, at guess Id say yes as an extra but not too sure.
The colour coded bumpers were not an option and only come fitted to the Edition 30 GTI which was brought out to celebrate 30 years of the Golf GTI.
On a side note I simply refuse to believe that your BMW came with anything as standard apart from the doors and the steering wheel
