To save weight, the Golf GTI Clubsport S does not come with an emergency inflation kit or spare wheel. See VW0926-16 for more information.
Sorry I understand you are the messenger of this info but this is a poor response, if VW wanted to save weight they could have left out any number of items, Nav, radio, heated seats, Air con, 19 Prets, light and sight pack, added a smaller 1tr washer bottle if they wanted for the figures, then allowed customers to add to the weight with what ever options they wanted. The headline weight figure would still be intact, but to leave out a method of moving the car if you get a puncture is ridiculous. Lots of lightweight cars have been made over the years and most if not all came with this basic feature, R26R had tyre foam, some even came with spare wheel and tools (964 RS).
I can't understand why you would have Discovery Nav in a car you wouldn't drive very far just in case you get a puncture...
