Having just been sorting out my car ready for my trip to Austria on Sunday I have made a small discovery that may be useful to others. My A3 has the dreaded 'space saver' spare, so to counter the possible of a puncture crossing France on Sunday when all the garages and tyre depots are closed and having to cover hundreds of miles on a space saver at 50 mph, I have purchased a new steel wheel and a matching tyre. I was looking for some kind of plastic bin liner or similar to put the wheel and tyre in so that I could carry it behind the passenger seat - no room in the boot for the journey there and back because of the luggage. None of the bags I could buy were big enough. But in the foam holder inside the space saver Audi have provided a large clear thick plastic bag for just that purpose. Very thoughtfull.
