Of course it can be used many timesNot in the UK its not. I rang 3 Audi dealers when I realised my mistake. 2 said it couldn't be done even though I sent them the link to threads on the internet where people had done it. Another quoted me £1200!
I don't have a spare, but even if I did my first option would be to try and inflate the tyre and drive slowly to the nearest repair centre. This should work for a typcical puncture e.g. a nail, provided you do not remove the nail. Never drive on a flat tyre, or you risk wrecking it and the wheel.The other thing I wondered was, if I got a puncture and it was a 'slow' puncture would the inflating device inflate the punctured tyre?
