Having checked today, the tyre sealant in my 2012 RS3 went out of date Feb 2016.
Rather than pay Audi approx £25 and only have to replace it again in 4 years, I have decided to buy this

Benefits:
Longer shelf life - upto 8 years
It can easily be rinsed off the tyre using water to allow full repair.
Easy to use. Connect pump to bottle, and then bottle hose to tyre, the product is pumped in as tyre inflates.
Hopefully will never need it, but worth having.
