Hi
Thanks for all the replies, very much appreciated. My car is now, once again, with Audi, and will be for a while, I have been given yet another courtesy car. My Audi yet again popped up with the start/stop whilst I was driving at 60mph, and had to brake to slow down briefly, it was not a happy moment!
I have had a lot of Audi cars over the years, and I have never had an issue with any of them, barring the one I have now, and this includes all the courtesy cars that I am driving at the moment.
