Hi Cent.
Cheers for your reply. I spoke to Audi again a few days ago. They suggested, left foot hard on the foot brake, right foot hard on the accelerator. Then press and hold the Stop/Start button for a second. As soon as the engine starts take your foot off the accelerator. It will then fast idle and allow you to set the windscreen defrost to warm the screen and the car. By the way, you have to unplug the charge lead as the car won't let you start it while it is connected. Martin.
