Was watching a walkthrough on the new S3 on the Audi channel the other week where they go through the features on the car. Towards the end the bloke was explaining how to lock and unlock the car with the key and explained that the key could tell you whether or not you have locked the car or not. I'm presuming this is when you are away from the car, can't find any info, how to do this and I didn't know this could be done! Anyone know? For info its repeated at 4:45pm this afternoon on 884 on Sky.
