The other day my wife and I were in our local supermarket car park. When we came back to the car I saw that the passenger door was wide open, and my first thought was that the car had been broken into. But upon checking it was simply that my wife had inadvertently left her door open and despite me pressing the remote control and the mirrors folded in and the indicators flashed once, there was no warning that the door was open. Is that normal? On my previous (non-Audi) cars it has not been possible to lock the car if a door was open. If it is normal behaviour on my A3, is there a setting (perhaps with VCDS?) so that a warning is given?
