So I have been rattling my brain on this for a while and read the manual several times to no avail. When I get in the car and start it I cant leave it running on the drive without it shutting off the engine when I open the drivers door. If I want to defrost the car on the drive I have to sit in it and make sure the door doesn't get opened. I have looked through the mmi options etc and cant find anything on it to stop it from switching the engine off. It has stop start obviously but this is a bug bear that id like to overcome. Anyone know what im missing????
