Hi, On two occasions now have I come back to my A4 Avant Sline 56 plate, to find all of the 4 windows to be open by about 2 inches (and one time it had raied quite a lot letting water in). It'ls like some "airing mode" had been activiated or something. On both occasions I left the car thinking it was all sealed up although I could have easily missed these windows being open. I just wondered is there some button combination that can be pressed to acheive that, or have I on more then one occasions just not closed all the windows properly and happen to have left them all open by about the same 2 inches? Any ideas?
