Welcome to the "Fest there, "Hapye" (sorry, little play on your chosen handle of "Madde")!
Well, I just posted in Vern's thread how great my '05 545i has been so you probably don't want to hear that. I haven't had any major issue or little niggling things other than a couple NAV hiccups now and then that haven't been anything to worry about.
Sometimes my radio will stay on for a few seconds after shutting the car down but it doesn't happen very much. So, perhaps it is normal.
