I found a new feature on my B6 this morning

[danski]

Got in the car and started it - then cleared off all the frost from the side windows, why cant we have heated side windows too?
Anyhoo, everythings getting nice and toastie (heated seats) so I set off and as I pick up speed the seatbelt warning went off. Immediately thought my seatbelt sensor was faulty, so undid it, then fastened again. Nope chime still going off, then realised, my bag with laptop in was on the passenger seat, pushed it on the floor and chime stopped.
Pushed my hand where the bag had been and it went off again.

I didnt know there was a sensor in the passenger seat - wonder if they are in the back too - anyone know?
I know its not such a big deal, I was just pleasantly surprised.
