Although this appears to be a case of the fob button being pressed accidentally, there certainly have been reports of some VAG cars winding the windows down for no apparent reason.
What gets me, at least on mine, is the auto re-lock function. Basically if you unlock the car but don't open any doors for about 30 seconds then it locks itself again, to guard against accidentally pressing the unlock button. Fair enough. The problem is that if you unlock it and use the fob to window the windows down, 30 seconds later it locks itself and then the slightest breeze will set off the motion sensors and the alarm goes off!
You can turn the motion sensors off when you lock it if you need to so why can't the car do this for you when it re-locks after winding the windows down? Smart-arse engineers missed a trick there.
