Owned my 550i for a year now and love it. I have been leaving the windows and sunroof cracked with all the heat lately and noticed something interesting happening.I When I am walking towards my car the windows and sunroof will all auto roll-up and close without touching the key fob. This only happens as I walk towards the car after it has sat a decent amount of time.

I do not have any coding done to my knowledge and the car is a bone stock CPO.

Is this normal or what is going on here? I tried to hold down the lock button on the key fob to see if the windows would roll up but it just sets the alarm off.

Thanks!

 

Happens to me sometimes too, don't know what causes it tho.
