was told that if you press and hold down the "open" button, this is what it will do: open the doors and then the windows part way.

My E46 had this same feature. If I held down the unlock button on the key, it would role down the front windows, and open the little back "wing" windows to cool down the interior of the car.

Of course, I had to be so close to the car that by the time it got done opening the windows I was opening the door to get in, so it wasn't something that I used very often.
