I've had this problem on and off (mostly on) for a while now.
Whenever i unlock my '04 320Ci, all 4 windows and the sunroof start opening. I can stop it by quickly opening the drivers door, then pressing the lock button on the remote which stops it, then when i get into the car, they all close again. But if anyone else unlocks the car (or i forget) the whole lot opens, which is a real pain when its raining.
I came across a thread somewhere which said they sometimes need resetting, and you have to go through a series of steps that involves disconnecting the battery, and resetting the ECU to reset the window position sensors, but i can't find the article now.
Does anyone know what might be causing this, or how to reset it. Its driving me nuts!
TIA for any help.
