Customer Question

Hi there, the motion sensor on my 3 series ( 318) tourer keeps going off, for no reason. I have tried to deactivate it by pressing the central key button twice, and by arming it with a back door open then closing it, and finally by just locking it with the key in the door, which seems to , but means my alarm isn't on, which isn't ideal. Do you know what ,might be causing it and what I can do to resolve it?
