What to about car alarm going off intermittently with nothing around the car? on 2009 Volkswagen Jetta TDI

Parked in carport as usual. Alarmed car as usual. Alarm went off for 30 sec. Unalarmed car and stood there looking at it. After 5 min car alarmed itself and then the alarm went off. Nobody touched it or the key. Thigh appended 4 times. I moved the car to the other side of the property and alarmed it. So far it has been quiet.

have you ever disconnected the battery and then reconnect it? if you do this,your alarm will sound again, You need to find the switch(button) and hold it down for 3 second then start it. have a try.
