Goes off for no reason
I had a similar problem. The Antitheft reacts to voltage changes and views fluctuation as a theft attempt. My Lincoln did the same thing when it was 3 weeks old. I even sat in the Parking lot one night to see if someone was messing with my car. Turns out the battery was shortening out.

YOU WILL HAVE TO PULL ALL THE PLUGS AT THE UNIT ITSELF, THAT WILL CURE YOUR PROBLEM.

Not a solution, but details about the same problem with my car: I have a 99 Lincoln Continental and have noticed correlations between certain conditions and the frequency of the car alarm going off.
When it is hotter outside, the alarm goes off more frequently than when it is colder.
The more of a slant the car is parked on, the more often the alarm goes off. My boyfriend's driveway is on an incline and any time I park my car there, the alarm will go off every 30 seconds. If I move the car to the level street, it doesn't go off at all. This has been noticed on other slanted places I've attempted to park as well.

the factory fit alarm is not voltage sensing .The best advice is to go to VW garage and get them to read the alarm causes,(they can check the last 4).this will give you a good idea where the fault lies.ie door lock mechanism,interior monitor etc..You cannot start looking for problem until you know alarm cause..

there is a hood switch located at front passenger side under hood. check to make sure the plunger at hood is pushing the switch completely down. sometimes there may be just enough clearance that a strong wind will set the alarm off.

If you can turn off the internal ultrasonic sensors (many cars allow this so that pets can be left in a car) it may solve the problem. If you can't winding a window down a little sometimes will help
