If you can find someone with a VAG COM (scanning tol) they can run a scan and find out what is triggering the alarm. Are any of your windows (or sunroof) cracked open? If so, there are motion sensors at the top of the B-pillars, and even a slight breeze can set those off. Otherwise, it might be a faulty/loose hood sensor. Again, VAG COM is your friend. Do a search for the VAG COM locator

It's probably the interior sensors. There is a switch on the driver side that looks like a tower with signals coming out of it. You have to hit that switch when you get out to turn the sensors off. It's right by the door jam. If you have the sun roof cracked or windows cracked, the alarm will sound if this button is not hit when you get out of the car.
