I have a 2000 a4 quattro and for the last couple weeks my stock alarm will go off for no reason. This happens a couple times a day and is really getting annoying. Is there a sensor going out or something. Other than leaving the car unlocked all the time i dont know what to do. Anyone have this happen before.

 

Do you have VCDS or access to it? If you run a full scan it'll say what's tripping it.
