Hey guys!, got a slight problem with my factory fitted alarm on my a4 cab 2002. Every now and then a little after i've locked the car, the indicaor lamps start flashing but no sound of the alarm. I then have to unlock and lock it again, but it happens again sometimes. I'm pretty sure the car has not been touched or anything in order for this to happen. So, if one knows the reason, please let me know. Thanks!!!
