    Hi this has been annoying me for quite a while now and read many threads on here relating to the problem but nothing has pointed me to the answer. I have removed my old leaky alarm and fit a brand new one in its place. Also i have fit a brand new car battery. When you lock the car and deliberately set the alarm off only the indicators flash there is no sound at all from the alarm siren?? These are the fault codes below that I have just copied from a recent VAG-Com fault scan. I hope someone can help, many thanks
