hi i have looked and looked on the internet regarding siren issues....I found that my original siren was knackered with the old battery leaking failure so i sourced a brand new alarm siren. I have now fit this and tested through vag-com and no faults coming up now but no sound coming from the new siren when in test mode or if i manually test it by arming the car with the key fob and moving inside the car. The indicators flash repeatedly but no siren sound?? I have also set the car to beep on lock with vagcom using a few alternative codes but that doesn't work either. Any help would be greatly appreciated!
