Hi,
Could,nt hear it? does your make an audible bleep when arming/disarming the alarm then? As i thought they meant to be silent.

yes mine beeps its the unit inside the n/s wheel arch it stopped beeping ( through old age i think ) . saw the remedy on the forum and replaced it and it has been fine until now .
