Hi, just 6 months into a 90 owner and just 1 nagging problem. If I forget to disable the alarm the horn and lights go off and correct themselves when I disable alarm no probs. But lately on turning engine off a siren goes off for no reason for 30 seconds and repeats over and over, I cannot stop it but can turn engine over, drive and lock and alarm the defender but the siren goes on and on for around 5 minutes. Has anybody any idea what I'm doing and what I can do about it. The siren is annoying and doesn't seem to serve a purpose. Cheers KJ
