All was going well with the 348, until a few days ago it decided to alarm one evening, shut off ok, not sure what triggered it. Alarmed a couple days later, now can't shut it up! The immobiliser part still works fine ( Cobra track 5,) I can start the car fine, just can't stop the siren. At present sitting in the garage with the battery disconnected. I feel the best way forward would maybe to have it all removed.
