Over Xmas tried starting my car , dead battery tried to jump it and alarm went nuts and couldn't shut it off
Been reading the sigma don't like dead battery and has a habit of going in safe mode
Took battery off been charging it daily for 5 days , nipped home from work and plugged it in , alarm going non stop for about 5 mins , rang a mate said hold the fob button and after a minute it unlocked
Jumped in and eventually started
Was looking at wiring diagrams to cut it out but panic over !!
