Hi all I hope you can help I have just brought a six month old Vectra 2.2 SRi Within 2 weeks of driving it, the engine suddenly would seem to cut-out and the car lose power-all lights would go out, I'd lose power-steering, no acceleration-dead. I could then turn the ignition off then on and the car would run normally The garage said that the computer error said that it was looking for a different key code and they suggested trying my spare key. The problem remained and the car was still cutting out The garage said that the computer said that the car was effectively de-mobilising itself and the car needs to go in for a 'mod' to the wiring loom. They wouldn't let me talk to the mechanic and wouldn't elaborate on the fault. It was in for 2 days getting the mod, This was a week ago. Today the car effectively 'demobilised itself' again today. So whatever they did has not resolved the problem. I'm taking it in tomorrow but wondered if any one else has had this fault on the new model SRi Vectra. If so does anyone know what might be the cause. TIA Regards Sheri
