Thanks for your reply. I had my independent garage scan the code and it pointed to general fault and they couldn’t tell me whether it was the module, the overhead sensor or they said also the module in the rear boot, which I didn’t know also controlled the alarm?? Is this true?
I have an issue with my 2007’s internal ultrasonic sensor. When I lock the car the door LED flashes and then stays on as if I’ve pressed it twice when I haven’t, and the car has been broken into twice and the alarm has gone off zero times annoyingly!! i have tested the sensor at roof level and it’s getting 12v and doesn’t look wet or anything. I’ve even swapped it for another unit which made zero difference. It’s as if it’s been disabled in the ECU or via the door pillar button which in any case isn’t there at all on my model. The computer menu says it’s checked so it ought to work
