Help needed please. I have bought a 53 plate C-Max 1.8 Zetec and absolutely love the car. It night and drive like new and has only done just over 50,000 miles. The only problem I have is that the alarm decides to go off anywhere between 7.30 at 5 in the morning. The battery is fully charged and is not faulty. As far as I am aware there is no internal sensors fitted in the interior light cluster. I have checked the display for any codes but it shows none at all. I have noticed on another forum that it may be the bonnet switch and to disconnect the switch and place a wire link between the wires to simulate the switch which I am trying now. Any help would be appreciated. Can the alarm be completely turned off or would that mean that the immobiliser wouldn't work either.
