    Please help, my dash warning light shows that the boot is still open when it is closed. The indicators do not flash when central locking the car, does any one have the answer please?

    I see a lot of cars with an intermittant fault on the boot release. Most people don't see any problems.

    However, I suspect that the wiring loom has been damaged where it flexes between the car and boot lid. Quite a common fault. The wire which signals the boot is open has shorted out. This in turn lights the dash mimic and prevents the alarm from arming (flashes indicators on arming)

    Well yes, your instance is a problematic fault. Most people do not see any faults. However the fault probably lies in the loom between the body and hinge of the boot. You need to locate the loom where it flexes, strip it down (remove loom lacing) and find the short circuit. You will find damaged wire insulation.

    I would say this is more to do with the built in micro switch in the actuator which has become faulty.

    Thanks for your reply, I presume the mirco switch is built in to the actual boot catch? If that is the case the catch was replaced some time ago but did not cure the fault.

    Incidentally I do see the problem every time I drive the car as the dash warning lights up like a Xmas tree as well as the niggling thought that the car may not be alarmed correctly.
