Hi all,

I've discovered that when I open up the boot lid, the "door open" symbol on the dash doesn't work anymore and consquently the alarm re-arms itself with 30 seconds (the safety feature to combat false button presses).

The car is showing up no fault codes related to this, so i can only think its a short on a wire somewhere. (The fuses are all working and test ok).

Anyone know how to best go about checking this?

The switch should be in the lock mechanism, if it's like the other doors.

So maybe try cleaning it or squirting it with WD40.

The micro switches in the lock mechanisms have a tendancy to wear out, so you might just have to replace the lock if you can't get it working again.

Check to make sure that you don't have a broken earth wire either inside the boot lid or in the boot itself......
