where was the cord/switch you pulled?
Did it have a picture on or near it.
can you lock the car with the remote? Does the alarm keep going when locked with the remote.
you may have released the lid for the soft top stowage compartment,this has catches on both sides of the lid. Once one of these catches opens it disables the boot release because if you open the roof stowage lid and then were able to open the boot lid the two can collide causing body damage.
You should be able to push down on each side of the roof stowage lid from inside the car to latch the lid back in,I don't think you can do this from outside as you cannot get above the position of the latches,remember there is a latch on both sides of the car.
Thanks Sean that seems to be the problem have taken your advice and the boot has opened. Unfortunately once closed again will not reopen, have tried pushing the catches at either side (seat height on the left and right) backwards, forwards, upwards and downwards and the boot only opens occassionally and never reopens when closed unless I push the catches again and then not everytime. What am I doing wrong?
Unfortunatley I think you are going to have to remove the hard top to investigate further.
The catches or switches may not be secure enough and are moving or it may be that when you push on the lid the switches are activating but the catch is not closed so when you shut the boot lid the roof stowage lid moves again. From what you have said it certainly appears to be the roof stowage lid switches or catches.I know from experience that the stowage lid can be awkward to secure even when you are just using the soft top.
just a bit more information for you. In the car between the seats under the light there is a lockable stowage box inside this is another lock if you turn this it should release the boot lid mechanically.
