211 estate boot auto close button not responding

[DavidL]

Of late the boot doesn't want to close from the red button. The close system works fine, soft close etc.
I'm sure it's just the button wiring as if I push gently in one place on the the button surround it lights up and works.
So first question, does the button itself just pop out with a suitable tool?
Is there an estate boot lid breakdown somewhere?
Thanks
