Another issue that I just realised may fail me the NCT - my boot button recently stopped working.

This is the one on the outside of the boot above registration plate.

These all work:

Key remote button opens it
Internal button (beside bonnet release) opens it
Physically turning key opens it

I checked the lock cyclinder position, that doesn't seem to be the problem as boot button doesn't work whether lock is in vertical or horizontal.

Am I right in thinking that if the other methods work, it's not the wiring loom?

Is this an NCT fail issue?
