FYI Pajero owners with TPMS sensors.
These provided a spanner in the works so to speak.
As it turns out, the Pajero TPMS sensors are clip onto to the valve stem and cannot be attached to the Apex deflator and the special adaptor that they also sell won't work because it is a screw based design. It could be possible to not attach the sensors and live with a permanent warning light for the TPMS system warning. Disabling it in the computer apparently is also very had to do.
In the end, I decided not to do this and will continue to unscrew the valve to deflate. Also very fast and no additional cost.
If anyone has an alternative solution, I'd love to hear about it.
