To close the loop on this I have fixed the rattle, turned out to be the cartridge rattling against the inside of the seat tube / stanchion. A few layers of tubeless tape so that it's a tight fit and problem solved.
I've also applied a heap of silicone grease to the shaft (nothing worse than a dry shaft) and lubed the shit out of the actuator foot valve jigger.
Will test ride on the weekend but seems 11Ty times better on the bench
