Sorted the creak today.
Don't know how long it will last, but as I suspected the problem especially on the carbon models is that the head set bearings actually have a small bit of play between the bearing and the frame, and this slight gap causes the creak.
I simply put one layer of ptfe tape around the circumference of both the top and bottom bearing and then reinserted them.
This small amount of tape took up the slack and hey presto no more creak ?
This is a worry though, because where there's movement wear will occur, and I can see a time where the bearings become loose in the frame and then the forks will move too and throw rendering the frame useless ☹
