I wouldn't even know where to begin with this!!

Agreed. I have redone the connection to the diff sensor in the past and have checked it recently using an Arduino while driving the car so I know that it is fine.
The symptom of me smacking the dashboard which causes it to come back to life suggets that it is something in the cluster / board itself regarding the signal - but it is hard to isolate when the problem is intermittent- I've tried my best to check as many of the blue plastic traces as possible for continuity and all seem fine!

Losing your mind? Welcome to full-fledged Volvo ownership!
Joking aside, where did you insert the Arduino i the circuit? Was it across S (signal) and earth (0V) on the speedo connectors?
Also try cleaning all the copper strips on the back of the cluster and the "fingers" in the multiplugs that contact them. Also use a thin screwdriver or similar behind the curve of the contacts in the plugs to "stretch" the curve out to increase the tension on the contacts and hence the pressure of the plug contacts against the strips on the PCB which usually solves a lot of problems.
