Update
After several attempts yesterday and getting nowhere (as above), I tried again this afternoon and, lo and behold, it worked! All the data, graphs, dials, etc appeared on the tablet like magic.
It picked up a fault code for a blocked EGR. Took EGR off and it was pretty sooted up. Gave it a good clean, put it back and cleared the fault code. Unfortunately, although the car still runs fine, the engine check light came straight back on and Torque is still showing a fault code for a blocked EGR. So not quite sorted yet. Will give it another go next week-end when I will have more time.
