You're absolutely right about the PRT
No further coolant loss, so for the moment I remain slightly stumped and a little anxious. I need to plan another road trip and regain my lost confidence in the car!
Less getting time than expected this weekend, but I think I've finally cracked the annoying misfire!
After the fun over Salusbury Plain, loss of under tray and subsequent spectacular misfire, I took the HT cover off today to change the HT leads for nice new Magnecore ones (I've had brilliant experience these over the years).
This is what I found:

There is mud around the coil pack and down the #1 spark plug hole!!!
The new HT leads certainly helped the cold running enormously. But when warm, one of the coil packs started misbehaving again. The error codes and live data feed provided the necessary confirmation that it was the pack that had been bathed in mud that was misbehaving (it was playing up before, so it wasn't just Wiltshire mud causing problems!)

A fresh coil pack was restored sweet running to this Hippo.
Still to sort:
1. OSF drop link
2. Both front lower wishbones
3. OSF ABS sensor +/- a yaw sensor (the latter may just need recalibration G?)
4. VCU support bearings
Get this lot done and I've got a nicely sorted Hippo!
