Just home after being recovered (well, car picked up and will be delivered tomorrow, me home in a taxi). The strange thing is that I'd driven 150 miles this morning and it started okay in the afternoon when I went to drive back, and did 100 miles before I stopped to grab some dinner stuff on the way home. The message saying 'cannot restart, don't turn off' would have been helpful if it had flashed up before I'd stopped!

Anyway, I posted before the recovery had turned up but once he did there were about 100 codes flagged across a multitude of things (DSC, gearbox, ABS, fuel pump etc etc) which does make me think battery, but unfortunately he couldn't clear the codes to try restarting even with the booster pack on. The key bit to that seems to be that the car has got a code which doesn't allow it to be restarted regardless of what you do until it's cleared. We tried pulling the positive terminal and giving it fifteen minutes as a last resort but that didn't work either. Hopefully the battery is the cause...it certainly seems likely given it was registered April 2015 and it's still the original, and it's been sounding not perfect for a little while now when it's cold.
