Thanks Jonathan. I’ve just removed LH (original) as all the symptoms are of LH failure.

Luckily Carol Nash offered a recovery service - the car had to be put on skids, dragged onto a truck and recovered from Liverpool to Wiltshire, whereapon I got the spare set of keys and drove the car off the truck and back up North.

I did change it for a new one as preventive maintenance a few years ago but perhaps it’s failed. Can’t test it properly till home and now waiting to be recovered, but if I’ve missed anything obvious please say!
