This has happened maybe 3 or 4 times in the last 2-3 months, however after doing an airport drop off this morning it flashed up again, this time telling me of a drivetrain and transmission fault, along with no power steering and no internal electrics. It kept failing persistently over and over again, after the 5th or 6th time it stopped for around 60s before cutting the entire car power. The gearbox started whining as I came to a stop although I believe this may have been my ghost immobiliser locking the gearbox.

I’m now kind of afraid to drive the car as it’s super random as to when it does it, but I lost power steering on a sharp bend and wouldn’t like to experience it again.

There’s zero faults logged, nothing on the dash so it would seem to me like an electrical fault. Could I be right in thinking a weak battery might pose this issue? I did have a battery discharge warning yesterday as I had been working on the car with the ignition on. The only thing in common to trigger the issue is I have always been coasting
a low battery can cause all sorts of issues. check the life of your battery and start there. I wouldn't think it would cause the problems you're experiencing but who knows.
