I'm having a problem with my MG4 51 excite (Australian) where it sometimes refuses to start. I unlock, get in, dashboard lights up with what seems to be every possible warning. It doesn't display a battery SoC (just
The first couple times this happened I called roadside assist and each time, by the time they arrived, I'd go back to the car with them, unlock it, and it would start no problem, which was very frustrating!

If I get out/lock and repeat, it just gives all the same errors. When I unlock the car I don't hear the clicking/knocking noises that you normally hear.The first couple times this happened I called roadside assist and each time, by the time they arrived, I'd go back to the car with them, unlock it, and it would start no problem, which was very frustrating!
