Hello masive39

The no faults found is a good indicator of an electrical power fault. Along with spurious error messages displayed all indicate an electrical problem with the engine ECU and it's sensors.

It could be the engine ECU , one of its many sensors/actuators or a problem with the loom (short circuit)

This is not going to be easy to diagnose. One thing that may help is to try to look for a pattern. Does it happen in acceleration, braking, cruising after a long run? Any pattern at all?

I don't think there will be a cheap fix because of the time required to diagnose the whole ecu system :(
