On scanning the error code is :PC058A Battery monitor Module Performance. The fault is cleared but as soon as driving starts it reappears.
Do you

Hello,

9 times out of 10 it will be the battery pack which has a bad cell the monitor has picked up on. Here are the engine and hybrid driver wiring diagrams so you can see how the system works and which fuses to test if needed. Also I have included how to change out he battery. I have seen people online open the battery pack up and find the dead cell but this can be dangerous. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
