Does anyone know if dealers have any diagnostic kit that simulates an AC chargepoint they can plug into to the car to check whether it’s communicating as expected to initiate, maintain and terminate a charging session?
Was reading up about PWM comms protocol and am aware the car needs to respond by switching resistors in and out to manage the signal voltage with the chargepoint. Wondering if it’s failing to do that or there’s an earthing issue or something else.
I think my dealer is just removing and reinstalling software without understanding how the car is behaving. Stuck in limbo whilst they await instructions from MG on what to try next. I get the impression they are just using a device that checks the software and says either “this is fine”, “this needs updating” or “this is messed up - call MG” so are flying blind. Hard to tell when you can’t talk to the technician and im not convinced how well informed the front desk staff are on EVs
