Nice that you got an expensive new charge port but clearly your car didn't need it. Sorry you've had to make so many trips to the dealer. The error code sounds to me like a bad connection or ground wire somewhere in your car. Maybe take a very close look at all of the electrical connections related to the on board charger? Do you see any connectors that look damaged or loose or see any ground (brown in color) wires that are not secure?

I would continue to complain to the regional VW manager. Does the dealer that serviced your car sell ID.4s? If not, maybe you need to take it to a dealer that does as I would hope an ID.4 dealer has technicians who are better trained than those at pure ICE sellers.

I don't see any visible issues. They sell ID4's, but the service rep who was overseeing the repair told me that they don't really know how to service EV's yet and that it will probably be years before they are trained. Apparently they consult with VW headquarters and headquarters tells them what to do next. It sounds to me like the onboard charger needs to be replaced. I am asking them if they can give me a replacement vehicle.

Ok. I wonder if it is a bad on board charger, bad communication cable or bad CPU? This will certainly require a technician with EV expertise to diagnose.

That sounds correct. I assumed they were going to replace the onboard charger initially, but the just did the cables.

And is the repeated charging requests problem gone?
