Had my MCU replaced a month ago when it died — car was driveable but would only charge at about 280W net to battery, so too slowly to be practical. The usual rebooting didn't work, nor did pulling the main fuse under the phone guidance of the Ranger.
That’s odd. I didn’t realize the CID played an active role in charging. It holds the scheduling and charging amp data requests from the owner, but only the gateway should be needed in theory.
