Ok, my trophy has been into the garage to fix the charge once and stop. Confirmed by the garage, then some updates done, well a lot really. These are the modules updated (I did have an update to fix the DC charging issue on the EVCC previously): BMS, BCM, CCU, EVCC, IMCU. Tested Ok, further updates on FICM to R46 for the Bluetooth issue. Then updates to FDR and FUCM for the LKA.
Drove it back and put it on supermarket charger (thanks previous threat to test straight away), this time the car charged, stopped after a minute or so then started again, and over again, tried again on home charger and same issue. I'm guessing the tech looked at the charger and looked later still charging so fixed,.... but not fixed. Also the R46 was partially installed as the ACC changed by 1 mph each tap but the system stated still at R33 and the main screen still looked the same. Tech dude perplexed and tested further, stated that there had been more fault codes picked up by the garage test laptop in the time I have driven it about 40 miles so the consensus was it was buggered.
MG UK now contacted and awaiting a response from them. Garage good, I did have quite a few coffees there and everyone helpful so will see what we will see on what happens next.
