Unfortunately for me, it has not just been the Instavolt chargers where I have encountered this issue. I have tried charging at; FastNed, MER, Osprey and Shell Recharge and all have cut out from anywhere between 30 seconds to 2 minutes. Over Christmas I could not get a single charge from the DC network. AC is generally okay and granny charge works with no issue. My car has been to the dealer twice within 6 months of owing the car and is going back again in next week. Very frustrating and also upsetting as I really wanted this car, but it has not turned out the way I expected. Will see if MG they fix this time.
