Hi all,

AbOut two weeks ago my i3 stopped fast charging. I tried 10 different chargers on 3 vendors , all confirmed working. Received some variation of error msg regarding “communication error.” Took it to dealer, ran diagnostics which came up clean and connected to dealer fast charger and it worked no issue at all. Immediately went to EVgo station, tried three chargers (one of which had just fully charged another i3) and no go. Dealer just shrugged and said the car has no problem. What do I do?
What year? Had it had any dealer installed -software updates?
