Hello! Need help asap. We just got our Tesla #1316 today, plugged it in Universal Mobile NEMA 14 50, got the flashing blue, a flashing red light and then "line sync error" message. Unplugged everything, plugged it in again, and got the same sequence. Car charges normally (albeit slowly!) on the 110. We called Tesla, and they say its a problem with the line. We called the electrician and he says line is fine, it's a problem with the car. Any advice?
