I've had my etron for 2 weeks, went out of town over the weekend - car was plugged in, assumed it was plugged in correctly but not sure as the Audi app is down (haven't been able to set it up yet) and I didn't go back out and check it. The charging light flashed yellow briefly, now it won't do anything. Car is dead, using charger that came with Audi - it has full power on the wall. I think it possible I didn't put the car in park, but not sure. I don't know what to do to rectify the issue. The Audi dealer is supposed to call me back. Does anybody have any experience? I'd love any insight.
