I just got a used Audi E-Tron 50 quattro recently and was loving the experience until it hit a snag with charging. The car's got a full Audi service history, so I didn't see this hiccup coming. Initially, charging at home with my Ohme E Pod and standard 3-pin plug was smooth, as was using a CCS Instavolt charger. However, things took a turn when I tried charging at my caravan using the 3-pin plug, it stopped unexpectedly and hasn't charged since. Audi's been zero help. Anyone else dealt with this? Got any tips?
