You’re right I’m not using the Audi charger. I am using a 240V /12amp charge in a 6-15r that looks to be generating 2.3 kW per hour. I was going to try to plug in the Audi household socket with the Audi charger (and use a 6-15 adapter ) but I haven’t attempted that yet. Maybe the lights would be different but I would be surprised the charger makes the difference. I briefly tried the Audi charger in with the household socket in 110 V receptacle, but I didn’t take a look at the charging lights on the car.
