The Audi e-tron charging port is located on the driver’s side front fender, just under the e-tron logo. After you’ve parked, powered down, and set the parking brake, you charge by pushing the button to the right of the e-tron logo and plugging in the e-tron charging cable.
The light glows white when communicating with the charger station and pulses green when charging. You’ll see a similar indicator pulse in the instrument cluster, which shows how much charge you have, how many miles you can go, and how long charging will take.
