Here is that letter "ex-expats" was referring to...I called the number below and they said they have 4 etron experts in America who can help you with anything you need regarding the vehicle. Just wish Audi had one "genius" at each dealership where I can take the car for any issues.
Audi e-tron High Power Charging
Dear Audi Customer,
The 2019 Audi e-tron is capable of charging speeds of up to 150 kW at many public DC fast charging sites. Achieving such charging speeds requires both power transfer and communication between the vehicle and the charging station.
In a limited number of circumstances occurring only with DC fast charging, there may be a lapse in communication between the vehicle and the charger that causes the charger handle to remain locked in the vehicle after charging is complete.
Should this issue occur while charging your Audi e-tron, the following steps may be taken to release the charger handle:
1. Ensure that the charging station has stopped charging and that» the vehicle is unlocked, then press the handle release button on the vehicle (the same button that is used to open the vehicle’s charge port door). See page 108 of the Audi e-tron Owner’s Manual.
2. Wait 5 minutes after charging completes to determine if the vehicle clears the fault and automatically releases the charger handle.
3. Verify that the vehicle’s auxiliary climate control is turned off. See page 84 of the Audi e-tron Owner’s Manual.
Should these steps not release the charger handle, the Audi Customer Experience Center is available at 1-844-573-8766 to provide assistance. After evaluation, the Audi Customer Experience Center may recommend
releasing the charger handle by manually pulling the release tab that is located under the vehicle’s hood (page 1 11 of the Audi e-tron Owner's Manual).
Audi is currently resolving this charging issue and a software update will be available by the end of 2019 to correct the issue in all Audi e-trons. Affected customers will be notified when the updated software is available.
We expect the occurrence of this issue to be isolated, but we apologize in advance for any inconvenience that you may experience. Should you require assistance with this—or any—charging issue, our skilled customer support team is available to help.
