As I understand it, that functionality went away when the 3G cell network was turned off because Audi didn’t give the e-tron a path to upgrade the cellular modem, so those cars lost all their mobile data connections. (My a3 e-tron app quit working altogether, so maybe they turned that off at the back end, too.)
That capability is gone. A/Q series 4&5 received upgrades, but these upgrades were never offered for the 3 series at all. I investigated to determine if it would be worth paying to have the same upgrades installed in our 2017 A3 Sportback e-tron, but was told to forget it, because it would involve extensive rewiring, parts removal and replacement, and the chips in it were not software enabled for the A3 e-tron at all. I was also told that the A3 Connect capabilities came for “free” in our Audi, so we would not get an update, since we didn’t pay anything for it anyway. Then I was told by Audi USA to just “buy a new Audi”.
We have a Siemens 32amp EVSE which we use to charge our A3 e-tron. It is always charged to the full amount allowed by Audi. There are no settings in our Audi allowing us to set the charging at any percentage, like is available in our Tesla. In our Audi, it is just “charge”. I have discovered that it only charges to ~6.2 kWh maximum on our 8.8 kWh battery pack (this was a few years ago), but that is only an estimate based on articles I have read. There is no way to determine that in any of our A3 Sportback e-tron’s software. It might have been available before Audi Connect disappeared, but nothing now. We have multiple apps for our Tesla Model 3 which give us that info and options to set the charging on level 2, but NOT on our Audi.
