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”.
I think that you can feel my disgust with Audi’s lack of customer care.
