Not able to test it because my A3 isn't delivered yet, but according to both Ross-Tech and ODBeleven they aren't yet able to do anything on 2020+ models...
Due to extra protection of the modules (SFD).
Also in case of VCDS (vagcom) you will need a HEX-V2 or HEX-Net dongle, HEX-CAN would not work, according to their website.
Grtz,
