I can also confirm that version 3606 also does not work. Both processes complete without error and a power cycle and reconnect verified the setting change had been applied. Showed RS for App and 5 for adaptation, but still no actual function on the taillights. 2022 MY S3 built 7/2021. Waiting for support to be available to get some info from ODB staff. I do know previous models of Audi’s I have had came with different ECU manufacturers. Two previous gen S3’s in my family built 6 months apart had different ECU makers. One was Bosch the other was Delphi. Continental is also another manufacturer. It’s possible this is the cause. APR runs into this with their engine tuning software also. Available for one ECU make but not the other.
