My RS Q3 SB has a sports exhaust with 2 valves.
With the ignition on, both valves are closed, i.e. VCDS reads 10%.
When the engine is started in Efficiency, Comfort or Auto, both valves open, i.e. 90%.
In S-mode or Dynamic valve 1 closes (10%) and then you get a different exhaust sound.
There are no setting options for these valves in the MMI.
Module 1 - Engine has no longcode texts, so you won't find anything there either.

The question now is: when or under what circumstances does valve 2 go to 10% ??
