On mine they are open when engine switched off. You can see them open if you look into the pipes. Then also on idle in dynamic. Once car moves they close.
Plugs are tricky to unplug and need small hands
I unplugged the connectors to my RS4 to keep valves open all the time (ie doing what the cete controller could do) and it made hardly any difference to the sound of the exhaust
Won't be ordering a controller now.
Quick update - I tried to simulate what the Cete valve controller would do (eg open flaps all the time in Dynamic mode) by unpugging the valves once open.

Hi guys I'm trying to work out when the flaps are open/closed. In dynamic I can see they are open on startup . But then do they close on moving until a given Rpm when they reopen? I've seen a kit to blank off the plugs to keep the valves open all the time £40 or so. Would this make low revs louder?
I've got factory sport exhaust and it's pretty quiet.
I'd hate to think what non sport version must be like
I'm tempted to cut out the mid silencers and have straight pipes welded in?
