Exhaust flap 2 blocked (C43 2017)




Exhaust Flap 2 Has A Malfunction. The Actuator Is Blocked.
Is anyone deal with that and what was the actual issue the spring inside the actuator or the actuator itself?
Mine work flaps seemed to work correct whenever i press the button as soon i drive for 5min after the cold start, so not sure what actually is the issue

When engaging the 2nd ignition position (foot off brake, so no start), you can clearly hear the exhaust valves actuate. About 5 seconds after turning the ignition off, there's also another actuation noise (presumably going to their at-rest position).
I did start the car and operate the exhaust-valve button and could not hear any actuation but I didn't let the car run more than about 20 sec as the garage door was closed.
