I had a issue with my pse not switching and the right hand silencer sounded clanky so I set about investigating.
The right hand flap actuator was working fine but was pulling the flap closed no matter how the dash switch was set, the left hand actuator was seized and the vacuum pipe was hanging loose, I managed to lubricate the left actuator and free it so refitted the vacuum pipe but they still refused to work so I then tested the Pierburg vacuum control valve it was passing through the vacuum whether powered or not so replaced the valve and the pse is now working.
BUT, when the the car is cold and the pse set to quiet the right silencer is still a bit clanky but fine in loud mode, so in the near future I will need to remove the silencers to possibly repair the corroding seams and will look closer at the state of the them.
