Registered User
I have a problem with my exhaust valves I think there stuck open as my car exhaust note doesn’t change from comfort to dynamic and is always loud has anyone had a problem with there valves and what was the fix been told it may be the pins or something in the exhaust also getting this fault code P14AC00 on OBDeleven makes a clicking sound
Form the exhaust when I unlock the car?

Any signs of corrosion on the pin head on the underside?
I had an issue with valves squeaking and had to have the entire exhaust replaced under warranty
