Strange mechanical sound: exhaust valves?

[kratty]

As I've mentioned in other threads, I am one of those experiencing frequent but random exhaust valve malfunctions. Today was one of those days where the valves acted up immediately this morning.

However, it did something new. When I shut off the car in my parking garage, I immediately heard what you can hear in the video clip below. The video quality isn't great, but I was holding my phone behind driver's side rear tire and underneath the exhaust tip.

The sound continued until I cycled the ignition into "on" without starting the engine. Otherwise, I'm not sure if or when it would have stopped on its own.

Thoughts?

That aint right take it to ford. When in sport mode and i shut the car off i hear that exact sound everytime which i believe is the valves closing to normal mode, but it only makes that sound once, not multiple times.

Servo motor on exhaust valve cycling. To the dealer.

Thanks. What I suspected. It was really going crazy. Guess it couldn't get back to its home position?

That's strange. Maybe try unplugging the connectors and the battery to allow it all to reset. Probably the sensor not knowing the valves position.

If that doesn't work then I would go take it to the dealer.
