Viesel/DavidNJ, any of you experienecing minor shuttering when you turn off the ignition? Don't know if this a common phenomenon as I've never owned a diesel prior to this.

We pick up the car on 3 Sept. I don't recall anything unusual on turn off during the test drives.
P.S.
No ignition. Turn off engine.

Yeah, same here. Most noticeable when the engine is cold.
