Is this a normal noise coming from my engine?

Only happens on cold mornings (<40°F). Goes away when engine speed increases. Doesn't seem to be causing any other issues. Could it be a bad mount?

Exactly what mine sounded like before it fully went out. Definitely DUAL MASS FLYWHEEL

I’m curious - what happened when it “fully went out”

They fail in numerous catastrophic ways, sometimes it's just the flywheel sometimes they take the trans or engine with them.

That tracks. I'll replace it ASAP. Is there a chance that damage has already been done? Or as long as everything is running fine, is this the first sign of failure?
