High pitch tapping noise

Trying to decide if this is a normal noise that I’ve never noticed until today, or if it’s something more concerning. It’s a high pitched tap that has a sort of rhythm to it. Doesn’t sound like any of the usual valve-train or injector noise I’m accustomed to. Starts around the 4 second mark, might have to turn your volume up or wear headphones to hear what I’m talking about (it’s echoing off my retaining wall).

 

Bump. Anyyyyyyone?

 

What did your dealer say?

 

Trying to avoid going there until I can narrow it down more. I know if I take it right now they’ll say they don’t hear anything.

 

I figured that if you could catch it on video it must be pretty noticeable.

could a leaf have gotten into your blower?

 

No it’s definitely in the engine bay. Problem is I can only hear it when I’m driving next to something with the window down.
