Does anyone know what this noise could be?

Something else to add, I had the water pump and thermo replaced before.. I dont think that would be the cause.

The car has a jumpy idle currently. And the sound doesn't seem to be coming from the belt area. Seems more like below the car/exhaust area a si showed in the video.

When I have some time this weekend I will try to work on the car and try to run without the belt..

Another thing that is easy to check is your spark plugs.
you could have a loose one so check those out.
Just make sure they are not loose don't "over tighten" them.
I am starting to lean toward an exhaust issue.
a leak or a clogged damaged cat. converter.
You could take it to a muffler shop have them put it on their hoist and do an exhaust system inspection. If it is leaking they should be able to tell you.

Another possibility is the engine bay fan it can be triggered (run) with an OBDII scanner that has a Porsche program. like a Durametric scanner.
