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.

I know it's not the spark plugs. I've had the spark plug chirp before, and it came with misfires. Had all 6 coils, plugs and tubes replaced less than a year ago.

I've connected the car to a Porsche scanner and its so weird it no codes come up.

The majority of the sound is coming from the exhaust area, and I think it might be a leak in the exhaust system somewhere. That could cause a jumpy idle and the suctiony sound.

I will take it to a muffler shop to check for a leak..

Thanks!

Keep us posted I am always curious as to results.
Good luck with it.

There's a lot of great troubleshooting advice here. I believe you'll find the culprit if you follow the advice.

On another note... does that sound compare to this?
