Did you check the oil level? Are you sure that's oil on the ground? Kinda looks like it's water and it's in the area where the a/c compressor drips condensation which is perfectly normal. I agree the engine doesn't sound great, I don't like that hum (the ticking is the injectors and is normal), but I'm not sure you have an oil leak. If you do, find it and you'll likely solve your problem.
Hard to say from the internet but at 180k miles i think i saw in the vid, could be bad. Or maybe not. The sounds didnt jump out at me in the video but it was taken on cell phone which isnt as good as listening in person. I didnt see smoke from the exhaust.
Sound like it cranked a bit slower than mine does. The fluid on the ground is far forward, more likely coming from the front of the engine or radiator. I also didnt see an underbody shield, did you take it off or is it missing?
You mentioned checking the oil and it was ok. Did you check coolant or did the fluid smell sweet?
PDCC lines age and burst with minimal warning, and it will leak in that area, and cause a Chassis System fault. The loss of fluid will destroy the very expensive tandem pump if you run with the system empty. Get it fixed without driving any more, or the fix will require parts costs in the several thousands, versus several hundreds of dollars.
And replace the rear lines while you are at it, as those will soon fail and are only about $80USD each. And since you need to drain, refill and calibrate the system anyway, may as well do it once.

Hey guys, here's the update. I took it to the local shop my friend recommended and the mechanic and shop owner checked it out. They looked under the car and saw that there was oil dripping out of the nut for the oil pan and that it was making its way to the front drive side where it would drip down. It's still a relatively small leak, so that explains why the oil was still at maximum and not low.
He said when I take it in for an oil change in 6 weeks, he'll swap out the nut and it'll fix the problem.
As for the Chassis System Warning he said it was just the housing that was old and warn out, and there was no way he could reset or get rid of the warning code. He's a Porsche owner and enthusiast himself and seems both knowledge and trustworthy so I'm going to take his word. He only charged me 500uah which is $17 for the diagnosis.
I drove home using the different suspension modes, lifting it all the way up, dropping it down, comfort, sport, etc, and it seems to drive great. Biggest annoyance was only being able to fill up 10liters of gas (2.6 gallons) as it's still restricted in Kyiv. But overall, I'm thrilled it's not a $1,000+ problem.
That drip on the drain plug doesn't look like it could produce large spots of oil like in your photos in multiple locations.
Does your Cayenne have PDCC? If your air suspension and PASM toggles are silver, it does - if they're black, it doesn't.
if you have PDCC, the PDCC system is completely separate from the air suspension system - one is hydraulic and the other pneumatic - so the air suspension could lift and lower just fine while the PDCC system is bone dry. If the air suspension is working as you say and you still have a Chassis System Error message, then it's likely the PDCC.
Remove the beauty covers on the driver's side of the engine compartment and find the PDCC.reservoir - it looks just like the power steering reservoir next to it but is the one you can't see with the covers in place as there's no access door for it. Check the fluid level in that reservoir. If it's empty, with the drives you've now done, you've likely damaged the tandem pump used for it and the power steering
Also, what did the mechanic say about the timing chain?

How bad is this…Engine Problem?
