Coolant leak & puddle under rear carpet, but replaced tank less than 4 months ago.

Well, I guess I'll go out there and try and find the leak!

In your first picture the first hose on the left is showing a powdery residue under and around the hose clamp.
Could be a leak or a leak from the past.
Pressure testing the system is your best starting place to correct the issue.

Reread the thread.
The hose with the powdery looking residue I pointed to is in the second picture not the first.
Sorry

1. loose hose clamp
2. bad hose
3. bad cap (even though you said it's "new' might still not be the latest version)
4. non-OEM tank (lots of crappy replacement tanks for less money out there but in the long run it's wiser to pay the price and get the "real deal" from Porsche
