Makes sense that batteries are flat after nearly 10 years.
But I don’t understand why PIWIS indicates Not Present AND gauge still indicates pressures for each wheel.
Path forward seems to be R&R 4 wheel txmitters and hope the system recognizes / learns them. Is there anything I can do to help ensure that the recognition / learning process occurs?
I haven't heard of anyone replacing the stems and still not working. I am sure there are some out there. At the very least it sounds you need to replace them. If it was me, I would buy 4 new stems, install them and get your car to recognize them. Sorry If I am not much help if you are DIY. …. So if I was in your shoes, I would buy new TPMSs, install them and go from there. You can get good prices from https://tpms247.com/.

I have read of multiple instances where people just "replace the txmiters", but additional adaptation is required.
On my 2009 997.2, the Huf Beru TPMS sensors sync within 1 mile. I have them on my spare wheels. No coding or intervention needed when swapping between wheel sets.
I bought a set of HufRDE011V21 from Tirerack in 2017 because they were direct fit and didn’t any programming. The car recognized them before I got to the end of the block.
If you’re willing to go with sensors that require programming, they seem to be cheaper and other people have reported success (e.g. I see the Huf UVS2000 mentioned a few times). Here’s a few threads to read:
Look, the TPM sensors in the wheels have batteries. They are rated for 5-7 years. You already admitted they are original close to 10 years old and the PIWIS is saying 0 months left. Since PIWIS is connected to the car it already confirms the RDK control box is working properly. Without working batteries in the wheel sensors there is ZERO data sent from the wheels to the antennas in the wheel wells, and ultimately back up to the RDK control box in near the brake master cylinder.
Stop over thinking this one. Your TPM batteries are dead. Buy new sensors and move on.

Great advice.. It's Occam's razor
I'm on my 3rd long term Porsche with TPMS, and find the batteries tend to last way longer than expected, but when they are overdue you get intermittent errors such as you are seeing.

Thanks for the feedback.
I asked because several years ago I bought replacement OEM sensors for an 07 Turbo and they needed additional adaptation.
I'm going to buy 4 of the HUF txmitters, have them installed, and see what happens.
I agree on all above. The sensors have non-replaceable batteries and lest 7-10 years. Once shot, new ones will fix you up and the car has no issues seeing them as long as they are selected for the right model. I'm glad to help you buy if you need the help.
Most of the issues you read about on this forum where people have to do some kind of programming (or think they need to) are just situations where they bought the wrong sensors.
On an ‘09, when you buy the right ones, your car will recognize them within a mile or so on your first drive.
Most of the confusion around TPMS on these cars comes from two issues:
1) Porsche changed sensors occasionally, sometimes there are two or three sensors in one generation of car.
2) Many of the vendor sites have confusing or sometimes just plain wrong application information. It’s easy to get steered to the wrong sensor.
I have an ‘09. I’ve ordered the wrong sensor before because the listing on a site was wrong. But at least in ‘09, once you get it right, the car doesn’t need any help picking them up.
Also, you don’t need to spend hundreds for these. I, and lots of people here, run discount aftermarket TPMS and have had no issues with them.
