Happy to say they've found the problem (although I don't have the car back yet).
Despite Porsche NA's initial diagnosis of a "software problem" (couldn't be, or all of you would be seeing this), my guess was one of a few things:
The hose, unfortunately, is literally bundled in with the wiring harness that goes from the back of the car (which is where most of the air suspension stuff is) to the front, and is thoroughly tied down and wrapped (you need only look at one of the P-Tech "water leak harness repair" videos on YouTube to see what a nightmare it is). So, Kevin, the tech, ran a long piece of solder up the hose to locate the kink/problem, measured carefully how far up the harness it was, cut the wrap, found the kink there, fixed it, verified the fix, and then resealed, fastened and buttoned things up.
They're waiting for final confirmation from Porsche (who is monitoring Taycan repairs quite closely) and the car should be back tomorrow.
So there you go: if anyone else has a similar problem in the future, hopefully Google will find this...and hopefully Porsche is going to put an additional QA test off the line to verify full airflow through all suspension feeds before giving the car the thumbs-up.
Thanks to @PanameraFrank for helping out by checking his car's reactivity to the height selections: it was good to get confirmation that operation should be quick regardless of position.
Despite Porsche NA's initial diagnosis of a "software problem" (couldn't be, or all of you would be seeing this), my guess was one of a few things:
- A faulty position sensor, which was sending a bad (or electronically "bouncy") height value
- A blocked or constricted pneumatic hose
- A blocked or faulty distribution block for the pneumatic system
- A bad solenoid or valve
