How can this be?

2008 Cayenne S w/PASM.
I've replaced two front air shocks TWICE with Arnott's in the last several months - the new shocks blew out the bellows after less than a couple hundred miles. Separate incidents, fortunately RockAuto replaced under warranty. Good thing my labor's so cheap... 🙄
Also replaced Level Control Module, Gateway, 2 front level control sensors, compressor and valve block.

I have PWIS III and (via Drive link checks) emptied and filled the shocks and accumulators, and (via Maintenance) calibrated the corner heights successfully. It's not throwing any Level Control DTC's ( a few others - TPMS, Headlight Control Unit, KESSY, left rear marker light - not too worried about these right now)

So I check the "Actual values input signals" and "Measured Pressure in XX air spring" is 0.0 in all 4 corners!

I can ignore it, but I'm afraid to drive it out of fear for blowing another air spring.

What am I missing here and I'm asking for help in figuring this out. Let me know if any additional info is needed.

Thanks

Phil
