I looked at related threads but no real help.
My 2007 with Bilstein PSS9s recently developed PASM failure after battery went dead. Took to dealer, they found open circuit (short) at LF damper wire. I sent damper to Bilstein, where they tested and found that damper was operating entirely within specs, and worked as intended on their PASM simulator. Damper back in, but can't get rid of PASM failure. Before going back to dealer, wondering if anyone has had similar problem, and any remedy. BTW, no ECU mod, or anything else. Dampers have been on car for almost 10 years without issue. Very happy with them.

Mine did the same after disconnecting the battery to wire a battery tender in. It cleared itself after driving a few minutes.

Clean all the contact points and check the wiring that goes into the shock. In particular on 997.1 those wires would kink or strectch or bind or etc. and they are very fagile. I had that problem with two of my shocks at different times.

I am not that lucky. PASM failure seems to be permanent, at least until I find the problem. As for cleaning the contact points, I tried with a needle. Not like you can just scuff them up with some emery cloth. Too tiny. Next, I'll try to check current at the connector if I can get a proper tool. If all else fails, back to dealer. Can't really drive the car around here in firm mode, just too jarring. And yeah, I know, if it lasts for more than 4 hours, consult a doctor.
