PASM shocks going back from sitting?
I recently got my unicorn RS, but have noticed the rebound on the pasm is really harsh. Something doesnt seem right with the factory shocks on the car. The previous owner mentioned this also and seemed to think it was due to the car sitting so long as a collectable. It only had 7500 miles when the previous owner bought it, Is that possible? Just curious what your thoughts are before I go tearing apart the car trying to fix it.

I suppose it's possible, but not likely. I don't know what the electronic parts look like, I assume its a solenoid on the piston rod comp, that makes a restricted orifice. I think that would be unlikely to be stuck from sitting. Could it be that the OEM RS parts are just pretty stiff? My base car feels pretty comfortable in regular mode, but there isn't much redeemable in the "pasm on mode" unless there are hoosiers on the car... and then its not quite enough.

It looks like the fail safe is full stiff. You could try to deliberately put it in fail safe mode, and see if you notice any change. I believe you can also see the shock current if you have a PIWIS tool

I disconnected battery and nada. Might play with the plug and try again with the DSC controller. It’s really an odd situation. Never have had this issue on any of the 2 other 997.2’s

do a visual: make sure right shock part numbers, right spring part numbers, make sure no visual leaks, and check electrical function with the PIWIS. If all that checks out, its in your head :-)
I had a PASM shock fail a long time ago, PIWIS identified it.
