The self-levelling system requires a base pressure to function. I believe the function is described in 32-501.
Typically the base pressure valve (integral to the levelling valve but not adjustable/influenced by the position of the lever) will weaken and you'll have insufficient pressure in the system. It will then sag and may even bounce/wallow, but it should be soft. A very hard ride is either too much pressure (lever is maladjusted and car rides too high) or spheres are shot (gas pressure has dissipated). Car should ride at correct height even with lever in "exhaust" position. Moving lever to fill will result in the car rising. Once risen, the car should stay at that height even with the lever in the "neutral" position. DO NOT ADJUST the position of the lever relative to the valve shaft. Only adjust the lever's connection to the sway bar. Spheres last five years at most, although they are rarely changed with such frequency. Your local Citroen service person may be able to recharge the spheres, but new ones aren't that expensive IIRC. You could quickly build a test rig with a bottle jack - plans widely available for Citroen sphere testers... HTH, D.
