i want to know how to test the citroen suspension system on sphere suspension system(hydractive),that can use or not.
Sounds like the release valves on the pump motor are stuck, or the module that controls the air suspension isn't good anymore.
it could have a top sensor close to the rear axle. in case you hear the compressor working after the front lifts, examine for a leak interior the air line that runs to the rear suspension or a leak interior the rear bags. Brush a mixture of dish washing soapwater on all of the lines and the luggage together as the air suspension is on. Bubbles will instruct you the leak.
First make sure that the model has the Hydractive, then check the manual level control, the hydraulic liquid level of the system and its behavior while test driving.
