How many spheres does my C5, Xantia or XM have?

If you are unsure about the number of suspension spheres your CITROËN has, our technicians are available to advise you on the number, calibration and location of your suspensions. Whether it's Hydractive or not, sport or comfort mode, our advisors can provide you with information and help you place the perfect order to restore your CITROËN and its hydraulic system to its original efficiency. The number of spheres depends on the Hydractive system. To determine whether or not your CITROËN is Hydractive, consult our FREQUENTLY ASKED QUESTIONS section, where you will find all the answers to this question.

What is the purpose of the membrane inside my hydraulic sphere?

A sphere is divided into two separate parts (two sealed compartments) by an extremely resistant, deformable elastomer membrane. The upper part of the sphere is filled with nitrogen (a non-toxic, non-flammable gas), and the lower part is filled with LHM oil. A valve-equipped orifice at the bottom of the sphere allows oil to pass through the cylinder to the actuator. Once your Citroën has started and warmed up, the oil is pressurised by the pump. It then presses on the membrane and compresses the nitrogen to a perfect balance. Once underway, the nitrogen pushes back the LHM, which returns the suspension arms (via the piston) to their starting position. The engine drives a high-pressure pump coupled to an accumulator, which distributes the high-pressure hydraulic fluid to the various systems, such as the brakes and power steering.
