Affects: BX CX Xantia XMThe suspension spheres are more than likely done for. Over time, 6 to 10 years on average the spheres slowly lose their pressure. Each sphere has a diaphragm within. On one side the LHM fluid, on the other, nitrogen gas which during use is the compressible medium. If the diaphragm becomes breached or porous the gas side fills with oil. That sphere will then be about as useful as a chocolate teapot. At this stage there is no other cure other than to replace the unit (pairs are highly recommended). Spheres can be regassed or 'reconditioned', but this is only possible BEFORE they reach this stage. Buying new ones has become the common trend, mainly as replacement units are now quite cheaply available. https://www.eurocarcare.net/spheres.html
