I have problem about rear suspension sphere in xantia (xantia 95 with antisink sphere).As I know, Sphere should be check pressure every 1 year or 20000 Km and regas or replace new one if pressure drop under standard.But in Xantia ,especially in rear sphere, sphere pressure usually drop under 20 Bar in 3 month or less than 5000 Km.Do you have any suggest to improve sphere life?
Thanks

How do you know the sphere pressure drops under 20bar ?
- is that what your Citroen garage tells you ?
If that really is what happens, then you have defective spheres, and you must have new spheres fitted. They should last at least 4-5 years before you can feel any noticeable detoriation in suspension.
If you get your new spheres regassed every 3 years, then the spheres would last almost forever. The problem is if you wait too long, then the remaining pressure in the sphere may be too low for reliable regassing, as the membrane is pressed against the sphere wall inside, and then shears. Then the sphere will either leak quickly or not hold pressure at all.
