Which is the correct precharge pressure for the spheres installed on ID 20? Probably this component is not available as a spare; so could I install other types of component (E.G. for Citroen CX)?

Hi Max -
Nice meeting a Goddess driver [8D]
There is just exactly ONE entry for DS (21/23) in the table found here :
http://citroeny.cz/servis/koule/koule.htm
At the bottom in this table you find the precharge pressure for each sphere type listed.
Remeber it's not just sphere pressure - but also the calibrated damper valve in the sphere that matters.

- as there are many DS owners here who knows about any tiny bolt on their cars [:p]

Hm, strange.
In a document I found on the HDD, DS/ID spheres are stated to be 700/700 ccm (front/rear), instead of 500 on that link. Pressure is 59/26 and bore is 1.65/1.65.
I think CX spheres would be ok for DS/ID, if it's running on LHM and if they fit on hydraulic cylinders. Wouldn't suggest BX, GS, XM or Xantia spheres because of different vehicle weight and/or somewhat different construction of suspension elements. At your own risk, of course.

Hm.
Checked in another document (this one from Citroen) and 59/26 bar stated for saloon. No info about sphere volume and bore diameter in that paper. Are you sure you don't have CX spheres on the rear already?
About sphere pressure and dampers, check my explanation here

About central bore diameter, you must remove spheres to check it. Also, I'm not quite sure that stated diameter corresponds to real one - a year ago, I examined GS spheres in father's garage, and bores were 1.3-1.4 mm front (instead of 1.8) and 0.8-0.9 mm rear (instead of 1.1) on genuine spheres. But as you will see, this bore diameter is not so important as other things.
