Forgot - 1 click every 50secs (while driving) is quite acceptable. A click every few seconds usually means a pooped Acc sphere.

As said, check the vehicle height when set on Normal.

Also do a bounce test:
- engine running, car stationary
- press down on the front, and it should go down fairly easily by about 10+ cm, then come back up
- do same at the back (or sit on the boot ledge), should go down 15cm or so, and return
You should feel real softness.

If the height lever is set to Highest, and you do the bounce test, you will feel what it's like to have spheres without gas - solid.

Mine passes the bounce test. I did that before purchase. :)

Where should I measure the height from pls ?

If the front bumper is grounding out I suspect your problem may be the front struts sticking, if your spheres were flat (lost their gas) you would not get any suspension travel, it would just bounce, if a sphere breaks internally that will cause that corner to bottom out?
It may be worth checking that your height lever and correctors are operating correctly and don't rule out the hyd pump as a knackered one will struggle to keep up.
I also recommend Pleaides Martin is a wealth of Citroen hydro
Your very lucky if you don't have any leaks and all your major suspension components are working as they should after 30 odd years, otherwise it can become quite costly.
Yes !! I have no leaks. It had a new spider / octopus fitted in 2016. That was the last lhm change as well
Since the the car has done around 2000 miles I think

I think Haynes lists the procedure, but this is the pukka Citroen data:

:!: Car body MUST be adequately prevented from dropping suddenly if height adjustments are made. NEVER rely on hydraulic support when working underneath. A garage flatbed lift or pit (with ground level reference point) is the safest option.

Many thanks. This is very useful.

I have identified that possibly the front height correctors arnt functioning correctly. ( got two fat people to sit on the front bonnet. The car goes down but didn’t auto correct it’s height within10-20 seconds whilst still under load. Apparently this signifies the correctors need looking at. So that’s on the list for Friday when it’s in the garage.

Thanks all. Some excellent information posted for me. :)

As well as the mechanicals and the not-too-long-ago LHM change, it might be worth running the old bus on Total Hydraurincage for 1500-5000km. It's Citroen's official and recommended LHM system cleaning fluid, and works really well.
1 × 5L is sufficient for the system.

As well as looking at the height correctors, check that the long lever-linkage rod is greased in its guides, and free to move properly.
