Yesterday reread it again, but this time I took some notes, all the info there is top quality ;). I had this bookmarked on my other comp and kind of forgot for its existence.
Still, I would ask again the same question I've posted there - for Hydro-Pheumatic (non-Hydractive nor Activa) suspension, so it is 6 spheres, with Anti-sink valves (the 6-th sphere is obviously for the anti-sink feature) and 2+6 pump, proper depressurization should be done with the car on LOW ("half tyre" sign :D ) and engine shut off, right???

No. Full height (lever as far as it can move), and with the engine RUNNING. The foot brakes on all Xantias are powered, not power assisted, and need the pump turning (so the engine has to be running) to provide the pressure.

Yes, I've messed up again, my bad :D.
Yes, for the breaks is understood, thanks!
I was asking about the full depressurization at the conjecteur (12 mm screw at the accumulator sphere), as I was asking that at the "Spheres, Hydraflush..." thread mentioned by CitroJim.

To depressuiise a car with anti-sink, you need to first depressurise the suspension by setting it to the lowest setting with the engine running (to keep the anti sink valves open). Wait at least 30 seconds after the suspension appears to have reached the lowest point before switching off the engine.

Then depressurise the main accumulator by releasing the 12mm bolt.

OK, so when you are depressurising the system you lower the car to its lowest setting, leave the engine for a minute or so, turn it off, turn that screw by one full turn (no more; there is a small ball bearing as a seal, and if you remove the screw the ball bearing goes walkabout), and listen. You should hear a whistling that will lessen over time. Once it has stopped wait for a minute, just in case, and then the system should be de-pressurised.

When I was ready to pressurise the system again (and all of the work had been done) I would start the engine up and wait for a minute or so (to allow any air to get back to the reservoir and escape to atmosphere), then tighten up that screw and raise the car to full height. Next, check the LHM level, and top up if required.

It has been over 5 years since I had a Xantia, but they are easy to work on if you are careful.

Was it Hydractive?
Think xantia_v6 is holding the truth regarding the non-Hydractive's.
:yes:

It should be the same method to bleed a Xantia regardless of the suspension system.

While writing my last post, I saw yours, but mentioning the opposite regarding the engine, hence my question... maybe you've corrected it or I didn't saw right initially :D
OK, so finally, the engine should be OFF prior opening the screw ;) 8-)

I had forgotten about the anti sink system, so there would have been pressure left in there with the engine off too soon. Bottoming her out and then waiting for about a minute deals with that.

Yes, this is the other aspect, you have to wait 30-60 seconds with the car on LOW and engine running, then engine OFF and finally opening the release screw.
Actually, I saw this just yesterday after rereading Jim's thread :D
