I changed the accumulator sphere and LHM last week on my Xantia. (Non anti-sink)
For the first 2 days the regulator cycled at once a minute and the susp stayed up for hours but then it went back to cycling once every 10 seconds and the susp sinking after an hour as it had done before. I'm not really worried about it as it drives fine and is reliable, I'm just curious. Why would it change it's behaviour for a couple of days then relapse???????

There is an extremely complicated test for the function of the accumulator sphere.
Run the engine for a couple of minutes with the car at normal height. Turn off the engine and sit in the boot. The car should sink a long way, then after about 30 seconds rise to its original height powered by the accumulator. No rise - no accumulator. If its really healthy it may do it twice.

is that why they collapse after you switch the engine off? I noticed lately that our blue one has started to do this, don't go right down to the floor but if you turn the engine off & get out by the time you've walked a couple of paces away the nose sinks.
I tried the sit in the boot test & ours didn't do anything, the only time I could get it to rise back up was with the engine running

Maybe you need to replace the accumulator sphere then !!rossnunn wrote:is that why they collapse after you switch the engine off?

Sorry,
It was a brand new sphere (not recon).
Yes I did the citerobics.
Yes it passes the boot test.
My question is how come after behaving for a couple of days (cycling once a minute, staying up for hours) has it now gone back to doing what it was doing before .

Then it's working fine!!!!
When you get out, even if you are a lightweight, the car is relieved of some weight, the car will rise because of this. Then the height corrector spool valve will be pulled out alowing the car to sink to its normall position.
The part you notice (as with most) is the car sinking to it's normal height, this is what a Citroen does!!

also the car rises fine when left over night - infact much faster than mothers later V plated estate. That takes a age to sort itself out even to the point that the brakes have no real effect at the first touch then they are fine after that. We're having all the sphere's done on that & renew the LHM
