Another Xantai Supension question. Rear dropping straight aw

[lloydspencer]

I have had to leave my car parked up for several weeks after getting it.

I have come to the car this morning and started it up, warmed the car up.

I heard what sounds like a ticking or similiar noise (only does it if wheels moving almost like stone in the tyre) How ever the drivers rear wheel suspension hadnt gone up from its sunken position to normal. I lifted the car up and it raised.

I then drove it some more and it looks slightly lower then the other side.

After lowering the car and raising again still the same.

I then parked it up, turned the ignition off and leant on the back of the car. This caused the rear suspension to collapse.

I can only find topics on here for suspension that seems to collapsed when the car is started.

Lloyd, what model of Xantia is this please and what age...

[lloydspencer]

It is a 1.9td temptation Estate on a R reg (1997 registered i believe)

I'd say you may well have a ruptured corner sphere there Lloyd...

That's often the cause of the rear dropping suddenly when the engine starts. It'll be worth checking as a first stage, all the rear spheres (including the terribly mis-named rear anti-sink - it's actually the rear brake accumulator) and the main accumulator. It is likely the pressure regulator you can hear ticking due to the main accumulator being very weak or ruptured...

...and if the main accumulator at the front of the engine needs replacing, then the one at the rear probably does as well.
I found Cassy stayed up longer at the rear after replacing her rear accumulator.
