Yep Simon - Agree.
Or the workout version : push the car back & forth while testing on the brake pedal. Guaranteed to get a nice red colour in your face
xantia sphere replacement
Moderator: RichardW
My car doesn't sink when it's parked but it drops right down at the back when I start the engine. I do know the accumulator sphere has seen better days but does this behaviour mean the anti-sink one has gone too?
My thinking, based on what I've learned in this thread, is that the anti-sink mechanism is de-activated when I start the engine but the flat anti-sink sphere is unable to take over. Once it's pumped itself up again everything seems to work fine.

Does it begin to lift first and then some time later suddenly drop, and then lift again ?reblack68 wrote:My car doesn't sink when it's parked but it drops right down at the back when I start the engine.

Or does it drop first, and then lift and stay up ?
If it drops first before lifting, it's probably the anti-sink sphere is very flat but not quite punctured. (EG still has a little bit of gas left)
Over night the brake doseur valve bleeds away all the pressure in the anti-sink sphere while the suspension stays pressurized. (This is normal)
Because of the very low gas pressure in the sphere, when you start the engine and the anti-sink valve is reactivated there is a sudden rush of oil from the suspension to the anti-sink sphere to fill it up.

thanks for all your replies guys i think i now can make sense of the system
the front accumulator sphere was changed 3 months ago and clicks after approx 35-40 secs so convinced that is ok
pushed down on rear corners and they both seem very flat similar to knackered struts on non cit cars ive had so points to dead spheres
it seems a safer bet to change all four corners and rear center at same time this will put this issue to bed i hope
have read other posts on hydraflushing system so think we will bite the bullet and do all in one go
think its best for piece of mind
then with full spheres and clean blood no doubt some other regulator/pipe will give up ghost but at least it keeps me busy
idle hands and all that..............
