After 12yrs is it worth considering changing the spheres?

Do the aftermarket spheres offer any benefits or is the quality vastly inferior to OEM


I suppose it can be done slowly and change one every payday?

Hello,
Original balls last a very long time.
If your C6 is still springing well, you can wait to switch.
Removed balls can be checked with a ball tester to see what taring pressure is still present.
Original balls can also be refilled because the 3-fold membrane is of high quality.
Replica balls have a cheap membrane and a narrower flow channel - only original balls are really good.
Always change all balls - spring cylinder and hardness regulator.
Greetings Wolfgang

Hi Paulius,
I believe they are available from Citroen still but need to be ordered, as i bought a full rear set this time last year, but they are selling the Eurorepar brand ones as well and they are less than half the price of the Citroen original spheres with the logo on them.

Im not sure what the difference is but if i had to guess it must be something probably to do with the membrane on the cheaper branded ones and it relates to the PSA parts supply business of Peugeot.

Anyway, the Citroen logo version of the spheres are around 180 euros each if i remember the quote. Hope that helps.

The reason why I was looking to change my spheres was the car seems to be able to cope with normal road surfaces but short sharp jolts eg expansion joints or slightly raised drains can be felt as a jolt through the entire car

I have seen videos of the hydropneumatic suspension, when new, tackling cobbled roads and I don't have faith that mine could

That appears to be a shock absorption issue rather than a suspension issue. Unless your C6 is a 2.2 HDI, the Amvar (variable damping) system (inside the struts) would be responsible for such behavior, not the spheres themselves.

Check and correct ride height first, see if there are any faults listed (Diagbox), check tire pressure and also the tire settings in Diagbox (make sure XL and the correct rim/tire combination are selected).

I've managed to get Diagbox 7.62 working, slowly getting to grips with it

Only fault in the suspension seems to be U116

The AMVAR seems to be set at 8-9 "steps"

I have included a couple of pictures......wondering if the rear left sensor voltage is an anomaly?
