Citroen c5 - Suspension Issue with speed bump test

Citroen c5 2.0HDi Exclusive 2008

Front right suspension was replaced with a new unit, however rear suspensions have invalid behaviour where back of the car literally jumps when crossing over the speed bump.

Looks like rear spheres need re-gassing. Might even be a blown membrane.

this is a typical problem with the height regulator. it also occurs in other hydropneumatic Citroens, other causes are worn suspension spheres, too low level of the LHM oil, leakage of the high pressure piping system, or defective sensors.

you have too high lifted the back of the car, it's not the fault of the spheres better ride to the site reset the height of suspension

the problem is that a Bosnian is driving a Citroen xD

In my opinion, it looks like you car wasn't in a normal position from the beginning. Or was it? Looks like it was set at least one step higher than normal. I noticed that mine gets a lot stiffer if it is not set on normal. Did you found out what the problem was?

Rear axle is too high, didnt you scratched your back somewhere? The height corrector can be damaged or with bat setting. Also there need to be checked. When you push the rear boot to the ground with hands, it must be floaty nice and soft suspension. If not = service.

Is that problem already solved? If not you need to go to a Citroën repair center. I had a similar problem, the hidraulic pump broke and had to be replaced. Then had to be reprogrammed, and the hights measured, and reajusted. So, this is no job for amateurs... Good luck and enjoy your fantastic car!

Looks like back is too high. Leveling issue (you need to calibrate with lexia or in citroen garage) or worn back sphere.

This video is FAKE.
Every Citroen behaves that way, if it has Hydractiv suspension and it's set in higher position, like that car on the video. I have the same model of that car with that type of suspension and I clearly see that it's on higher position of suspension.
That position is meant to be used only when going slowly over high obstacles, deep water etc. It's *NOT* to be used during normal driving, because natural consequence of lifting or lowering that suspension is that it becames much stiffer.

For the suspension to be flexible it must be in the normal position, as it is in the upper intermediate position it no longer works correctly and bounces

Bonjour, j'ai exactement le même problème mais sur ma roue arrière gauche. Les suspension sont en position normales et les 3 autres suspensions ont une réaction normales. La voiture est de 2015 et as 48 000 km. Auriez-vous une idée de la panne? merci beaucoup.

Hello, I have exactly the same problem but on my left rear wheel. The suspensions are in normal position and the other 3 suspensions have a normal reaction. The car is 2015 and has 48, 000 km. Do you have any idea of the breakdown? Thank you very much.

[picardenter]

Blimey, my mk1 C5 rides better than that and it's 16 years old with a 137, 000 miles on the clock. Something's not right in the Hydraulics I would imagine.

Or the pressure in the whole system in the rear suspension is blocked somehow. Maby some valves don't want to open or sth. You have to find someone with an appropriate knowledge about this kind of suspension.

Hello guys. Anyone sorted this problem? I changed almost everything without results… i didnt checked the spheres yet … but if someone solved let me know thanks

[nirmallakhara]

Car in slow motion doesn't mean that it will bump slowly video was slow not the car try at 5 kmph in india you won't be able to drive your car everytime you'll bump and you will land on another bumper😂

Ребята что это такое. На моем с5 происходит тоже самое. Перед проходит хорошо лежачий, а жопу подбрасывает. При езде по дороге, проблем не выявлено. Помогите разобраться.

Süspansiyon yüksek kademeye getirilmiş konfor modunda değil ve zaten o kademede hiç yaylanma olmuyor ve sistem maximum basınca ulaşıyor . Ya kasıtlı yapılmış yada bilmeyen biri çekmiş bunu

you have back too high ... this is no problem with sphere ... check height
