today I saw something amazing.
I know that some citroen cars have hydraulic things (dont know the word) so
that they can go up on start and down on zturning off (a bit like
I saw a "C 5" today which was parking there for hours, then I realized that
the front off the car was going up a few centimeters, then pause a few
secponds and down again. I walkes around the car, and every few seconds the
front was going up and down again. I was screwed up and left the parking
lot. After half an hour i wanted to show this crazy thing a friend of mine,
but now it didnt move at all ?!?!?
So WhatTheFuck is going on with me or this car?
The only possible solutin I found for this was that the owner could turn the
car up and down with the remote control. Is that possible with a C 5?
PLEASE help me ..

The thing you are referring to is the hydro-pneumatic suspension, usually
referred to as HP. So the car does not have steel springs and shock
absorbers but bowls with a chamber filled with nitrogen inside. The car
has a hydraulic fluid pump which keeps the body on a constant level,
while the suspension work ist made by the nitrogen. This HP system has
been used in every top model made by Citroen since the 50's, you can also
find it in the smaller cars GS, BX and Xantia. With these cars indeed you
can adjust the ground clearance. When the engine is off, these cars tend
to sink to the floor, so they look like lowriders. Later Citroen cars
with HP suspension have valves in the hydraulic system, which prevent the
car from sinking when the engine is switched off.
HP is regarded as biggest technological breakthrough of Citroen ever,
this is it what makes Citroen special.
When the engine is running, I sometimes notice the hydraulic pump adjust
the car body level. This should not work with engine off. So I do not
exactly know wht you saw on that C5

I suspect it is mechanical.
There is a sphere specially for leveling the car after engine shut-down.
That sphere stays on pressure and if required it will fill the other spheres
to keep the car on level. That process is (afaik) mechanical.
But I could be wrong.

The C5 has an electric suspension pump. The car will adjust itself when the
engine has been turned off, but only for a few minutes.
When you unlock the door after leaving the car overnight (especially when
facing uphill) the car will readjust the height.
C5 suspension does move itself up when the steering is turned hard to one
side. I have tried to copy this before but have failed. It might work when
parked on uneven ground.
You cannot change the height by remote control.
All electrical systems except starting and locking will disable themselves
after being on for 1/2 hour or if battery is low. This ensures that the car
The C5 will turn its headlamps off if you leave them on. If you leave the
radio on it will turn off. If you leave a door open, the courtesy lights
will stop working.
When the electrical systems go into shutdown, the message "Eco Mode" is
displayed on the interior screen.
Hope this helps

This is actually a known bug in the system software of the car. It seems that
when the steering wheel of the car isn't centered when locking the car, the car
tries to balance itself every few minutes. It sometimes also happens when
parking on a sidewalk or a bumpy road. The solution for this is to center the
steering wheel when locking the car, or just wait for the ECO-mode to pop in
after 30min. :D
