Citroen C5 X7 height difference between front left and right side

[nomad123]

Hi guys!
There is 5mm diffrence between front left and front right suspension height.
Front right side is 5mm lower than the front left side.
Measurements from the centar of the wheel hub to wing:
Front left : 42cm
Front right : 41.5cm
Rear left : 39cm
Rear right : 39cm
Measurements where taken in garage with flat surface and tyre pressure is correct at 2.4 bars at each wheel.
I have also measured at different locations and its the same with 5mm diffrence.
Changing ride heights also doesn't change anything, there is still 5mm diffrence.
Wheels are 19' with new Michelin Pilot Sport 5 tyres so thread wear is the same.
C5 X7 2.0HDI 103KW HYDRAULIC SUSP.

Any advice of what could cause this is appreciated. Thanks!

That's not a very accurate way of measuring - see the guide here: viewtopic.php?t=70745

Ride heights need to have the correct procedure followed to check if these are within tolerance. There are too many factors to consider here, like tread wear, angle of the vehicle on the surface (surface may appear flat, but 5mm is a very small difference), then there's the suspension geometry (allowing for worn components / bushes etc.) or the strut itself, amongst other things.
