UK MOTs have a specific section in the MOT testing manual for Hydraulic suspension:
You should take care when jacking up vehicles to avoid causing damage and refer to manufacturers’ information if available. Particular care is needed when jacking vehicles fitted with pneumatic, hydraulic or self-levelling suspension.

And for those interested, here is an extract from the May 2009 Matters Of Testing Mag from the transport office all about the C5 (X7 specifically):
Safely jacking the Citroën C5

One of our vehicle examiners recently asked whether the Citroën C5 could be jacked safely as he had heard that there may be a health and safety issue that could impact on the MOT test. As our information was a bit sketchy, we contacted Citroën for advice.

Citroën told us that they were issuing advice through their dealer network but would send one of their engineers, along with the latest C5, to our workshop in Bristol. The problem is that when the latest versions of the C5 (those with VIN prefixes VF7**************[VIN obfuscated, can be read by forum staff] or VF7**************[VIN obfuscated, can be read by forum staff]) are jacked and the wheels are hanging free, the manufacturer’s advice is to remove the LSD (suspension) fluid reservoir cap as there is a risk that the hydraulic reservoir could rupture. Citroën also advise that the C5 should only be raised using the designated jacking points.

Although the cap is readily accessible, it is not acceptable to remove it during the MOT test. As the axles are normally lifted independently at MOT tests, we asked Citroën if these procedures would still require the removal of the cap. We also asked about the possibility of using other mounting points, such as the sub-frame, to jack.

Citroën’s response was that the cap must still be removed when the car is jacked, but need not be removed where only one wheel at a time is raised. However, they would not support the use of anything other than the designated jacking points. We are therefore adding this advice to the Vehicle Specific Information (VSI) database.

Remember, it only applies to those C5s with the VIN prefixes mentioned earlier. An added bonus from Citroën’s visit was that this version of the C5 has an electronic parking brake, which we were able to test successfully with the roller brake tester. We will therefore also be issuing advice on its operation in VSI.
Of course we also know the C6 suffered from exploding LDS tanks, so my advice is always to follow the jacking up on high and removal of LDS cap regardless of VIN.

When I have been to get tyres changed/wheels balanced I have always (before setting out) taken off the cover that hides the reservoir. When I arrive I then loosen off (but to not completely undo/remove) the cap. Then, just before they jack the car up I raise the suspension to its' highest setting. The first time I did this at a tyre fitters they were bemused. They commented that they had always had problems with Citroens (mainly in getting their jacks back afterwards). When they did the work and then lowered the jacks they were surprised to see my C5 dropped back down to the top height setting and then remained there (in their experience a C5 would bottom out). They admitted they had learned something, and would try to remember it in the past.

One place I went to get front tyres from was on a slope. The fitter was going to jack up both front wheels, and seemed surprised when I explained this was not a good idea. I explained that the handbrake operated on the front wheels (he was sceptical). I asked him to jack up ONE front wheel, and then try turning it (he could see she was out of gear). When he found he could not turn the wheel he accepted what I said, and why it would have been dangerous. I hope he remembers this in the future.

The front struts for the MK II are the same across all models (but obviously different for left and right), but beware that the rears are different based on whether they are hydractive or not.

The leak back hose, cylinder boot and O ring are still available from Citroen, but the strut, rebound stop and shock absorber bellows are not.

It's really hard to say - but be grateful you haven't got the later ones that are on the X7 - there's nothing repairable on those - they need a complete new unit. :-D

I'd look at it this way - as the struts are no longer available new - these parts are going to become harder to find - so if if you are going to get one and replace it, then you can always check the o ring first. If it's the O ring, great - if not, you'll have a spare strut that that will be in demand for some time and you can always sell it on at a later date if you move the car on.
