Having owned my C5 Exclusive since new in 2003, I immediately notice the difference in a normal coil spring suspension. Citroen won't be the same now the Hydro pneumatic suspension system has been discontinued.
Your're totally right ! That demolition job started at the eve of the PSA Group ! Peugeot killed many high techs du to be on the Citroen CX (ie the HUD that was ready at that time -1976- !!).
Its a shame from technological stand point but from maintaining one is a nightmare. Parts are expensive, very few people know to work on them. Just spent a few hundred bucks fixing the main hose where it splits into three other hoses. I replaced that in 2017 and 20 000 km ago with original one. Every once in a while the fuse goes out on the pump, so im waiting for it to die and get it replaced. Its a pain to replace that fuse btw.
What a clever piece of engineering, I am so pleased to be the owner of 2007 C5 and disappointed that PSA have killed the Hydractive suspension system. You may as well do away with the brand now as it is no longer unique.
