OK gang, I've looked everywhere and have not found a description of what is inside the hydropneumatic device fitted to W108 rear axles.
Is this a typical nitrogen-charge-behind-a-diaphragm scenario (this would explain why they don't last forever) or did the engineers do something clever? Well, the self levelling is a clever idea in itself, but were they able to avoid the need for a diaphragm and a nitrogen charge... What is the failure mode for these devices? Is it just that they stop performing the levelling function (loss of fluid) or do they lose the nitrogen charge and then become very firm, producing a harsh ride? Numerous people have told me that this device doesn't last and doesn't make a big difference etc etc, but people say the same about the self-levelling on MB wagons and that's certainly not a troublesome system if you understand it. Has anyone actually seen one of the W108-fitted devices in pieces, or a diagram of its composition?
