This will be a variation on ESAC. A motor controls what those of us with conventional shocks would call a longer travel pre-load ring and gravity does the rest. No need for an additional fluid, compressors, pumps etc.

The air bag set up is what's on the back of my old Land Rover. The bags seem to last about 6yrs before they spring a leak - just long enough so you've forgotten how you did the job last time. I replaced one last week and found it was very easy. The hardest part was the effort of getting the jacks and various other tools out of the back of the garage. As a part for a 20yr old car it was available off the shelf and arrived in two days - at about half the price I remember paying last time.
When I set it to pump itself back up it did, except it didn't stop. The bag went up to full extension, with the pump still running and the car at a 20 degree list. One height sensor had snapped from plastic fatigue. That also arrived in two days and I've just fitted it this afternoon. I may have to buy more LR parts than I really want to but at least they're easy to get. If it was even more unreliable the local independent would same day deliver. Good job it's not a BMW
