andy_k is correct, the car does go low when the pressure is down. This means that the SLS system is used all the time, not just when the car is loaded.
Thank you
So I'm surprised that to bleed the system you are supposed to put some weight in the back of the car.
it's not to bleed it it's to initially prime it - the system is self bleeding. I can only assume the 120kg weight ensures that the return valve stays open longer than it would do with no load
Also, you shouldn't need to load the car to check whether the spheres (accumulators) have lost all of their gas pressure, as it seems that the spheres are in constant springing service in parallel with the coils and when the spheres are absolutely hard there will be no give in the suspension at all.
Nobody said that you had to (or at least I don't think they did) - once those spheres fail the suspension does get very hard there is still some give but very, very little - I can only assume that is caused by the fluid being corrupted by the nitrogen.
