I would also check to see how much LDS there is in the reservoir. Drop the suspension to its' lowest setting, turn the engine off, open the bonnet, locate the LDS reservoir cap (sometimes it has a steering wheel symbol on it), open it and have a look. There are, around the 'basket' some vertical slots, of two different heights. The LDS should be between the upper and lower slot heights.

I don't think air in system can cause hard ride. Maybe opposite?
Were newly mounted speheres the right ones? Original or maybe IHFS or any other?

May not be pertinent but following my burst pipe that emptied the system the fluid was low after repairs, i.e. nothing showing in the reservoir.
I added 2L but there was no problem with the ride, the steering became a little heavy but only a little.

It is a well-documented problem. The system is designed to operate with non-compressible fluid, and if either pockets of air - or aerated fluid - gets into the system, the action of sphere/valve dampers and hydraulic valves can become compromised. Cushioning should be coming from gas in the spheres, and not from air pockets. As well as crashy suspension, steering can also become notchy or under-powered.

LDS level is ok

Yes, I mounted IFHS comfort spheres, I heard only good experiences about it.

Ok, but are these the right ones?

Yes, it is ok! I bought comfort spheres for H3 system...
My car is very soft when I push it down by hand, but not soft while driving... Do height sensors could make problem, computer...?
