Hi Dave, Cheers for your quick reply and warm welcome here! All plastic linkages of the hright corretcors are fine, that's why it is puzzling me why one of the height selectable settings is not functioning! (2nd setting higher on interior height selection lever) My car lowers a bit when I switch off engine, strange when I know that all spheres are new! I am suspecting that I have a leak (I need to top up LHM monthly), and maybe the system is sucking up air from somewhere! May that's why when I drive in the morning, the rear feels stiff, but when I lower it and fully lift suspension, it feels better - I am assuming that with this, I am like bleeding/priming the system. I've read a lot that cleaning the LHM tank filters improves a lot, so I'll wait until an explained procedure is posted and try it out! Cheesr fo now, take care, Stefan
