Sls problem w123 250 lang.

[barryw123250lang]

hi Guys and greetings from the west of Ireland,the rear suspension on my 250 lang 'gas'(petrol in my part of the world) was hard over bumps.I've just replaced the accumulators/spheres but things have not improved.The car previously never sagged and the fluid seems to be returning to the resevoir(pump ok).Tried manually moving the 'fill- empty' lever with the car idling but nothing happens(no movement).Thinking their was an air lock I 'cracked' off the banjo fittings on the struts-air and fluid came out,the rear dropped a bit but has not re-levelled.It seems the valve is not refilling the struts..I'm using citroen type LHM fluid..any help appreciatedBarry
