Bx rear end won't rise

Recently two high pressure lines behind the motor took a hit and pushed them out of shape. Caused them to rub together and eventually both pipes split. Hige pressure caused huge loss of LHM which mostly sprayed over the exhaust. Luck had it that I was just up the road from Cit mechanic. After a slighty bumpy and very smoky drive - dumped the car in his yard and waited for Christmas and New Year holidays to end for work to be done. The pipes replaced are listed on the invoice as 'steering feed pipe' and 'Security valve feed pipe'. Work was done but then the rear would not raise. All other systems operate as normal. Pipe to rear height correcter was removed and flushed and the car rose. I went for a short drive turned car off and it had time to settle. When I restarted the back would not raise again. Ran car for nearly half an hour putting in high position and low to try and shake it into action. No luck.
Things I am going to try - undo regulator screw and run then retighten - bleed rear brakes for air - check the rear height correcter for stickyness

Any other thoughts??

Air in the system? & is there enough lhm after having lost quite a bit? Height corrector sticking?

has the rear come up at all since the pipes were fitted,

if not maybe they have been conected up the wrong way round,

also it is very rare for the hight corector to stick, its usualy the linkage/external mechanisum/pivot on the rear axle cross beam that gets stuck,

Yeah, sorry i meant the height corrector link rather than the actual corrector.

Took off the height corrector and cleaned it out. It was full of gunge and didn't slide very well. Put it all back together but still no luck. The mechanical links seem fine. After that I ran out of time' light and patience. Next I will try and bleed air out of the system. Where is that done from? Can it be done via the rear brakes?

You'll need to do all of the brakes as they are dead end stops, but start with the rear as you might be lucky just in case any air is just down that end of the car.

the suspension circuit is self bleeding realy,

all you do is leave the car running with the bleed valve (12mm bolt head) on the regulator open for a couple of minuites, then hold the revs up at around 2500rpm whilst you close the bleed valve,

no citro blood should come from this point just air,
