My joy at repairing my suspension prob. was shortlived.
I have been told I need a new hydraulic pump.
Are the 2.0 activa ones unique ?
Could anyone let me know, please?
Had new pump on today problem solved
Short Lived Joy Now Happy! Now fuming!!!!!UPDATE!

Really peed off now.GRRRRRRR
On changing the pump all was wellfor 3 days
Went to satart up but car would not rise, stuck in low with STOP light grinning at me.
Since then I managed to get it up it went o.k. for a few dats but between yesterday and today it has variously
A Got stuck on high position with light on refused to go down.
B Wouldn't go up today only half up with bloody STOP light refusing to go out.
C It was stuck on high , no way would the front go down ,the back yes.
Only way to get it moving was to park it half on the high kerb again.
( Neighbours must think I'm crazy.)There she goes up and down as she should
Once on the slope it goes up and down a lot better but on the flat the old symptoms are back. To get it to move I have to rev it to 2000 rpm.
I don't think the new pump is ****ged ,but what is the bloody problem that has got me ( A Pastor) swearing like a trooper!!.
I can't hear the acc sphere ticking, but I'm spending a lot of dosh and not getting results and don't want to keep changing things willy nilly

Clearly the pump isn't producing enough pressure. Is the power steering working? - As you probably know your car (assuming its after 94) has a 2 outlet pump, the majority powering the steering and the remaining 2 cylinders powering the suspension and brakes.
The basics of the circuit are the same for all cars - pump, regulator/accumulator then the safety valve which also distributes the pressurised LHM to the rest of the car. As the light is reluctant to go out and the regulator isn't cycling its a fair guess that the warning light is telling the truth and the thing just isn't developing enough pressure.
Why? - My old friend - air may be the problem. - Relatively easy!
Otherwise - and possibly the first stop - is the drive belt tight - but this would probably squeal under load and affect the steering.
Another possibility is that the pressure relief bolt on the regulator has been removed entirely instead of just being slackened by no more than 1.5 turns (0.5 is often enough) and the ball bearing has been lost - so allowing the fluid (or most of it) to re-circulate rather than fill the accumulator and operate the regulator valves and the safety switch etc. If this was the case the steering would be normal as the regulator is not in that circuit.
I suppose the easiest way to check is to place a tray underneath the regulator and remove the pressure relief screw and see if the ball bearing falls out. If it doesn't you may be able to find it with a bit of wire. Having found it stick it back with a dab of grease and replace the bolt.
If the ball is missing any new one of the right diameter will do the job. There may be a link to a BX parts book on this site - the size is stated there. (Not the same size as the non-return valve!)

As I said the pump is a recon one from g.s.f. fitted by a Cit specialist.
The weird thing is . is why is it intermittent. Surely if the pump isn't giving enough pressure it would do it all the time which it doesn't.
As i mentioned earlier it was fine for 2 days then bad one day then oo.k. another.
Just going out to start it up for school run.
Let's see!!

Calm down !
Seems that panic has caught both you and your mechanic. The pump will not build up pressure if it takes in air from a leaking reservoir feed hose. You can not see the hose leaking as it is under vacuum.
* The classic problem *
The large diameter rubber feed hose has a nasty tendency to get brittle and develop rather deep surface cracking - especially over the studs.
Check it carefully - and if any doubt replace the hose or at least cut off the ends to get a fresh piece over the studs.
You can use PVC garden hose as an emergency repair, but note that such hosing may collapse from the vacuum on longterm use.
At the studs use a larger ring of rubber hose to thicken the feed hose to even out the clamping force from the hose clamp.
