Question

please help? thanks again

Answer
You are very laconic. What car, what system? What was the problem?

Otherwise I think that will be a Discovery II ACE fault. Check / top-up fluid level. Check the hydraulic unit (placed at the right hand side of the under-body chassis). That has a metal filter at that bottom. Screw out the big headed screw with an allen key (Its a large one).
Check it for cleanness.

Then at the front of the block pull the connector out and spray It with some contact helper spray (it's the pressure transducer).

Finally you can bleed the system if you fill the reservoir, then go out and at 50km/h or more, do some quick and large steernig, to force the hydraulic unit work.
