Discovery 4 sdv6 GS Dreaded suspension fault showing

Hi all I'm Tony I'm a newbie here ! , I have a discovery 4 3.0l sdv6 GS and the suspension fault.is constantly showing on screen , I've changed the front valve block for some reason hoping that was it but still there ,pulled fuse last night left and the only strut that showed any difference this morning was the front passenger one by half a centimetre that was it surely not enough to show fault , has anyone else had this problem no fault codes showing at all just says suspension fault every time i start car and constant but still raises and drives fine any help appreciated please ,would it be worth changing the rear valve block also or not is there a possibility it could be that one ? Thanks for your help in advance ,Tony

Hi Tony
You really need to scan it with a decent diag what did you use ?? just changing parts in the hope of fixing it will prove expensive.

It could be something as simple as a weak battery, not uncommon for what you have

Hi thanks for replying, I'm not getting any codes coming up at all nothing stored nothing showing ? ,I'm using Delphi scanner running 2022 software but not getting anything ? I've just raised it till morning and pulled fuse measured height to see if any drop tomorrow but can't get any codes

I'm not that will scan properly a gap tool would be better. What voltage reading are you getting with ignition off ?
