Hi all I’m new to p38 world and my EAS is playing up I’m trying to find local garage near Kidderminster but really struggling to find anyone who wants to help and get to the bottom of the issue and fix it.
Is there any local garages people can recommend?
Also any mobile mechanics that specialist in this willing to travel and help?
Really appreciate any guidance and help.

Firstly Welcome to the madhouse :).

If you can give a bit more of what you mean by "playing up" exsquirts here could direct you to fix it yourself.
Most of it is pretty DIYable needing only basic tools, If you are able.

Most of the issues are down to leaky airbags or valve block or weak compressors.

So tell us a little more and if you are willing to have a go.

Have a read through the Late Wammers thread on testing the eas it may help you understand what is going on

Checking EAS compressor and diaphragm valve.

Remove inlet filter. Place finger over inlet. There should be suction. If no suction strip compressor and check piston seal and inlet/outlet valves in head. If suction. Remove compressor from mounts and remove blue pipe from compressor outlet. With compressor running put a finger over outlet, it...

You will be lucky to find any garage with the expertise to fix the problem without emptying your wallet with unsuccessful "fixes". It really needs diagnostics to identify the fault, then answers can be given to help resolve the problem.
Without the fault codes, things that spring to mind are the driver pack and corrosion in the white connectors at the foot of the A post in the passenger side footwell.
Look at the LZ map of members offering help, there may be someone near you that would take a look for tea and biscuits.
Might help if you put a rough location in your profile.
 
Like Marjon said . . . . What is it actually doing ? i.e. not rising, leaning to one side, going to high mode & showing fault ?

+1.

Normally the issues are (in descending order):

1) old leaking airbags.
2) Weak and worn conpressor, usually caused by feeding a leak. Sonetines this fries the thernal switch and it only runs using diag or shorting the relay. You can buy a refurb kit or I think @kurtjohnson10 had one for sale recently.
3) The connector behind the passenger side kick-panel has water ingress and the wires need cutting and soldering with heat-shrink.
4) The valve block needs a refurb. Kurt might be able to help here too.
5) The pins to the driver pack are loose and cause some odd behaviour.
6) The air-dryer is too old and has broken down contaminating the valve block or is leaking at the top somewhere.
 
I probably ought to see if I can add these to Wammer's How To. Might be useful.

Plugged diagnostics in states front left height sensor is the issue. Would you guys recommend genuine height sensors from Land Rover direct. Also would it be worth doing all four sensors in one go?

Anyone located near Kidderminster I’m willing to travel to fit new sensors in and recalibrate the system from anyone who knows what there doing happy to pay as all the garages I go to seem to have no clue like me.

Genuine sensors and I did do mine in pairs but it's your budget 😉
Put the car into full height on the suspension and check the lowest part of each suspension air bag for cracks or hazing on the rubber surface. They could well be worn out. 👍

The sensors only fit in one position so you cannot mess it up. If you have diag you can calibrate easily enough using either a stick on level ground or making some calibration blocks from some dowel or a broom handle. I think the methodology is in one of the documents I posted.

Only issue is you might end up grinding/ drilling the height sensor bolts out depending how rusted in they are. That would mean finding new bolts that fit.
