Asking for advice in where to look.

So the Range Rover went in for sill and arch work 5 weeks ago and a top job the body shop has done, it was picked up after the work and went to the next operation work at the local garage, the front subframe.
This has now been done, new mot and now mobile once again.....BUT.

Now I'm having air suspension faults, the front is higher than the rear by a considerable amount, when they where checking the sensors on their diagnostics it was showing the rear left not reading any signal.
They have changed this today and they recalibrated ( I think ) but the front is very high still.

Would a recalibration help or would it be better to lower the front only and not touch the rear?
I have the early Gap Idd tool (non Bluetooth)

Faults before the sensor change are as follows,

ox4 abs module rear left speed sensor plausibility
ox81 air susp can bus
ox82 tacho A missing signal

EAS ox64
1 articulation validity fault
2 ox32 can bus fault
oxbd ebv function fault received from ABS
transmission ox95 canbus speed general fault.

I must stress than NO faults where on the EAS before the work started as shes been very reliable in this area.

Any help would be greatly appreciated.

(with all thats gone on this year from house electric's, trailer brakes and my horse been hit by a car (she recovering) this is not what I need next) If it dont work.......burn it!

If the IId tool cant fix it.......burn the FF.

If the FF cant be fixed......buy a Land Cruiser!

If the LC cant be fixed..............................................BUY a horse !!

Is the graphic on the 4x4 info screen showing the front as high?

Could one or both of the front height sensors have swung round when disconnected, so now have the elbow the wrong way so giving a false reading?

No other ideas, sorry.

Thanks mjdronfield
The sensors all correctly facing the way they should, ie arm facing out wards and connecting rode vertical

Danb, yes they did disconnect the battery as I messaged him about the steering left/right thing after reconnecting.
It was level when I picked it up an all good. If it dont work.......burn it!

If the IId tool cant fix it.......burn the FF.

If the FF cant be fixed......buy a Land Cruiser!

If the LC cant be fixed..............................................BUY a horse !!

after I swopped the front struts and ride height sensor I recalibrated mine (10 mins using the latest IID tool) not sure on the older ones. Worth a try? 2011 L322 Autobography - a lot of bells and some of the whistles...owner with no idea!
