Me again

This time I'm struggling to calibrate my EAS with my Nancom. All wheels were at 48cm from wheel arch to wheel centre until I refurbed the block. Pipe 3 and 4 were swapped round. They are now back the right way around. Now, however, the wheels are slightly out. One is at 47 another is at 49. Attached in a picture of the live readings at standard height.

I've jacked each wheel in turn making a note of the live readings when they are at their proper heights (ie 47cm for standard, 51cm for high etc). I then got a load of "correct" readings:

Tyre--Mway--Standard--High
FL------79----------87--------113
FR------91----------103------128
RL------84----------99--------125
RR------82----------95--------118

So I then enter these in to Nanocom and select STORE.

But immediately I get EAS FAULT - Incorrect Height Data and I have to reset the fault. When I do, everything revets back to it was with the readings (for standard) shown in the pic.

However, it never makes those readings. It shows Target Height and current live height, but it never ever makes the target height. It doesn't try either, it quite happily sits there. No errors. Nothing flashing. No movement.

What gives?

Ah ok, it was a method I picked up on rangerovers.net: Depressurise till its on its bump stops then jack the body up (not a wheel) until the body is raised to the height you want from the wheel centre.

I'll try the trial and error method. It just means finding somewhere flat as my drive has a slope

Looking at my picture above, I bet pipes 3 and 4 that were the wrong way around feed the front wheels? Would I be right?

Yes 3 & 4 are for front air springs

No wonder its out then. The previous owner has had it calibrated with the pipes the wrong way around. I'll try and just swap the values for the front wheels for each of the ride heights and that'll probably sort it anyway...

Edit: Just been out and done that and it now gets to target heights ok.

That won't work, well not precisely.
The readings that you are getting are readings from the height sensors but these are not precision engineered items, every one is slightly different.

Yep, I realise I'll have to calibrate it if I want it spot on. But it was way out after swapping pipes 3 and 4 back round to the way they should be. Now it gets to the target values ok. I just need to make sure the targets are right!!
