I've noticed my car seemed to be a touch low on one side, was hard to tell with parking in a snow bank for the past few months
So, after a few years of having an IIDTool, I've decided to recalibrate the suspension.
But my question is that the instructions and worksheet have you calibrating the left to the right, or vice versa. How would I figure which to do, is there a certain height I should be trying to achieve?
And what about back to front (or front to back)..
Also, once I've re-calibrated the EAS, the original values that have been saved will be useless, how do I go about saving a new value into the original slot? (This might be obvious if I was to look )
Set each side to be equal, then adjust front and rear to match a certain value from there.. I just needed to read a bit farther into the manual.
On another note, I did up a quick little spreadsheet to do the calculations for me. It's simple calculations, but I figured I can just upload the spreadsheet onto my phone for a quick way of doing it in the future.

Should sit a bit higher at the rear, with 466 mm at the front and 485 mm at the rear when measured to the centre of the wheel thus:
Clearly test on a level surface, full tank of fuel or ballasted accordingly, no additional weight, correct tyre pressures, engine running etc and Tight Tolerance mode.
Hope this helps and feel free to post your spreadsheet on here.

Never quite understood the weight thing - its self levelling suspension within a few mm (in TT Mode) so the weight should make no difference. Or have I missed something?Mark.

I don't understand the weight thing either, however, the drivers side heights did change on me after I got out and read from outside. They changed by 1..
As for fuel load, I'm doing it with a normal fuel load (ie.. almost empty), just put $50 in yesterday..
It's surprisingly hard to find a level surface these days, everywhere seems to have a slight slope to it. So off to a parking lot I went.

The weight and distribution does make a difference as the sprung mass is not isolated to the air in the suspension alone. If this difference matters to you or not is a different question but the procedure I have outlined is in accordance with JLR.

I had about 1/2 tank of fuel, but about 50 pounds of other stuff in the back, so it should have equaled out. When I get new tires, but before I go for an alignment, I'll redo the measurement with a full tank and nothing in the car. That's assuming I'll be able to afford fuel after new tires of course.
This is the measurement I took beforehand, and the spreadsheet I made.
And this is after re-calibrating.
