Hi Guys,

Can anyone tell me what these should be, as my garage needs to reset them but no ones seems to know what to!

Standard 790mm +/- 7mm
Access 730mm +/- 7mm
High 830mm +/- 7mm
Low Profile* 770mm +/- 7mm
Extended* 850mm +/- 7mm

Not sure if that is from the wheel centre to the edge of the wheel arch or the ground to wheel arch but it should be pretty obvious when you get a rule out.

*Low profile and extended are calculated by the ECU and are not adjustable.

Sorry to revive an old thread, but just wanted to check with those in the know...

Do those ride height measurements apply to BOTH front and rear? If so, my arse end is sat pretty low (about 1" lower than the front) - and already was, before I changed the airbags.

Tried to calibrate with EASunlock just now. My driveway is somewhat less than level, so went and found a car park that I know is almost perfectly level. Quite alot of inconsistency between measurements... On my driveway, the right side sits visibly lower than the left, but in said car park, it's the LEFT that sits lower, although difference is less acute.

I want to find another 'level' area just for a comparison before I fiddle with any calibrated settings.

The measuremments quoted are from a level floor with tyres at standard pressure. Standard height from centre of wheel to wheel arch is 470mm extrapolate rest from that by deducting 320mm. Heights same front and rear.

You'd want to measure the ride heights by removing (or not if you have the official LR tool) your rubber bump stops and then inserting a block of the appropriate thickness between the lower arm and the bump stop pad on the upper suspension arm. Then use your EAS diagnostic software and drop the suspension and read off the height sensor readings (bits) for the appropriate heights. Then store whatever reading you have read off for the respective heights.

Any other method will not be as accurate as it be will inevitable that other variables that may come into the equation.

Ok, confused a little here... Your original post suggested values measured from the hub centre, not the floor... And tbh, made sense on that basis.

Plan now is to make me a 'measuring stick' that I can locate over the hub nut, and draw lines on to represent said heights... This I can quickly move from wheel to wheel, without having to fanny about with lining up a measuring tape each time, and calibrate EAS to the same marks for each wheel...

You will find that each time you adjust the height on one wheel it will have an effect on the others to some extent.So it will be a bit of adjusting one then back to the other side to check etc.It can take quite a bit of fiddling to get it correct all round.I guess that is why Land rover made height calibration blocks to lower the chassis onto .

The values quoted by Datatek are from the floor. Either use those or deduct 320mm from all of them to get measurement from centre of wheel to wheel arch. Still make sure all tyres are correct pressure and you are sitting on level ground.
