Tool for setting twin axle ride height please.

Friends

I am stuck. My 4.8is Ride Height is all over the place, when viewed with INPA.

Each corner is showing a massive variation in the numbers and my attempts to re-calibrate it using INPA have all failed. I have dedicated weeks to reading and searching the forums in a vain attempt to correct my ride heights using INPA and it is just not happening.

I measure the height from the ground to the middle of the arch/fender in a vertical through the wheel centre.

I then note the difference between that measurement and the INPA default for my car (20" wheels on Sports suspension) this is 707 for the fronts & 709 for the rears.

I then enter the calibration mode and enter the difference into each section.

Result? The car is still not resetting to it's default and is out of range on INPA which in turn causes the suspension to go 'inactive'.

I have tried different routes and different suggestions but none work.

Door Open.
Door Closed.
Engine On.
Engine Off.
Ignition Position I
Ignition Position II

It is driving me insane.

My compressor is working fine and has just been rebuilt with the fantastic bagpipingandy kit. I can raise and lower it using INPA and test each valve etc. The corner sensors are all good and I have no leaks.

It just needs re-calibrating.

But I cannot get it to reset to the default values/height.


What is the simplest tool that I can use to reset the heights to default and get it calibrated correctly so that it stops the 'Self Leveling Suspension Inactive' kicking in all the time?

I have a WIndows 10 machine that is running INPA and a cable with pins 7&8 linked.
