yes, the fronts both move on command from the dash switch to what ever height i set it to but the left front always remains higher.have swapped fronts over, made no difference so do not think it is sensor.

So, how does the ecu know how to position the suspension except by feedback from the sensor?
If you hadn't swapped them over as a test, it points to a bent sensor arm or other damage allowing a false height reading to be sent to the ecu ....
I'm running out of ideas ... anyone?
Do you still have the old sensors to try?
BTW, what year is it?

thanks for you reply, yes have old sensors but it was the same so i changed for new. The car is 2000 4.6, like you i am completley stumped. Have a good look underneath and can see no damage.

hi datatek, no, that's the problem it just will not lower at all. Always sits half inch higher than other side.really strange. All others move on command.

So, what is the difference signal wise between the rocker level switch on the dash and the laptop connected to the ecu?
As i said earlier heights are plus or minus 7 mm and ideally with a bit count within 2 side to side. But that is utopia. You may never get car absolutely level. To get the front level which is important to minimalise dropping when valves open to equalise pressure, you may have to lower rear at the opposite corners as needed to achieve that. Where the rear ends up is then where it ends up, as long as it's within the plus or minus 7 mm side to side it is normal.

Using the "Go To" function in the calibrate tab of the EAS software, can you command it to access height, motorway height etc?

yes, when i change heights using the ( go to ) function in the calibrate tab it moves no problem plus when i use (get sensor heights) it changes ok, i just do not under stand why front left is higher. Not sure if this is relevant but today when i got home from work i had it locked in motorway mode (inhibit switch on) i took a measurement of the front and they were both the same height? but, when i turned inhibit switch of and took it standard height it reverted back to higher front left. when i am calibrating and make changes using software i can here the valves clicking and it seems as if the height is trying to change but its like its sort of stuttering, sorry but its hard to explain, then when i take a measurement its still the same. i have tried calibrating by changing the value by 1 and writing it and also changing the value by 5 and writing it, right down until its out of range for the ECU. I have a spare driver pack that i am going to swap over at the weekend, do you think it would be ok to bring the front right up the half inch to get as close as i can to match the front left? just want to get within the 4-7 mm tolerence.
Thanks in advance.
Paul.

If all the height functions work from the button in the car and from the go to function in the EAS software, I can only guess that you are trying to take it out of range, are you sure your height measurements are correct? The ground needs to be flat and the tyre pressures correct.
Can you adjust the setting for that corner at wading height or motorway height?
