D3 stuck on it's guts

I did jack it up before I rebuilt the air compressor but that didn't help.

After I put the rebuilt compressor in, the car pumped up to an acceptable height. but the red light is still on the dash. I can clear it with the nanocom but it comes back immediately. Using the llams I can make it go to extended height. I believe there is some calibration I need to do with the ride height unit, but I don't know how to do this.

Even with the red light on, warnings about being speed limited (I don't think that works cause I've done 110km on the freeway to work) The car only partly drops if I use the paddle which I can momentarily use when I start the car.

Have another look at the fault codes being stored for both the suspension ecu and the ABS ecu. You might have to get the codes retrieved using a different diagnostic tool if the nanocom isn't giving enough information.

The speed limit warning is only a warning to the driver, not an imposed limit.

Can nanocom do height sensor calibration ?

It can but I don't know what the hights are supposed to be. I can dump all the air out with the nanocom, but it is a pain in the ass to pump the air back in cause the system faults and stops me having access to the height paddle. I have to reset the code and continue to pump repeating those steps until its up high.

I remember reading in the nanocom book to take the height level numbers down and keep them in a safe place for this such event. I thought I will do that when I have a play with the suspension!

This may be a bum steer but the iidtool manual has the correct measures heights (is the vehicle at the right heights when inflated) and a calibration sheet to work from best sensor height to correct heights. Don't know if this would help or waste time but here it is http://www.gap-diagnostic.com/support/documents.html

I'm sure this is not a height sensor fault or calibration issue. A single out of range height sensor triggers an amber warning but more than 1 will trigger the suspension lowering to the bump-stops. Out of calibration only results in the vehicle leaning. With Llams off, is the "acceptable" height about access height or normal height? If about access height then its likely to be a brake system fault.

With the llams off, only the front seems to raise and drop while the rear stays at offroad or extended offroad. When I try to lower it, the front drops but the onscreen display says it's gone to extended offroad.

If the nanocom isn't showing specific suspension faults then you need to get it properly diagnosed otherwise you'll be guessing and stuffing around forever.

Been several months and several mechanics and still haven't found the issue. I've got it to a point now where I can drive it at normal height with an amber light on the dash. Every now and then, an error occurs and it starts dropping. I knock the car into neutral, turn it on and off, and then start it up again. The car pumps back up to normal height and I continue my journey.

Will be putting into the mechanics again shortly. Will let you all know how I go!

Is the warning light amber when the ignition is switched on but the engine not yet started or is it off but goes amber a few minutes after the engine is started?
