No it's not, parking on a slope provides load on each wheel, a four or two post lift does not... I think there is some sort of gyroscope in the vehicle that provides the positioning information to the suspension system....

I drove mine up my standard car ramps after getting back from Rockingham, to wash the underside and re fit the front tow hook cover. They are normal ramps about 10 inches high. No errors though.

It may even be something to do with the airtools when te nuts are undone. Ijust have tofind out. I know the dealer just accepts it as normal now.

'normal' ramps, which support all wheels will not induce spurious errors, two or four post lifts that support vehicles purely on their chassis legs will, by virtue of there being no load on the suspension components - hence theneed to drive them after being worked on - what I need to understand / identify is how a wheel change, where only one wheel is raised, is identified as such

Wishful thinking!
PM me yer email, and I will send you the schematic of the air pumping bits. The levelling is very simple and is controlled by four sensors, one on each wheel, which is a simple height/tilt switch. All it does is keep the vehicle level, based on input from these. It is far simpler than it may initially appear!
Think I will try parking the front wheels in the Matbro bucket in the morning, then lift the whole thing up and see what messages I get.

Yep, that I can understand, but the ramps my car has been on support the axle, so no rise or fall of the suspension is done.

Thats because the sensor is pushed to the limit, and the level at which it guesses, as a result of input from the other sensors, that the vehicle is about to ground; it then goes into extended mode.

Axles or wheels? Well, not axles, as we don't have them any longer, but raised on the suspension arms, wheels akimbo?

No on the underneath of the part where the air bins are supported.

On the trailing arms, then.
I think that might confuse the beast. However, it is dark and raining here. I will look in the morning.
I bet, though, that raising the vehicle from the underside of the tyres will not create the same error. What I need to check is how the height sensor is attached.
If the suspension arm doesn't move, but the wheel/sensor does, then that explains why an error is reported. Its not a real error though.

On schematic, 5319 is the compressor assembly, 3137B is the receiver valve assembly and 3137A & C are the front and rear valve assemblies respectively.
5B740A is just the plastic cover.

Oh, and 5637E is the main air intake........

There wouldn't be a tilt sensor on the car for the suspension would there to tell it when it is level?

There's one at each corner, but nothing gyroscopic or central.
The suspension is calibrated with the vehicle level, after that all the suspension does is work to keep the body level (or levelish as you go round corners).
