It's done!!!!
Bought LR023651 and installed it and then the calibration went through without any problems. I can now raise and lower the car without any problems and it no longer goes into extended mode.
I would like to thank everyone...
That part number is for 2002-2009 MY, which as you're finding out, is different to production year. To be fair, the seller shouldn't be saying it's valid for any L322 production year. Other sellers list it from the year the part was introduced...
No you don't - you can also tell you don't as there are only 3 wires connected to the height sensor, on the L322 the sensor has two separate circuits in it, one for the suspension & one for the ARC system so you would have 6 wires connected if...
Yep, the 9A & AA are different, which may explain the odd behaviour when swapping pins around. The plug is mechanically the same between versions of sensor and the pins will be in the same configuration.
The sensor is the same part number for 09MY & 10MY https://parts.jaguarlandroverclassic.com/parts/index/part/id/17.52080.52122.35795/brand/land-rover/ LR020627
Edit: oddly, if you look at the 10MY (vin year identifier starts AA) it's different...
According to the circuit diagram, the wiring was done correctly. The old plug had the same correct wiring. What I noticed is. In the gap tool my Range Rover is shown as a 2010 model even though it is a 2009. But the plug is for 2005-2009 models...
I'm glad you said that! I've got a graph showing expected voltages vs. height somewhere, I'll see if I can find it! You've also got me thinking if the cause is in fact a rear sensor if both sides are tracking equally...
Yes, I've already tried it. The sensor is recognized but no longer shows altitude values. The height value is always the same even when I jump around on the page.
That's very odd - have you tried swapping the +5V & the 0V lines over? I know you say it's wired correctly, if nothing else, it'll eliminate it as a possible cause.
Hello! There is another update: The new height sensor arrived today and I installed it straight away. Same problem again. Funnily enough, I realized this during the calibration: If I raise or lower the car during calibration, the numbers change...
Maybe it is the sensor, maybe its the wiring🤷♂️.
Do you still have the old sensor? how does the new and old compare?
But I have dug for what I have. Note the difference in years.

Only the ) volt and +5 volt wires can be swapped, the third wire has to be on the correct pin or there will be no change in the values as the arm moves.
This may sound silly, But.
The hard plastic rod down to the suspension arm, the ends are rubber(ish) is the arm fully pushed in?

Do you still have your old sensor?
Hello. The arm is definitely easier to move than the old one. I turned the arm 360 degrees with the motor running and suddenly I was in the range below 250 and I could save. The problem was that when I restarted, the old 366 value was there...
This thread may help - it seems the IID doesn't always play nicely with ARC / EAS systems

I don't use IID myself so I can't really be any more help with the error code other...
