Suspension fault after jacking up

Hi guys, jacked up my tdv8 to change diff transfer and engine oils, opened doors and when I’ve dropped it it’s sating front left corner is too low.
The car looks level, what does the sensor look like? Could I have knocked it?

Cheers

If you have not already done so: Start then run for a few minutes and then move the suspension level switch a few times or go for a slow drive. This sorted mine out after a similar issue. The car is confused!! Then height sensor is a square black box with an arm off it attached to the lower suspension arm with a wire off it. Have a look here to see. https://m.ebay.co.uk/itm/Range-Rover-L322-...1898540167

Thanks, I’ve driven it a few miles now low and high speed, selected low and off road height, it all works as it should it’s just showing as front left low still. Parked and gone back to it, still the same.
Do I need to recalibrate it?
If so I’ll be needing diagnostic tool, what one is recommended, I’d like to do as much as poss with it. 2010 3.6 tdv8

Check the height sensor on bad corner. They get brittle and the arm to the bracket can snap.. you can temp fix it with a cable tie until you get a new one

When you say " showing" is that on the 4x4 infotainment screen or the car actually looks low at one corner. I have never had to re-calibrate my suspension even after jacking up many times on a trolley jack or on a two poster lift or after fitting a new front levelling unit. The tool most people seem to prefer is the GAP llD BT. Look on the forum, it will do most of what you will never need to do. I have a Foxwell NT510 does most things but not everything the IID tool does.

On the 4x4 screen yes, the corner seems at the right height.
I’ll have to get under there again and check the sensor. If it’s snapped would the corner go up or down ?
I’ll look at that gap tool nice one.

If the sensor arm is broken it could show either. Just depends on where it was positioned when it broke, but they do more quite easily.

Check the plug on the sensor too. Mine came loose when it was in the landrover garage and they then listed it as a fault until i told them to check again as it was fine when i brought it in and they realised it had come loose. Car was fine but one side showed low on the 4x4 screen. Current 2007 TDV8 Vogue Buckingham Blue

If car will raise when it’s started then pull the fuse to the air suspension.. this will stop it self levelling.. if you have a bad bag then it will be evident on that corner

Found oil on the sensor, must’ve spilt some somehow. Is it worth stripping and cleaning or is it futile?

I believe that they are a sealed unit as they are open to the elements 24/7.
