I've read and reread so many posts and would just like a little advice.

Over night it goes lop sided, on start up sometimes it has a wriggle and levels up other times its a bong and Christmas tree dash board lights.

I can clear that with my OBD icarcraft reader, fault with K BUS error message.

I tried Craigs lift the wheel arch and listen for a hiss -no not that.

I put it into off road and left it over night as a double check for a leak, still up 10 hours later and level.
Drive off drop to normal height park up and less than 2 hours later it sits lop sided.
The selector still had red lights so I selected off road and up it went, drop back down to normal and it sits level.
Bit of a pfaff but works.

I've checked the height sensors are all connected and secure as should be. In the meantime I park in off road mode if I remember.

So the advice please. I guess it is the height sensor that is at fault and looks a dead easy replacement job. But when sitting lop sided it is front and rear so do both need replacing or what?

From a logical point of view if you aren’t getting a leak when it’s in off road height then the bags are probably OK. If you have a secure drive then try it in normal mode with the door open. That should prevent it changing height that way you can see if it’s data from the sensors, turn insde lights off tho so as not to flatten the battery.

Does you tool let you see live data from the sensors. It may be advisable to get it plugged in and get a view of what sensor is doing what. You will then be able to see which one is giving eroneous info and save having to replace both.  There is nothing that can't be fixed with a hammer😜😜

Weather and health prevented me from having further investigation until yesterday. I found the front down both sides and will not budge. Tried driving and it's a no. Eventually got some height and could drive to collect my grandson. Got home and as my grandson got out he said the car is hissing so I have a leak. Not sure if that is the cause or a further development.
It is now nose down and no way can any of my jacks get under it I unable to check for any quick fix.
I hope my breakdown recovery can take me to Cam Tech.

I did notice that sensor front nearside is showing 47 volts! The other 3 around 3 volts.

Craig at Cam Tech gave me excellent help over the phone - thought I'd mention it.

Cam Tech Craig sorted me out, hole in bag after all.

Top job by a top bloke what more can I say.

Not keen on LR parts prices though.

Thank you sir...

Appreciate the business
