First, I believe it to be fairly common for the truck to sag a bit after years. Mine moves a bit once I start it, compressor fires right up and auto levels a degree or two. Especially with the 145lb bumper on the front. Unless the compressor is running all the time, I think your momentary compressor and leveling is fairly normal. My neighbors 2013 LR4 does the same thing since his driveway is angled.
Start simple in troubleshooting before you go into bigger things. If you do not have FACTORY LR TAIL LIGHT BULBS, get them ASAP and replace all bulbs in your tail lights. They are cheap compared to what expenses you may be ready to step into now so nothing is lost by verifying and replacing these if needed. I didn't find this problem until my first real offroad trip in Hawaii. I was up in the mountains and the truck was taking quite a jossling and all of a sudden my suspension dropped, HDC fail, sensor fail, ABS fault, all kinds of stuff. Of course I ran all over for like an hour on how to get my truck fixed in safe mode and then as I sat on the trail, noticed my tail light was out again. Since I was stuck for the moment, why not replace it right?. Put a spare bulb in that I had in the glovebox, turned the truck on to check it and when I closed the door to walk back and check it, the truck raised up and all was well. This exact same thing happened a week or so later, only when I looked at the tail lights, they all lit up with no issue so I wrote off the tail light issue. I replaced the brake light switch with NO success. Then I found a thread about the impedence sensitivity of the LR electrical system relating to tail lights. Since I was out of options, getting ready to pull suspension sensors and all, my box of replacement LR lights from AB showed up. I pulled all four bulbs, replaced the Silvania Oreilly aftermarket lights with LR and boom, all was fixed and have not had a problem since.
Point is.....if you do not know what lights you have in, check them and get LR in there even if the aftermarket appear to be okay. I have helped save a few people on the island thousands of dollars from my lucky chance experience I learned from others. One guy was selling his wife's LR3 advertised as suspension needs a new ECU according to the dealer. I texted him, told him to check his tail lights and sure enough, same issue. He's still driving it today with a light bulb fix that LR quoted him thousands of dollars for a EAS module and couldn't be happier. He was selling because he couldn't justify the repair costs added to the hundreds he already stuck into failed diagnostics fees.
Second, many members said check the wheel well wiring. Get it cleaned up nice and start with pulling connectors, cleaning inside with electrical cleaner, corrosion cleaner, etc... and then dielectric grease. Start with the height sensors if you wish for piece of mind, then the rear wheel wells which are of common failure. I do not think its a height sensor or steering angle sensor as I showed the same issues along with many different codes. I do think its related to minor electrical fault and a good cleaning and look over will ensure you connectors are good, your lights are good and maybe see a broken or frayed wire as you inspect.
Hope anything here helps you out. I was in the same boat and ready to rip out expensive parts only to find it was an easy fix with a bit of tedious cleaning and inspection.......which in my opinion is the norm with our LR3 and rarely to we see catastrophic failure of major parts without indications of failure first.
