That’s an interesting theory..I guess the thing is how do you know whether it’s normal or whether there is a leak or not? Would a warning light come on? I can’t find any examples of L405 suspension leaks online. Plenty of L322 issues found and I wondered whether any weaknesses have been addressed. 2017 Range Rover Vogue V6 Diesel

I really wouldn't worry about it, pretty normal with air suspension cars... My 5.0SC does it, but so did our AMG GLC43 and our AMG GLS63. They all have a mind of their own... |

Certainly no light that I am aware of on the 322. I completely removed the front suspension valve block numerous times, which technically completely deflates the front bags, and not once do I recall any warning lights on startup again, just the suspension raising back to normal, honestly doubt the 405 would be any different. Even when the 322 bags eventually called it a day and ruptured I had no warning lights, only loud hissing.. I used to park the 322 outside at night, have moved since which is why the 405 now has the luxury of sleeping inside, I did note that the 322 would drop more over winter months than summer.. Granted, our winters are not as bad as yours, maybe get to -1 at night, but then days warm up to around 18-20 (celcius), but cold again at night, and she would drop more... You are in winter now, maybe the warm / cold scenario I describe previously does have an effect, but apart from the suspension settling by virtue of the vehicle electronic brains every so often, unless she dips significantly, I really would not worry about this, sincerely.. consider Bl4ckD0g's comment above and accept they all move a little from time to time.. edit - its a little after 4am here, just got up to start the day so I thought let me check, started the 405 up up, around 10 seconds in she popped first the nose and then the backside up around 1cm, lets call it just shy of half inch, and settled in that beautiful V8 SC purr that only the 405's give... Put her back to sleep for a few more hours.. Then I got to think about our state of emergency Covid19 lockdown in March this year, I had parked her and disconnected the battery, and left her like that untouched for 2 odd months. When I eventually got to use her again, reconnected the power and as expected she started up just fine and lifted just ever so slightly, nothing excessive considering she was dead for +60 days, where had there been a leak causing the overnight dip, by day 60 she would have been resting on her belly if she could.. |

The air springs are now covered, at least the front ones are - in my opinion this is a major upgrade, as the L322 I owned had at least 4 or 5 punctures because of rocks/metal/glass caught in the air spring fold... Always in the front ones. Concerning the self levelling, it is almost non existent compared to the previous Range Rover, that used to adjust several times a day... Now, it is true that in the beginning the air system used to make a sudden thud every now and then, mostly when started, which was kind of scary, as it was in the rear area and I kept thinking I hit something... This was solved in a software upgrade at some time. |

My 2018 13k mile does the same adjustments first thing whilst parked on the flat, only half an inch correction or so may be more.. it is the first time I’ve noticed it, none of the other 4 L405’s ever did this. Did wonder whether to mention it on next service.
