Does anybody know if this is 'normal'?

We left the 'Beast' for maybe 12 days without moving it and when we came home on Friday evening, a couple of corners looked like they belonged in deepest L.A.

On start up and shutting the door, all returned to normal. Had a little play and all heights/setting working and responding just fine.

So, as above, is this normal? (2012 Autobiography.)

Thanks in advance.....

I don't have this on my 2012 car yet, but when my 2004 car was a bit older it happened from time to time. It didn't seem to matter, one just had to give the compressor a bit of time to get the car back level following starting it. Only Range Rovers since 1988

Well this isn't the first post that I've read that concerns a late L322 being parked up for a number of days and sinking It can be a bit alarming when it's your new toy, but it's a Range Rover.... they get the hump and sulk if you ignore them for a while As long as you didn't get any suspension in active messages, I wouldn't worry too much, just think of it that the car missed you  Yesterday I couldn't spell Engineer...

(Possibly) Completely normal. 12 days and locked (no opening doors, etc) on a flat surface should see the RR somewhat lower but not necessarily on the bump stops. They self-level at regular intervals while parked, and since the compressor will not run w/o the alternator (engine) running, they can only go down. If you were parked on an uneven surface, opened and closed doors regularly (increasing the self-leveling frequency), or any one of another number of reasons could cause this. You could also have a leak or your calibration could be marginal. But I would not fret.
