2012 LR4 Reluctant to lower from off-road suspension mode

[jackkyxu]

may I ask what is a normal working status for the compressor?


should it run every time car is ignited or every day to top off the reservoir (like very short duration of working)?



sometimes when I turn off the engine and lock the car, I can see car lowered immediately , sometime I do not see, is it normal?

As I mentioned in the other post, mine runs shortly after cold start and then as needed. The car will level itself every two hours when not running (which is why there are threads when diagnosing overnight dropping issues that talk about removing the fuse in the engine bay). Other than this the compressor will run when the reservoir gets below a certain pressure; not sure what that pressure is but I'm guessing it's in this forum somewhere (and also possibly in this thread as I know I charted some pressures in the past).
