Discovery 3 sinking suspension

[Discovery2008]

Have read several views in diagnosing this problem - my 2008 discovery 3 sinks by several cm when left overnight. Non main LR dealer could not diagnose the problem.

Over the course of 7 hours the car would sink:

front right 1cm. Front left 1 cm
Rear right 2cm. Rear left 0cm


I have now tried disconnecting the battery to see what happens and the car did not sink at all in the course of 10 hours.

Can somebody help with this - valve block, compressor, electronic problem, airbag?

Thanks

If the battery is diconnected and it doesnt drop at all, it seems there is no leak. (im not an expert). the car does "wake up" every once and a while and self levels by lowering certain corners. Im not sure how often it does this, but maybe its normal. Is it parked on uneven surface? Im sure others will chime in.
