Sinking Air Suspension

Soon after purchasing my D3 I noticed that the suspension was sinking over a day, then overnight, then within 9 hours.
Yesterday evening i removed fuse 26 and took measurements at 18:00
NSF 805mm OSF 803mm
NSR 835mm OSR 860mm
This morning I was hoping to see one corner, or either the front or rear had sunk, what Ive seen has surprised and worried me
NSF 760mm ie dropped 45mm OSF 760mm ie dropped 43mm
NSR 750mm ie dropped 85mm OSR 780mm ie dropped 80mm
So all corners have dropped, rear more than front. If I leave this another 24 hours I assume it will settle on the stops which it has done if left for 2 days.
There are no suspension warnings or faults showing on the dash.
I was hoping that this was going to be the front valve block but now this looks more daunting. Any advice / help appreciated.

A friend's D3 and my Range Rover have both suffered a similar fault. Mine was a tiny hole in the pipe across the rear crossmember. Get it on a ramp and check the pipework. Mine was a £4 repair and a slab of beer for a mate's ramp for an hour.

The D3 was a touch more serious and one corner bag was leaking. Replaced with parts off a well known auction site for less than £100 and all ok now.

No faults on the dash or the code reader so it's back to a manual check Thumbs Up
 D4 HSE....Probably, but not quite decided yet.

Half an hour with a squirty bottle of soapy water will do it. Get it up to off-road height, and spray every airbag, pipe and valve.
