Valve block or something else?

My EAS appeared to drop overnight. I checked it out by pulling fuse F26, measuring the vehicle height in the evening and then again the next morning. I did the test twice; once at offroad height and the second time at standard height. My findings were at:

Offroad height: front drops by 10mm on each side, back drops by 3mm on each side
Standard height: front drops by 16mm on each side, back drops by 7mm on each side

So I probably have a leak somewhere.

Can anyone advise on where to begin?

Thanks.

clean out the front value block.

It will have white dust inside. Take apart wash out with water. (there are video's on youtube)

It's quite easy to loose the seals, so if you can get them where you are I would recommend you replace them too

Many thanks Pete K.

I also suspected the front valve block.

Out of curiosity, why would the rear of the car also go down if only the front is dodgy?

Rear has got a smaller leak.
But it’s a nightmare to change the rear block, so I would just start with the front and see how it goes.
