Where to start with sinking suspension?

The suspension on the D3 sinks down to access level after a few days. Initially it seemed to be more drivers side, but this is what it looks like after two days this weekend. I think there is an issue and it is probably getting a little worse.

Where do i start looking? It pumps up fine and maintains height if left whilst I am at work. Over night, it seems to go down on the driver side mainly and if left longer goes down as you can see in the pics below. The lab didnt really know what the problem was. The finger in the second photo was to block out the sun! But the D3 does look silly next to the D2 when it does this!!

you need to check which side goes down first. the car will self level that's why eventually it all goes down. if one side goes down start from that air suspension, spray soapy water to the line. then check the valve (rear or front), if the rear/front side goes down all together it means most likely that the relevant valve has a problem.
so basically investigate how it goes down, that will say a lot.

Will get on it when i get the 110 off of my ramp - currently on there with no gearbox attached!

I noticed today that i accidentally left one of the windows open for two days. Would this have made it worse by not letting it go to sleep or something? Interestingly the alarm didn't go off at all!
