Suspension let down

[ianbollans]

Hi
Just purchased a Disco II. The rear air suspension goes down when the vehicle has been parked, but only when weight is put onto the back. It goes down to the stops within about 30 seconds. When started again the suspension pumps up fine. The dealer can find no leaks. If left overnight it's fine and it stays level. It's only when weight is applied.
Any thoughts would be welcome!

Welcome aboard - this is the place to ask questions like that. I can't answer it, but there's dozens of blokes (and a few girls) who can and doubtless will. They scare me.

Stick the car in its highest suspension setting,then spray something like wd40 over the air springs,watch for small bubbles on them. They seem to go porus but only leak under certain circumstances-like where they are parked etc.If you cant id any leaks then the only other 2 possibilites are the valve block or the air harness. Please dont rush to replace any of these components-be absolutley sure where the leak is.The air springs are the usual suspects !:(

Both air springs replaced and holds up a treat!!!
