Disco 2 suspension sleeping

Hi,

Can someone help me pls. I have a Disco 2 V8 02 plate. When the vehicle is not used for a couple of days (sometimes) the rear (nearside) suspension drops. As soon as I start if up it self levels ok again.

Has anyone got any ideas please, I have also attached a pic.

Not sure if suspension or self levelling.

thanks for your help.
