07 cls550 rear airmatic slow sag over night.

I have an 07 cls550 and randomly a few weeks ago the driver rear would lose air after about 5-8 hours of sitting. And then 2 weeks later the passenger rear. When I open the door it fills right back up to normal and some days it doesn't even drop. I replaced the air comroessor just because it has 116k so I might as well but it still does it. but No errors on dash either. My question is how can I go about checking for leaks in the system and where. I read about the central resoirvoir and the valve block. I don't know where that is.

It's obvious that you have a leak in the system,but where,and how to find and how to fix---use the expensive WAG or WTFK system----or get smart and find someone with DAS who in minutes will find the fault(s)!!

I do know someone with the star. But will it tell me if a specific individual strut is leaking or just a general leak in the system?
