2011 E350 Wagon rear suspension dropping
Hi folks, I have a problem with the rear suspension dropping when parked. This starts with the passenger side dropping then the driver side drops to match it, this started as an intermittent problem when it was cold, then it done it more frequently when it was warm, finally we took it to a repair shop that done the following work:
1. Replaced passenger suspension airbag - Did not fix issue, seemed to make it worse
2. Replaced with 2nd airbag as mechanic thought new airbag was bad. - Did not fix issue.
3. Leak checked all lines - No leaks found
4. Replaced valve between compressor and suspension. - Did not fix issue. - Car now drops about 1/2" in 30 minutes starting with passenger side.
5. Mechanic said he put a vacuum on system and smoke checked it and found no leaks, not to familiar with a smoke check.
Does anyone have any recommendations on where to go next? Is it worth changing lines or is there some other test that should be done on this? Is there a method to cap all lines pressurise and make sure they dont leak? Is this possibly as simple as a calibration?
I appreciate help on this frustrating issue

I just got a quote to replace my compressor for around $1500 from an independent MB shop! Both rear suspensions were dropped and not raising when I started. I've looked online for a DIY fix but haven't seen anything. Any resolution with yours?
