E55 AMG Stiff Airmatic issue remains unsolved

So I had posted a while back about my stiff Airmatic issue here: https://mbworld.org/forums/w211-amg/903962-airmatic-ride-extremely-stiff-updates-but-no-solution.html

I had nowhere to go without Xentry so I went ahead and purchased a C4 clone as I am very sure this is an electrical issue. 2 months, one replacement laptop, and a $35 UPS “package from China fee” later I have it. I’ve been tinkering around and a lot of the menus are the same as my Launch scanner but there are of course many more options and tests. I am leaning towards some kind of CAN or central gateway issue. I see an engine CAN code (7211) and I noticed here on the interior CAN check that it says something about faults in the CAN communication but I’m unsure if I’m reading it correctly as there is no specified value there. If this is truly a fault, what can I check? If not, what else can I check on Xentry that can help me figure out where the communication issues are? I do have issues with water in the front area during heavy rain, I will sort out that and park under cover for now but I need to know what’s causing the Airmatic problems first. Any help is appreciated.
