Airmatic sucks?

I was driving down the freeway and my car ( 2015 c400 4matic) malfunctioned and dropped both the front bags to the ground and after sitting for a couple weeks the rear also dropped. I followed lines no leaks, visually no holes or crack in bags. They are newer anyways within the last two years. Compressor still functioning. I was able to jack the car up and fill the front two struts with air but when sat back down it falls back to the ground. I am thinking valve block or the airmatic control module. Any tips help. I don’t want to convert to coilovers but also trying to fix myself.

You would probably be well served to look through the S Class (W221 / W222) forums for airmatic diagnostics.
