S320
Airmatic problem - where to check now?
I had the two left-hand side struts on my S320 fail. The two on the right-hand side were still working properly.
After replacing the two defective struts I now have the weirdest problem. Both struts on the left-hand side are still failing, all the way down. But now also the right-hand side rear strut, which worked perfectly before, has failed and dropped.
The compressor functions fine, I can still lower and raise the right-hand side front strut, but the other three don't seem to get any air.
Do I need to reset the ECU or can I check something else?

Yes.
While there are many possible causes for your problem, one is a broken intake hose on the compressor. The air inlet hose should run from the compressor to a small inline filter, then up into a hole in the chassis. This routing prevents entry of dust and water. If this thin rubber hose splits, both dust and water can enter the compressor and air system. Not only will this wear the compressor piston ring and cylinder, but the mud can cause corrosion and sticking valves in the valve block that sends air to and from the struts.
