Furthermore, live values for the shocks show no real issue. Im not sure what my next step should be other than to bring it to the dealer. Any advice for diagnosing this concern.
110 currently has 26k mi. P400.
when you say the codes seem unrelated? What codes are in it? Im wondering if the gap tool is not reading the relevant codes.

With the tool, can you clear each modules codes individually, or can you only clear all the codes

I can clear individual codes and i can clear all at the same time. I can also flash ecus and see that an update is available for the CHCM. How can I determine whether this is hardware or software?

Try waiting until the symptom happens then clear the air suspension control unit faults 1st. See if the symptom goes away.

Its currently in what seems like the hardest setting and clearing faults doesn't really remedy it.

Interesting. So u stated in the previous post that when you clear all the failts in the vehicle, the hard symptom goes away? Is it now always faulted?

[ My 110's suspension is rock hard And has been for 5k miles or so ]
And you still drive it ???

( If I put my EAS in the highest LLams setting then it is rock hard, you don't want to drive that a above 15 mls/h, very dangerous)

Hope you solve it to drive in comfort again.

Yeah despite clearing, suspension is still jarring. I have been waiting for a new dealership to open. This one is 10 min away -- way closer than glen cove (90 min). This is a bizarre problem and seems software related. If i were out of warranty i would remove the eas/magneride dampers in favor of springs and bilstein dampers
