HWH Active Air issue - left front cycling up and down while air leveled

[J&JD]

I did lube the o-ring on my new solenoid prior to assembly. Unfortunately the new solenoid didn’t solve my problem. So, I’m back trying to find the leak at the right airbag or the myriad of lines leading to it. Two Freightliner shops + an independent were not able to locate a leak, sigh.
