In almost 8 years on this forum I've never seen the valve body leak under the car.

Your front bags are new, the rears are original we suspect. Your compressor is new. We suspect the level sensors are original?

Read the codes it is throwing in the EHC module as you said the fault is on the dash. Report back to us.

I've also seen the module itself go bad, the part # that it was revised to ends in #999 I believe, its not a cheap part.

You have 3 items to check out:
-Rear bags (however you said after you ran the calibration routine it started sagging in the front and the rear holds air, which makes me think its ok)

-Leveling sensors (and the "linkages" that hold them on the control arm, they are $6-7 but are a ball/socket joint that sometimes seize up) - one level sensor in front and one in rear
-EHC2 control module (if needing to replace its about $600-700 and needs to be coded)

IF the error is on the dash, read the codes and post them.
