I have replaced the front drivers side wheel speed sensor with an OEM brand quality part. Cleaned out the hole and reinstalled.

I cleared all the codes in DIS and verified that the speed is indeed matching those of the other wheels when moving.

"Wheel Speed Sensor Air-Gap Excessive" still persists, this is cascading into my EHC2 and giving the trifecta error as well.

The wheel bearing and axle was replaced 3 yrs ago.

Any theories on the cause? ABS module or EHC2 module? I did have water ingress issues from the sunroof drain vents in the summer - but the system functions fine. If I clear the codes and do not move the vehicle, the air suspension system functions perfectly. I've rebuild the compressor and had no issues doing a leveling operation.
