Update 2 for today. Can not get that code to go away through any method but plugging the EHCII module back in. As soon as I do that everything is hunky dory. But my ride height LED's start blinking again and presumably my draw would return. My head is starting to hurt...
Here's what's going on:
INPA Error (reports same on Foxwell of course)
DXC module initially shows DXC8_E53.
C01 and then changes to DXC8_E53.
C04 as shown below. It will change after executing any job (coding or reading) but always reverts back to DXC8_E53.
C01 when I return. Is that normal?
Here's what the coding options for the module look like. Seems like everything is correct.

value_11 is for the correct engine and minus EHCII as shown in some of the other options. Oddly there is no option for N62B48 w/ EHCII. Only N62B44 and all the other E53 variants.
