Need help with Eurovan Secondary Air Injection - 17832 P1424

New to me 2001 AXK van. got it with skipped chain (intermediate sprocket teeth shaved right off). Also replaced headgasket and had head rebuilt. Put it all back together last night and it runs excellent! Issue is, while every other monitor sets fine, secondary injection fails after 10 seconds or so in Basic Settings group 231.

Here is the list of what I did so far:
tested solenoid: tested vacuum at solenoid when triggered and it pulls well. Tested a spare known-working solenoid - no change - fails exactly the same way.
tested air line to valve: no leaks no cracks, perfect flow
tested air injection valve: holds vacuum, doesn't allow back-flow when closed; switched to known-working valve - no change - fails exactly the same way.
engaged air pump with VCDS, while holding injection valve open with vacuum and felt the air at the exhaust.

This is driving me pretty crazy - I must be missing something simple. While testing, I hear the pump go on, the solenoid pulls vacuum, but VCDS shows no change at all, see pic:

Please help!!!

I have the same fault code you have/had. My SAI solenoid is always energized causing the combi valve to be open constantly. Did you ever figure it out?
