I think you may need to disable the idle stabilzer to really check this. I
have had no luck with the "pinch the hose test" either. The FI system
tries its damnedest to maintain the set idle speed.

These statements are inconsistent -- if it stays open you should get a
difference any time you pinch the hose.
Device may not close completely electrically (also, it will be expecting
around 13.5 volts) -- it depends partially on head from the head to close
it. Also make sure airflow is in correct direction, it only seals one way.
Note -- photos in Bosch FI book show one straight from the freezer, covered
in frost, with disk about half-plus open. Then they show one "warm" with
it almost closed.
