After unsuccessfully trying the 100 second cranking protocol I ran codes again and this time I got code D1 (DME: Anti tampering protection EWS), which fits with
adrewwynn's thoughts. I was fortunate to find this earlier thread on that code:
https://xoutpost.com/bmw-sav-forums/...-no-start.html
But like others, my Foxwell NT510 Elite had trouble communicating, sometimes it wouldn't find the module, other times it would get halfway in and stop. I input the model manually to no avail and finally decided to try updating the Foxwell. That update has been running for hours but it says not to disturb it. In the meantime I saw this thread:
https://xoutpost.com/bmw-sav-forums/...ml#post1177584
Here
Redraptor141 explains that because of different build dates for the modules I may need to try inputting different build dates for my car. I will try that as soon as the Foxwell update is complete (if ever).
I also found
andrewwynn's explanation of how to test for spark solo ("To verify spark solo put paper between the electrode and ground it will burn a hole"). if the ECS reprogramming fails I will try that tomorrow.
And, belatedly, I have seen X5chemist's pots:

I have 2 diamond head keys. I have tried them both and just tried the manual lock/unlock, but no joy. I can try reinitializing them tomorrow.
Oddly I feel closer to a solution than I have in a week. Thanks to everyone for their help.
