I have no idea on the BMW stuff, but from memory the EDC16 Bosch stuff can run injector coding, so there is a good chance that because they are not set right the ECU isn't happy, despite the injectors technically being mechanically ok and working to a certain degree.
The starting might literally be to do with injector differences, the map for injection calibration is very finely set around starting/idling conditions and even a slight change to values might mean it won't do the start-up sequence, yet while in running operation the values can deviate more and more and still give you a running car.
So there are two issues, the injector calibration may be out enough to stop start-up sequence working, and the coding might be also causing issues, or might just be making the warning light appear and nothing more.
Someone with experience with these two cars should know really.
Why not just get some injectors designed for your car (EU3) and see if it will start despite the coding still being wrong?
If so then you know the issue is injector calibration and the coding is almost irrelevant...
Mini rant, but why even code injectors? What is the code any way, and mini calibration table? Or is it just some kind of feature to try stop theft of parts or something?
Hmmm
