What is the issue if your car cannot be read at BMW on their computer/diag machine?

JB4 interferes with coding. I usually can live with it if it's on map0 but in two extreme cases it had to be taken off.
Edit: now that I remember both times it was on N55. One Procede and one JB4.
No issues that I can recall on N54.
