I just checked the FP and FN ECUs and they do in fact have BB chips. And I check the KR EC, but I'm going to guess it has a BB chip as well.
Well, now it fits again. I really doubt that there are ME7 shipped with 800BT originally on the board.
Hmm. Then I need to look elsewhere for why my 4B0906018DA -> 06A906032FN flashed but did not work (no communication).
Thanks,

I can now explain why the 4B0906018DA -> 06A906032FN can't work, it was quite obvious
but I was on the wrong track due to this BB <-> BT discussion.
The reason is just a bootrom version mismatch. There exist two different bootrom
main version for ME7.5, 05.xx and 06.xx (at least I did not see more up to today).
These two are NOT compatible. An application (flash image) build for version 06.XX can NOT
run on an ECU with bootrom version 05.XX embedded in the C167, and vice versa!
For ME7.1 only 05.XX seems to be used, so there this problem should never happen.
If you look at the information of me7check, you'll see the problem:

Conclusion is: if you want to use ME7.5 images of different ecus, you have to keep in mind
that there are two different sw streams which can't be interchanged.
