Technical Injector code confusion
Did you managed to program new injector (0445110520) using MES?

Did you managed to program new injector (0445110520) using MES?It seems that 0445110418 and 0445110520 injectors are mechanically compatible, but they use different IMA Bosch Coding for the correction codes. Either bench test report needs to be done and new IMA code generated or... there is some guy which can decode/encode BOSCH codes, so they shall be able to transcode the IMA code according to the injector model: https://mhhauto.com/Thread-Free-injector-IMA-correction-code-calculation-decoder?page=21
I guess it's all about: "this is reserved for professionals only, give us your $$$", as there doesn't seem to be reason to change the coding convention every new release.
Gonna give it a go, as I don't expect much from my Chinese seller, even though I politely asked

What model does this reffer to? Have you tried yourself even with simulate mode. if it is refusing to code it maybe you are using the wrong model designation. If you cant get it to work and believe it should then contact Yanni the developer.
I saw you tried programming the injector using MES and it completed, but it still didn't change. Looking at your photo of the injector, do you remember what symbol you have used for 6th symbol when trying to code the injector? Was it 0 (number) or O (letter)? I tried it on my MES and it seems that I can't use 0 (number), only numbers 1-9.
Either way, the last symbol is what worries me. Original injectors end in "F", but new ones does not, and you can't even put the last symbol in MES. Maybe it expects "F" so it doesn't ask for the last symbol, but then it would result in incorrect coding.
It's for X290 Ducato. Asked Bosch directly regarding 0445110418 and they said it was discontinued and replaced by 0445110520.
I don't think this is meant to work since this is wrong model designation issue.
Yes, because these codes doesn't seem to be compatible with each other. Different encodings.
It was probably letter O, since you can see that zero is written differently with the diagonal, but that doesn't matter, since in the end that code wasn't accepted.
0445110520 replaced 0445110418, for newer models, likely with a newer ECU... so you either need to get 0445110418 injectors (they're still sold), or decode 0445110520 values and encode it in 0445110418 format (there are some paid apps on Android and online website, IMU coding it's called).
The other alternative is to get your injectors sent to people with Bosch testing machine, they would be able to test injectors on the bench and print-out the values as if it was the 0445110418 injector.
Final option, not recommended is simply to ignore it. It works on my end, but it might not work on your end. These codes are meant to provide initial injector calibration data to the ECU. If difference between what you have in the ECU (old injector values) and what you have in practice (new injector) too big theoretically engine damage could occur.
Regardless, if you manage to find a solution. please let us know, I would be keen to program it properly on my end.
