Ok, with an error, I managed to re-code the 431 options in FA and it is ok, an additional parameter I will try to test today.

[artur 1234]

I checked the codes in the rem module and I had all of them on activ, so I did not have to change anything there, unfortunately this switch does not work, I go the code in, FEM 3040 CLMICATOR_01 =
SMO_IND F> CLM_TIME_DELAY_BOOTLID = wert_02 is it one whole code?

Hello, can anyone advise you on how to code the above switch from the flap, unfortunately the above coding does not work, maybe someone has an idea what to change.

How was the wiring?
Were there 3 wires first?
Did you then retrofit the fourth wire to the FEM?

OK, I found my mistake.
Your car already has the option code 316 which contains the single button.
With option code 316 + 322 (comfort access) you get the double button.
So now we need the codings for the second button but not the codings for the comfort access.

Here from post #227 another guy already tried it.

Yes, I had one button and three wires, I made a connection fourth wire to FEM should I add 322 options? to VO

You could add the 322 and code the FEM and HKFM and the button should work.
But then you might get a lot of error messages because the 322 expects even more components.
The problem is to separate only the codings for the button, but I haven't been able to extract it yet.

Ok I understand, I will wait when I manage to get the necessary codes when you know something, write thanks for your help

I have another idea.
First, save the current configuration, so read out the CAFD from the HKFM + FEM and save it in a safe place.
You could now add the 322 to the VO and only code the HKFM.
If the button works, fine.
Now you can compare the CAFD (with 322) with the CAFD (readed out before, without 322) and possibly find out which value is responsible for the button.
If the values are not unique, you can also undo one value after the other to find out which value is responsible for the button.
If the button does not work after coding the HKFM, you can do the same with the FEM.
So code with 322 and if the button works, compare the individual values.

Ok i will do this encoding on saturday but i dont know how to write CAFD from HKFM itself?

Sorry, I don’t understand this question.

[artur 1234]

I do not know how to save these CAFD files and I do not know what to save and so be glad that you understand something because I write it all through a translator from Polish to English

OK, now understood.

When you read out the coding data with the "Read Coding Data" button, a file is created with the name CAFD _...... ncd.
This file is saved for each ecu in the folder C:/Data/CAF.
The FEM should then have the file name CAFD_00000794 _..._..._...ncd and the HKFM the file name CAFD_0000157F .... ncd or CAFD_00002098 ... ncd.
If you copy these files or all files from this folder (only copy, not cut!), then you have a backup of the current coding values.
You should actually always do this before coding something, because you can quickly restore the old coding status with it.
So read out coding data from the FEM and HKFM with "Read Coding Data", then save / copy the files from the folder C: / Data / CAF into another folder, then do the coding and then compare these files with those before the backup.

You can compare 2 CAFD ... ncd files by loading them into E-Sys in the FDL editor and saving them as FWL files.
So E-Sys -> Editors & Viewer _> FDL-Editor and load the CAFD / NCD and then at the top left "File" and "Save as FWL".
This FWL file can be loaded with a text editor and all coding values ​​can be viewed.
And some text editors (e.g. Notepad ++) can also load and compare 2 files at the same time.

Or the NCDCAFDTool can also directly compare 2 NCD files.

It is not on my head so much, I do not understand so much so I sincerely give up, i.e. tomorrow I will try to do it if I can, I will write or paste these files thanks for your help.
