T4 MKB Label File: Find AJT Label Files

hello,
I'm looking for a label file for a T4 TDI with the engine code AJT.
stg-nr is "074 906 018 B".
or is the label file 074 906 018 the same?

Sure, here is the translation of the text from German to English:

"Hello Leo_b"

Hello Leo,

Yes, generally speaking, the 074-906-018.lbl file is suitable for use with the AJT.
Depending on the distributor, there are different approaches to label files, and we are still working on improving this process internally.
It would be interesting if you could provide feedback on which label file you installed under what name, and how it worked.

It's difficult to provide installation instructions without knowing the file structure in your label file directory (since I don't know if you're a customer of mine, but that's not really important, or what version of the file structure you're using).

Generally, the following procedure is recommended for installation:
- If there is a redirection package, such as 07-01.lbl, then you should: a) create a label file for a typical engine control unit (ECU) class (for example, a file named 5-Zyl-VP-TDI.lbl; the filename is arbitrary, and the content would be the same as the 074-906-018.lbl file). b) create a redirect in the 07-01.lbl file for your specific ECU part number to point to this file. However, there should not be a file named 074-906-018.lbl in the label directory, because in this specific case, it would be used instead of the 07-01.lbl file (although the 07-01.lbl file can cover different ECU variants, which the 074-906-018.lbl file cannot: in the latter, 074-906-018-A and 074-906-018-B are treated as the same). Advantage: very well-maintainable label file structure; disadvantage: more work.
- Another option is to place a file named "074-906-018-B.lbl" in the label directory, where the file name corresponds to the complete ECU part number. Advantage: The file is easy to insert. Disadvantage: For each ECU variant (A, B, C, etc.), the file must be "copied," which makes maintenance very difficult.

That means that for someone who always works on the same car, the first approach is excessive, but it makes sense, for example, for me as a distributor or for people who work on many different vehicles.

Best regards, Rainer.
