Definitely worth the email. I bet the manufacturers get hundreds of similar requests every day, so producing the documents must be an almost automated process, not by individual interpretation. It does look like VW are using the emissions data, not the build code. Good luck.

It depends entirely on who you contact. Here's an earlier reply from Germany:

Dear Mr. Brown,
Thank you very much for your email.
You would like your Volkswagen Lupo with the above-mentioned chassis number to be recoded
to a different emissions stage.
Vehicles with the emission level Euro Norm 3 do not technically meet the criteria of Euro Norm
4. Therefore, a recoding is generally not possible. A corresponding retrofit solution (hardware or
software) is not available.
Please ask the AUDI Kundenbetreung about the mentioned Audi.
