Dont think the developers got it wrong, they are using the commands they can and it has worked on many cars.
Pure guess on my part but maybe we should be looking at Leuchte12NL and Leuchte 13NL settings as this i think is the command set for the fogs
update - just checked old mk3
coding
1 - Module 09 - Electronic control unit - Code (31347)
2 - Adaptation
3 - Leuchte12NL LB45
4 - Lichtfunktion E12 - (Change value to Tagfahrlicht)
5 - Dimmwert EF 12 - (Change value to 60 for example so that it does not illuminate too much)
6 - Dimming Direction EF 12 - (Change value to Maximize)
7 - Leuchte13NL RB5
8 - Lichtfunktion E13 - (Change value to Tagfahrlicht)
9 - Dimmwert EF 13 - (Change value to 60 for example so that it does not illuminate too much)
10 - Dimming Direction EF 13 - (Change value to Maximize)
Tagfahrlicht meaning Daytime running lights so worth a check if this is how its setup
