Hi fellow enthusiasts

.
So, the person mentioned above (from Ireland) has daytime running lights that are constantly on, and they really don't like how the control elements of the xenon headlights work.
So, none of the suggestions helped. Maybe someone else has an idea.
I couldn't find anything about the country code.
Turn off the light switch - The plug might have 15 wires, but there's no connection between them.
Where should I look? Or should I use Vag?
According to VAG-COM:
...
{On-board network}
ECU coding.
Select STG 09 (On-board network).
STG Long Coding -> Function 07.
"But this control unit is not responding - I guess it's probably not available..."
Thank you in advance.
