J'ai trouvé ca sur un site anglais, pense tu que ça soit pour avoir l’éclairage du tableau de bord tout le temps allumé ? Qu'en pense tu ?
The dashboard lighting—including the infotainment screen—responds to changes in ambient light levels. You may have noticed a brief ray of sun on a cloudy day, for example, causing everything on the dash to get brighter. (You can also test this by shining a light on the sensor. The sensor is in the tach, between the "7" and "8".)
The instrument cluster dials, however, behave differently, especially on MY2016 vehicles.
With the headlight switch in the "off" position, the cluster dims to black when it is dark. This is to remind the driver to turn on the headlights.
Somewhere around MY2016, this "off when dark" cluster dimming behaviour also made its way to the "parking light" (or "side light") position in some markets. While I understand this can help inattentive drivers, I've found a few situations where I would've liked cluster illumination without the main beam.
Many thanks to JonboyGTD on another forum for this VCDS tweak. It allows cluster illumination with the headlight switch in the "parking light" or "side light" position:

[Adaptation-10] > Change (1)-Illumination_algorithm-Scale_switching_algorithm from parking_light to lds
Now, my cluster is fully illuminated for all headlight switch positions except OFF. The cluster still follows the "on until dark" dimming curve in the OFF position, and is still responsive to changes in ambient light.
