instrument cluster lighting VCDS tweak

Hello,

i have a skoda octavia mk3 and the lighting for the instrument cluster (rev counter/ speedo) is the weirdest thing i have ever seen.

I already change dimming_characteristic_curve_adjustment_clock_dail_day-x1 through x6 to 64 so the lighting is on when its a clear day. 

I still have the cluster going dark if i pass a big tree or something. 

Does anyone know if it is possible to make the lighting never go fully dark. Maybe go dim to 30% if you don't turn your lights on?
