I didn't turn the orange light off, I told the car it didn't have have the orange light. Not sure if you mean the same thing by saying you turned it off.
I selected the option "driving profile button without function light" i.e. telling the car that there is no orange light, which immediately turned the orange light off as I have the car in individual mode & this is lit with key turned in ignition (engine off).
However even after exiting vcds etc. & with engine on, pressing the button did not bring up the driver profile menu in the infotainment screen which it should still do.
So the tweak does not work properly...I also tried a soft reset of the infotainment unit & that made no difference either..
So back to how to turn the orange light off without totally disabling the button.....
