Has anyone had any issues on their light switch unit failing? Switch on my 2012 a7 is throwing a code saying circuit malfunction terminal 58s which the internet tells me that relates to the lighting control for exterior light function.

This is the unit in question.

From what i can see, maybe the button illumination or illumination brightest knob is the issue. Hard to see its functioning during the day this time of year ill check it out tonight when it gets dark.
