Sometimes the screen in the instrument cluster ( not the main touch screen) will flicker under certain circumstances. For example if the wipers are running, and the car is i park it will flicker. Turn the wipers off and flickering stops. Any thoughts, is this normal ? I verified it while driving the flickering is definitely occurring only when the wipers are running. 2010 XF Supercharged. Issue goes away after driving for a while and engine is warmed up.
