Q7 2009 MMI Display issue
I do own and LOVE a Q7 2009, today when I started the car the MMI display turned on but it was kind of only gray, in a sense the backlight was on but it is just fully gray, I thought it might have to do with the warmer weather. But even after it cooled down all day and night in an underground parking it is still the same. All the MMI functions work, but the display is just gray. Any input here please ? Do I need to replace the screen ? The only thing I recall doing that was new is that I did use the iphone while connected to the music interface to listen to some Music through AUX.
P.S. I had the ABS pump replaced a week earlier, but I doubt this has anything to do with it.
