My MMI screen is blank, I have had the fuses checked and the cable is delivering power, so it would appear I need to replace the screen, I have found the part number (4G2.919.601.T or J or Q??) but these parts seem to be for the regular A6. Does anybody know if the screen from a regular A6 is compatable with the Allroad model as Allroad has the air suspension adjustment screen?? Any help gratefully received. Thanks
