Is it possible to change from the standard (lowline) instrument cluster with the 4 warning bulbs in the center between the tach and speedometer to the highline version with the LCD display without getting into completely rewiring the car on a 96 A4 Quattro? I know I would need a new wiper stalk to get the buttons to change the center display, but other than that will it work with the existing wiring? Has anyone ever done this?
