A3 8L 1.8t 2001
After installing ColorMFA, the LCD screen of the meter now shows that the passenger door of the front seat is always on and cannot be eliminated.
It is normal before replacing the ColorMFA LCD screen. It is normal to determine the function of the door lock block. What causes this condition to occur?
There was no gray instrument plug on the original car. In order to install the S3 meter, the gray plug was added. At present, only the 17/18/19 pin is connected to control the multi-function wiper switch.
