The small screen in the middle of the Audi a4l dashboard shows the maintenance of aux.
Hello, owner, this shows that your vehicle needs maintenance and needs to go to 4s to change the oil. If the oil has been changed before, it means that the maintenance light has not returned to zero. You can call up the maintenance option through the CAR button on the multimedia display to see if you can manually reset to zero. If you can't operate, you can only go to 4s and use the computer to keep the lights at zero. No charge. I hope I can help you. Have a nice drive! If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
