To check the level of transmission oil in the motor box of the Aodi A4 3 generation, put the car on a smooth horizontal ground. Then we unplug the cork of the oil filler (located on the cardboard box). Using a suitable item (e.g. wire), determine the level of oil. For a box with a GYH index, the oil must be at the bottom of the hole. Other models have a normal level of 2-3 mm below the edge. If necessary, we can pour oil through the hole using a syringe. We're closing the jamming cork at 40 Nm.
