How do I Change the Headlights on a 2002 Audi A6?
- 1). Pop the hood of the Audi and remove both T25 screws on top of the Audi's headlights, with a T25 Torx driver.
- 2). Loosen but do not remove the two T25 screws located at the sides of the headlights using your Torx driver. Connect the T25 driver with an extension piece to access the screws.
- 3). Slide out the Audi's headlights and pull the metal clips found at the back of the headlights to detach the wiring and to completely detach the headlights from the Audi.
- 4). Repeat the steps in reverse with the new headlights.
