How to Replace a Xenon Bulb in a 2001 Audi S4
- 1). Open the hood and remove both T25 Torx screws found at the top of the headlights. This is done from outside of the vehicle.
- 2). Loosen the two T25 Torx screws found on each side of the headlights. To get a better reach of the screws, attach an extension to the screwdriver.
- 3). Pull out the headlights and press the metal clips behind them in order to detach the headlights from the wiring.
- 4). Pull out the turn signal bulbs at the sides of the headlight units.
- 5). Pull out the headlight back covers and press the metals clips behind the bulbs to unplug the wiring. Slide out the xenon and high beam bulbs using a cloth to prevent them from getting smeared with oil from your skin.
- 6). Repeat the steps in reverse with the new xenon bulbs.
