Be careful not to lose any of the screws, as you will need them to reattach the assembly later.

Step 2: Disconnect the Wiring Harness

After you have removed the screws, gently pull the tail light assembly away from the car. You will then need to disconnect the wiring harness that connects the assembly to the car's electrical system. To do this, simply push down on the clip that holds the harness in place and pull the harness away from the assembly.

Step 3: Remove the Bulb Holder

Once you have disconnected the wiring harness, you will need to remove the bulb holder from the assembly. To do this, twist the bulb holder counterclockwise until it comes loose from the assembly. Be gentle when doing this, as you don't want to break the bulb holder or the assembly itself.

Step 4: Remove the Old Bulb

With the bulb holder removed, you can now access the old bulb. To remove the old bulb, simply push down on it and turn it counterclockwise until it comes loose. Be sure to dispose of the old bulb properly, as it may be hot or contain hazardous materials.

Step 6: Reattach the Bulb Holder

With the new bulb in place, it's time to reattach the bulb holder to the tail light assembly. To do this, simply twist the holder clockwise until it clicks into place.

Step 7: Reconnect the Wiring Harness

Once the bulb holder is in place, you can reconnect the wiring harness to the assembly. Simply push the harness back into place until you hear it click into place.

Step 8: Reattach the Tail Light Assembly

With the new bulb installed and the wiring harness reconnected, it's time to reattach the tail light assembly to the car. To do this, line up the assembly with the mounting holes and insert the screws that you removed earlier. Be sure to tighten the screws securely, but not so tight that you strip the threads.

Step 9: Test the New Bulb

Now that the tail light assembly is back in place, it's time to test the new bulb. Turn on your headlights and make sure that the new bulb is working properly.

Step 10: Clean Up

Finally, clean up any tools or materials that you used during the process and dispose of the old bulb properly. Congratulations! You have successfully replaced the tail light bulb in your 2004 Audi A4.
