How to Change the Headlamp on an Audi A4

1. Check your manual for the specific model number of your Audi A4. Go to your local auto store and pick up a replacement headlamp which is the correct make for your vehicle.
2. Locate the mounting bolts for the headlamp on the front bumper. Use a socket wrench to remove the bolts. Ensure you don't lose any of the bolts as you will need to reattach them later.
3. Pull the headlamp away from the light casing. Use a flat-head screwdriver to pry it out of its socket and disconnect the battery connector.
4. Unscrew the two screws on the headlamp to gain access to the bulb. Unclip or unscrew the bulb depending on the model of headlamp. Insert the new bulb, ensuring it is firmly locked in place.
5. Reattach the headlamp to the Audi A4 following the removal steps in reverse. Turn on the vehicle's engine and engage the headlamps to ensure they are now working correctly.
