🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Create access behind the headlight

• Put on safety glasses and nitrile gloves.
• If a plastic cover/air guide blocks your hand behind the headlight, remove its push-pins using a trim clip removal tool.
• If there are small bolts holding the cover/duct, remove them using an 8mm socket, 1/4" drive ratchet, and 1/4" drive extension 6".
• Set the fasteners aside where they won’t fall into the engine bay.

Step 2: Locate the front turn signal bulb socket

• From behind the headlight, find the bulb socket that goes into the headlight housing (it’s a round plastic “twist-lock” piece with wiring attached).
• Use a flashlight to confirm you’re on the turn signal socket (not the low beam/high beam).
• If it won’t move, don’t force it.

Step 3: Remove the bulb socket

• Grip the socket firmly by hand (use nitrile gloves for grip).
• Twist the socket counterclockwise about a quarter turn, then pull it straight out.

Step 4: Replace the bulb

• Pull the old bulb straight out of the socket (or twist and pull if your socket uses a twist-in style).
• Install the new front turn signal bulb (amber) into the socket.
• Do not touch the bulb glass—use nitrile gloves.

Step 5: Reinstall the socket

• Insert the socket back into the headlight housing.
• Twist clockwise to lock it in place (it should feel snug and fully seated).

Step 6: Reinstall any covers/ducts you removed

• Reinstall bolts using an 8mm socket, 1/4" drive ratchet, and 1/4" drive extension 6".
• Reinstall push-pins using a trim clip removal tool and gentle hand pressure.
• Torque to 5 Nm (44 in-lbs) for small 8mm plastic/cover fasteners. Snug, not tight.

Step 7: Repeat on the other side

• Perform the same steps for the opposite front turn signal bulb.

✅ After Repair

• Start the A4? No—on your Renegade, turn the ignition to ON (engine off is fine).
• Test left and right turn signals and hazard lights.
• Walk around the vehicle to confirm both front signals are bright and the same color.
• If a bulb doesn’t work, remove the socket and re-seat the bulb, then re-test.
