🔧 Q3 - Cabin Air Filter Replacement

Replacing your cabin air filter keeps dust, pollen, and odors out of the air you breathe and helps your A/C and heat airflow stay strong. On your Q3, the cabin filter sits behind the glove box, so the job is mostly careful trim and glove box removal.

Difficulty Level: Intermediate | Estimated Time: 0.5-1.0 hours

⚠️ Safety & Precautions

• ⚠️ Turn the ignition OFF and remove the key before working near the passenger-side dash.
• ⚠️ Support the glove box as you remove screws so it doesn’t drop and crack.
• ⚠️ Do not force plastic tabs; they can snap if cold. Warm the cabin first.
• ⚠️ Battery disconnect is not required for this job.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Clear the glove box area

• Open the glove box and remove everything inside.
• Use a small flashlight to locate the screws along the upper/inner edge.

Step 2: Remove the passenger-side end cap (side trim)

• Open the passenger door.
• Use a trim removal tool (plastic) (specialty) to gently pry off the side cover at the end of the dashboard (the piece you can only see with the door open).
• Pry near clips, not the middle.

Step 3: Remove the glove box screws

• Use a Torx T20 screwdriver and/or Torx T25 screwdriver to remove the screws around the glove box (typically along the top edge, lower edge, and the side area you just uncovered).
• Keep light upward support on the glove box with one hand while removing the last screws.

Step 4: Disconnect the glove box damper and any connectors

• On the right side of the glove box, locate the damper arm (a small piece that makes the glove box open slowly).
• Use a small pick tool (specialty) to gently pop the damper off its pin if needed. (A pick tool is a small hooked tool used to lift clips without breaking them.)
• If your glove box has a light connector, unplug it by pressing the tab and pulling straight out.

Step 5: Lower and remove the glove box

• Carefully pull the glove box straight back and down.
• Set it aside where it won’t get scratched.

Step 6: Open the cabin filter housing

• Behind where the glove box was, locate the cabin filter cover (a rectangular plastic cover on the HVAC box).
• Use a small flashlight to see the cover tabs.
• Release the tabs by hand; if tight, use the trim removal tool (plastic) (specialty) gently to help. Do not pry hard.

Step 7: Remove the old cabin filter

• Pull the filter straight out.
• Note the airflow direction arrow printed on the filter frame (you’ll match this on the new filter).
• Wear nitrile gloves—old filters can be dusty.

Step 8: Install the new cabin filter

• Slide the new cabin air filter into the housing in the same orientation as the old one.
• Make sure it seats fully and isn’t folded or pinched.

Step 9: Reinstall the cabin filter cover

• Press the cover on until all tabs click into place.
• Gently tug to confirm it’s locked.

Step 10: Reinstall the glove box

• Position the glove box back into place.
• Reconnect any electrical connector you unplugged (like the glove box light).
• Reconnect the damper arm to its pin.
• Start all screws by hand first, then tighten with a Torx T20 screwdriver or Torx T25 screwdriver.
• Torque to 2 Nm (18 in-lbs) for glove box screws. Snug only—don’t strip plastic.

Step 11: Reinstall the passenger-side end cap

• Line up the clips and press the cover back on by hand until it clicks.

✅ After Repair

• Start the engine and set the HVAC fan to medium-high.
• Check that airflow is strong and there are no whistling noises (a whistle can mean the filter cover isn’t fully clipped).
• Open/close the glove box to confirm it moves smoothly and the damper works.
