🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Access the passenger-side filter area

• Open the front passenger door and look under the glovebox area.
• Use the trim panel removal tool to gently pry off the lower passenger-side access cover or trim panel, if equipped.
• If your Tiguan has retaining screws, remove them with the T20 Torx screwdriver.

Step 2: Remove the cabin filter cover

• Locate the rectangular cabin filter cover behind the lower dash area.
• Use your fingers or the trim panel removal tool to release the cover tabs.
• Pull the cover straight down or outward, depending on how the tabs are oriented.

Step 3: Remove the old filter

• Slide the old filter out slowly so debris does not fall into the housing.
• Use a flashlight to inspect the filter box for leaves or dirt.
• Vacuum the housing if needed.

Step 4: Install the new filter

• Compare the new filter to the old one to confirm size and shape.
• Check the airflow arrow on the filter and install it in the same direction as the old one.
• Slide the new filter into the housing until it seats fully.

Step 5: Reinstall the cover and trim

• Reinstall the filter cover and make sure all tabs lock in place.
• If you removed screws, reinstall them with the T20 Torx screwdriver.
• Snap the lower trim panel back into place by hand.
