Follow these steps carefully
Open the hood on the B8.5 A5. The engine air filter box is on the passenger side of the engine bay. It is a large black plastic housing with an intake duct.
Release the metal clips around the airbox lid. On the B8.5 there are typically 4-6 clips. Lift the lid carefully without forcing it.
Lift out the old filter and note which way it faces. The filter has a rubber seal that must orient correctly. Compare old and new for size.
Wipe the inside of the airbox with a damp cloth. Place the new filter in the same orientation. Ensure the seal sits flat.
Close the lid and secure all clips. Verify the intake duct is connected. Start the engine and confirm smooth idle.
Take a short drive to confirm normal power. A clean filter restores throttle response on the turbo engine.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
