The Pollen filter for the Musa is located behind/below the glove box. Not the top one but the one at the front, without a door. You have to remove 4 torque screws . 3 are located inside the upper top roof of glove compartment and the final one is located right underneath, near the pillar/bottem. The Panel comes away in one, including part of the side panel near the gearstick. Also for everyones information : lots of fuses are also behind this panel.
Nearly forgot :inside, you have to unclip a flap like pillar box shaped panel to remove the pollen filter, easy to see and easy to remove. Total time to complete everything 7 minutes. ( That was in the dark and raining!)
