Release the second plug on the air filter body
Now you can remove the pollen filter
Check the pollen filter for condition - replace if required
Now you need to remove the plastic undertray beneath the pollen filter
You will need a 13mm socket and a torx-25 to do this
Release this plastic moulding

...and remove the pollen filter undertray
You can now locate the brake fluid reservoir
Look for the MAX-MIN positions on the side of the translucent body
If the level needs topping up - WEARING GLOVES - carefully open the cap. Have a paper towel ready to catch any drips because brake fluid is corrosive
Now securely replace and tighten the cap
Now replace the pollen filter assembly
