4. Remove the left and right plastic air-duct panels from the back of the engine-bay under the windscreen by undoing the plastic nuts with the arrow a 1/4 turn using a 13mm socket. The nuts are located one either side under the pollen-filter and one in the middle joining both panels.

5. Remove the strut-brace by undoing the bolt holding on either side holding it to the suspension turrets and the two in the middle using an E12 double-hex or star socket.
