Bonnet up -the filter is between the back of the engine bay and base of the screen, passenger side. See the plastic moulding with rubbery flap? Lift the forward edge of this flap and the filter is visible. The filter is held in by 2 plastic clips which need to be unclipped and folded back to allow the filter to come out. Put the new filter in, and close the rubber flap, adjusting it to give a good seal. Job done!
