In the middle of servicing my 2000 facelift 2.2CD.
Does air flow
UP (from large box with drain hole) or
DOWN (from grille at base of windscreen) as my new filter has arrow indicating air flow whereas the one I took out doesn't.
Would appreciate quick answer as I need to finish service soon as going on holiday tomorrow eve!
Apologies if answer is somewhere on forum but I've searched for over an hour with no success (even Haynes manual doesn't have answer)
Many thanks in advance

Tom
