Hi
The pollen filter is on the right hand side of the engine, you have to remove the the upper long plastic water diverter to get to it, if someone has recently changed the pollen filter check the water diverter has been refitted properly and the seal,s are good and that the drain hole,s are not blocked, because if it,s not fitted properly any water goes down the bulk head and end,s up in the footwell,s.
