A pollen filter can be found in every modern car, this was not the case in the days of our classic car. But there was a predecessor of the pollen filter, the air supply was filtered through a kind of grid against all kinds of flying insects and debris.
It is recommended that this grille be cleaned at every service so that the air supply also remains fresh and does not pass by a bunch of dead insects entering the interior.
These plastic grilles do not last a full Volkswagen car life, there comes a time when just cleaning is no longer sufficient, cracks and tears will make you replace the grille.
