If, on the above mentioned vehicles, there are complaints about a degradation in the function of the heater blower motor or air-conditioning blower motor and a reduced air flow is also apparent in the vehicle interior, the pollen filter is a possible cause of the problem.

As a rectification measure fit the modified pollen filter.
