If your Volkswagen vehicle has a cabin filter problem, you could be at risk for some potentially dangerous issues. The cabin filter is responsible for cleaning the air that comes into the vehicle from outside, and when it is not functioning correctly, the air quality inside the car can become significantly deteriorated. This can lead to poor visibility, an inability to properly focus on the road, and even the development of respiratory issues. Additionally, the cabin filter can become clogged if not maintained, which can cause the air conditioning to not work as efficiently, and can potentially cause the blower motor to overheat and fail. Lastly, a clogged cabin filter can lead to an accumulation of mildew, mold, and bacteria, which can lead to a host of allergic reactions and illnesses.
