The most significant risk posed by a Volkswagen car with an air filter problem is reduced engine performance. The air filter is responsible for trapping airborne particles like dirt, dust, and other debris that could otherwise enter the engine and cause significant damage. If the air filter is not functioning properly, these particles can enter the engine, resulting in decreased performance, increased fuel consumption, a decrease in power, and general engine wear and tear. Ultimately, this can lead to costly repairs and reduce the car’s resale value. In order to prevent these issues, it’s important to have the air filter inspected and replaced on a regular basis.
