How often do you change a DPF on a Volkswagen passat?

The frequency of changing a Diesel Particulate Filter (DPF) on a Volkswagen Passat can vary based on driving habits and conditions. Generally, a DPF can last anywhere from 100,000 to 200,000 miles, but it may require cleaning or regeneration more frequently if the vehicle is used for short trips or idling often. Regular maintenance and monitoring of the DPF warning lights can help determine when service is needed. Always refer to the owner's manual for specific recommendations.
