Diesel Particulate Filter

Diesel engines have a Diesel Particulate Filter (DPF) which is designed to remove soot and other fine particles from the exhaust gases. The collected particles are eventually burned off in an automatic regeneration process. However, this regeneration process takes 5-10 MINUTES and requires the car to be at operating temperature while driving at highway speeds. Constant short trips tend to disrupt this process and lead to a blocked DPF.

A partially blocked DPF leads to harder engine starting, slight loss of power and lower fuel efficiency. An almost completely blocked DPF could force the engine into limp mode where power is cut and RPM is limited to approximately 2,500 in an attempt to reduce further damage.

At VW Village, we offer:
- Onboard Regenerations for partially blocked DPFs
- Bench Cleans. This involves the removal of the DPF for a chemical clean on a state of the art machine. We also conduct flow testing before and after to ensure the best possible clean has been performed.

If you are experiencing any signs of power loss or a drop in fuel efficiency, it’s time to bring your car in for an inspection.
