Diesel Particulate Filter (DPF) Solutions
What is a DPF for?

The DPF collects soot (the black smoke from diesel cars) while the car is running. At some point then the DPF is full and needs to be cleaned. So at that time an automated regeneration process will begin to automatically clean it but only if certain parameters are met.

By removing the DPF correctly, you save your car from working overtime to clean the DPF and you benefit from increased fuel economy.
