A blocked DPF (Diesel Particulate Filter) cannot clear itself completely. Driving at highway speeds can help initiate a process called regeneration, where the accumulated soot is burned off, but severe blockages usually require professional cleaning. Regular maintenance and using low-ash engine oil can prevent such blockages.

FAQs & Answers

  1. What causes a DPF to become blocked? A DPF can become blocked due to insufficient regeneration, using high-ash engine oils, or frequent short trips.
  2. How often should a DPF be cleaned? It is recommended to check your DPF based on manufacturer guidelines or if you notice warning lights indicating blockage.
  3. Can I drive with a blocked DPF? It's not advisable to continue driving with a blocked DPF as it can lead to engine performance issues and damage.
