Diesel particulate filter (DPF) problems

Diesel particulate filters (DPFs) are designed to trap soot particles from diesel engines. However, DPFs can become clogged with soot over time, which can lead to a loss of power and increased fuel consumption. This is often caused by short journeys or driving in stop-start traffic, as the DPF does not have enough time to regenerate and burn off the soot.

  • DPF regeneration: DPFs regenerate by burning off the soot that has been trapped. This process usually occurs automatically when the engine is running at high speeds for an extended period of time. However, if the engine is not run at high speeds for long enough, the DPF will not be able to regenerate and the soot will continue to build up.
  • Short journeys: Short journeys are a major contributor to DPF problems. This is because the engine does not have enough time to reach the high temperatures needed for regeneration. As a result, the soot builds up in the DPF and eventually clogs it.
  • Stop-start traffic: Stop-start traffic is another major contributor to DPF problems. This is because the engine is constantly stopping and starting, which prevents it from reaching the high temperatures needed for regeneration. As a result, the soot builds up in the DPF and eventually clogs it.
  • Implications for VW T6 Transporter vans: DPF problems are a common issue for VW T6 Transporter vans. This is because the T6 is often used for short journeys and driving in stop-start traffic. As a result, T6 owners are more likely to experience DPF problems than owners of other vehicles.
