DPD and DPF Explained

Every vehicle manufacturer calls their emissions control system something different, DPD (or Diesel Particulate Diffuser) or DPF (Diesel Particulate Filter), but ultimately they all work the same way and achieve the same result. Put simply it’s a filter for your exhaust!

When your equipment senses that this filter is blocked it engages a number of functions to raise the exhaust temperature to over 600*C in order to clear it. This process is commonly known as a “regeneration” or “burn”.

This process sounds relatively simple but it involves many different systems all working together and is actually quite complex. If one of these systems fails you will be stuck on the side of the road in “limp” mode, which means costly downtime.

At MRDS we specialize in the maintenance and repair of most major OEM emission control systems.

  • Periodical half or two hour regenerations
  • Breakdown assistance for vehicles stuck in “limp” mode
  • Diagnosis and repair of DPD faults
  • The latest software and scan tooling for all major OEM’s

As we are learning more about climate change there is a stronger emphasis to reduce the amount of emissions produced by diesel engines. While these systems are often not popular with vehicle owners, the fact is that they are here to stay and are only going to become more and more prevalent in the future.
