DPF Filter Removal

Diesel particulate filters (DPFs) are designed to trap harmful soot particles from diesel exhaust gases. However, they can sometimes become clogged or damaged, which can lead to a number of problems, including reduced engine performance, increased emissions, and even a check engine light.

If your DPF is not functioning properly, you may be considering having it removed. However, it is important to be aware that removing a DPF without the proper modifications can make your vehicle illegal to drive.

The Process of DPF Removal

The process of DPF removal involves removing the filter from the exhaust system and then gutting it. This means removing the ceramic honeycomb filter element, which is what traps the soot particles. Once the filter element is removed, the case is then welded back together.

How to Pass Your MOT After DPF Removal

In order to pass your MOT after DPF removal, you will need to have the vehicle’s engine control unit (ECU) reprogrammed. This will tell the ECU that the DPF is no longer present and that the vehicle does not need to undergo the regeneration process.

The Benefits of DPF Removal

There are a number of benefits to having your DPF removed. These include:

  • Improved engine performance
  • Increased fuel economy
  • Reduced emissions
  • No more check engine light

The Risks of DPF Removal

There are also some risks associated with having your DPF removed. These include:

  • Increased exhaust emissions
  • Increased risk of engine damage
  • Possible legal issues


DPF removal is a complex process that should only be performed by a qualified technician. If you are considering having your DPF removed, be sure to weigh the risks and benefits carefully before making a decision.
