Diesel Particulate Filter Removal

Evolution Chips Exhaust Gas Recirculation (EGR) Valve Deletion

Haynes Vehicle Services is pleased to be an approved installer for Evolution Chips. If you answer yes to any of the below questions, then please contact us about Diesel Particulate Filter Removal.

  • Are you having problems with your Diesel Particulate Filter?
  • Are you facing some very expensive repairs?
  • Are you sick of the extremely poor MPG your vehicle returns whilst the DPF is regenerating?
  • Do you want to remove the troublesome DPF form your vehicle altogether?

We can alter the software in your ECU so that your DPF can be safely and properly removed from the vehicle without logging any error codes. We do this process properly and stop the ECU trying to regenerate in the future.

Benefits of diesel particulate filter removal are:-

  • Better Performance
  • Increased MPG
  • Avoid Expensive Repair Costs

What is a DPF?

A diesel particulate filter (or DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.


Most vehicles fitted with a DPF will need to have it replaced at some point as part of the service schedule, if it has not already become overloaded in the meantime. This can be very expensive.

Is the DPF required?

The Diesel particulate filter is not currently a legal requirement, nor is it currently needed for the yearly MOT test so the most cost effective solution is to have someone actually remove the DPF from the exhaust system. (Ideally using a replacement section, so that you can refit if ever required, such as at resale time or to satisfy any changes to future MOT legislation)
Once that is done, we can help you by deactivating the various functions within the ECU.


The DPF captures soot off the exhaust when you are driving. This is generated by particles which are produced during the combustion of the fuel/air mix. As the saturation levels get higher, the particles turn to ash which in turn must be processed by the filter. In order to do this, the filter must regenerate to remove this accumulation of ash. However, due to various engine problems or alternatively the end of life of the filter, it may become blocked and the filter eventually replaced in order to prevent failure or engine damage.
