DPF Removal

BMW DPF Removal / Mini DPF Removal

A potato stuck in your exhaust!

Diesel particulate filters restrict exhaust free flow and once they are blocked, it becomes like having a potato stuck up the tailpipe!

If DPF Removal is your preference we can provide the complete process or just the ECU software modifications.


DPF Removal is not recommended by Dragon Automotive and completion of any works relating to this process is subject to a disclaimer contract.

DPF Removal for BMW and Mini

An Alternative Solution

We are able to offer a complete DPF removal package for all BMW and Mini DPF Filters.
There are a number of pitfalls to this, most notably is that the vehicle will no longer be compliant with EU4 or later emissions regulations.

After a DPF removal you will benefit from:-
Better MPG
Better Performance
Increased BHP

You will not be able to tell visually that the DPF has been removed, nor will a standard MOT test be able to detect an increase in NOX or Soot Emissions.

The Complete Bypass Process

The complete DPF Removal procedure involves:-
Physical Bypass Process
Software Modification
Oil Flush
Test Drive & Quality Control

The physical bypass is subtley done by opening the housing on a seam and reclosing with an inconspicuous weld. The software modifications involve remapping the existing software for the removal of the filter. An oil flush is performed as there is usually oil contamination when a DPF has been blocked, this is precautionary for best practice. Before returning your car to you, the technician will test drive the vehicle to check that the performance is faultless following the bypass procedure. A supervisor will then carry out quality control before the customer service agents are advised of the vehicles job completion.

DPF Removal Complete Package from £350.

DPF Remap Process

When a DPF bypass is done the vehicle software needs to be modified for the filter no longer being present. It has been known to do this by deleting large chunks of the error code tables so that no fault codes can be triggered. Unfortunately this also affects other systems. We do the remap properly.
It takes time and is complex to achieve but there is no deletion of error codes involved.

We offer a software only package whereby you carry out the physical removal of the filter yourself elsewhere and we only perform the software modifications. We also offer a software combi package whereby we perform a performance or economy remap at the same time at the dpf remap for a discounted price to having them done separately.

DPF Removal Software Package from £250.
DPF Removal Software Combi Package from £300.

Does Removing a DPF Increase Emissions?

Removing a DPF filter will increase Soot and Particle Emissions

However, because you gain MPG benefits you are burning less fuel.

Therefore, Carbon Dixoide Emissions will be lower
