Modern Diesel Mazda’s come with a DPF integrated into the exhaust, and it is in place to trap and remove Diesel Particulate Matter or soot from the diesel exhaust gasses before they are released into the atmosphere. The process allows 80% of diesel particulate emissions to be removed, however, even with this process in place, when the DPF burns off this soot via regeneration, an ash residue is left in the DPF which cannot be burnt off, and the build up of this is what causes the DPF to become blocked. Once this occurs, it is no longer possible for the regeneration process of the filter cleaning itself to be carried out.
The following reasons may also contribute to premature blockage of the DPF filter, which include:
These issues can go on to create further problems as mentioned above which include loss of power and when these problems are not dealt with immediately, they can go on to create further damage to other components. A prime example is when the pressure begins to build up in the exhaust due to trapped gasses, they try to escape from the next weakest point which in this case will be either the turbocharger or the EGR valve, causing damage eventually to these components.
As mentioned above, the regeneration process is a vital part of the DPF running efficiently. It usually occurs whilst driving in optimum conditions which will occur on a 15-20 mile motorway journey at 40-50mph. Those that drive a Mazda in the city, however, will find it a lot harder to carry out this regeneration process at the optimum conditions, which can go on to cause the DPF to get blocked a lot quicker.
Some of the following symptoms are signs of a blocked DPF filter on your Mazda:
These faults can cost in the region on £1000+ to repair if not dealt with as soon as possible. We have had customers that have come in the past advising us that their garage has advised that replacing the vehicle would probably be more cost effective as the repairs cost so much! Therefore, we always advise that DPF’s are dealt with immediately to prevent any further damage to your car.

Also, along with the above-listed benefits, the turbocharger and engine will no longer feel any strain or pressure which will allow them to work more efficiently with improved power. With the Regeneration process cancelled out, the lifespan of the injectors is also increased as they are no longer required to squirt diesel at longer durations during the regeneration cycles.
Will DPF Removal Cause Me To Fail An MOT?
From February 2014, the law is changing to include the visual inspection of the Diesel Particulate Filter (DPF) during your MOT inspection. Although our DPF Removals are very discreet and our smoke-correction ensures the vehicle won’t smoke come MOT time, we are offering our DPF Removal sessions as an “Off-Road Use Only” service.
