Diesel particulate filter (DPF) removal and DPF file removal.

What does the service involve ?

The Dpf removal service that we offer to vehicle owners, who wish to remove their diesel particulate filter (DPF), can save hundreds of euros. With average prices for a replacement DPF at around €1000, people are often looking for an alternative solution. The removal service includes the physical removal of the particle filter and dpf file removal from the ECU. This file must be removed to prevent the car from going into regeneration or limp mode. Once complete the car will perform to a much higher standard and will have absolutely no problem passing any NCT or other emmission based tests.

DPF Cleaning

Our DPF Filter Cleaning service is used on vehicles that have not yet shown symptons of DPF Problems.



DPF Regen

Our DPF Regeneration service is use on vehicles that have failed normal regeneration.



DPF Removal

Our DPF Removal service is use on vehicles that have blocked filters that are beyond there usable life.



DPF Replacement

Our DPF replacement service is used on vehicles that cannot have there DPF Removed.



How does a DPF Filter Work ?

DPF Filter Diesel Particulate Filter

 diesel particulate filter (or DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and under certain conditions can attain soot removal efficiencies of close to 100%. Some filters are single-use, intended for disposal and replacement once full of accumulated ash. Others are designed to burn off the accumulated particulate either passively through the use of a catalyst or by active means such as a fuel burner which heats the filter to soot combustion temperatures; engine programming to run when the filter is full in a manner that elevates exhaust temperature or produces high amounts of NOx to oxidize the accumulated ash, or through other methods. This is known as "filter regeneration". Cleaning is also required as part of periodic maintenance, and it must be done carefully to avoid damaging the filter. Failure of fuel injectors or turbochargers resulting in contamination of the filter with raw diesel or engine oil can also necessitate cleaning. The regeneration process occurs at road speeds higher than can generally be attained on city streets; vehicles driven exclusively at low speeds in urban traffic can require periodic trips at higher speeds to clean out the DPF. If the driver ignores the warning light and waits too long to operate the vehicle above 40 miles per hour (64 km/h), the DPF may not regenerate properly, and continued operation past that point may spoil the DPF completely so it must be replaced. Some newer diesel engines, namely those installed in combination vehicles, can also perform what is called a Parked Regeneration, where the engine increases RPM to around 1400 while parked, to increase the temperature of the exhaust.


Are there any legal requirements when removing a DPF?

There are no legal requirements when removing a DPF from your vehicle. After the complete DPF removal process (including the DPF-Tune software update)  your emissions will remain within the required levels as per your vehicle type which does not have a DPF.The diesel particulate filter on any vehicle is not a legal requirement, but often sold as an optional extra when the vehicle is purchased from new. As many people are seeking an alternative to replacing this expensive component when it breaks, MFK auto care provides the perfect option to saving pennies whilst increasing the overall performance of your vehicle.
