DIESEL PARTICULATE FILTER INFORMATION
The price is for the part only and does not include any fitting costs.
Topgear / Longlife has a number of depots throughout the country who are able to provide a fitting service for which they will be able to quote you.
Topgear / Longlife is also able to offer a DPF removal service at many of our depots in conjunction with an engine remap.
Removal of your DPF will give an increase in engine power and fuel efficiency and have the added benefit that you will not have to worry about replacing the DPF again.
There is no current requirement to have a DPF on your vehicle so this service won’t affect your MOT.
Unlike a Catalytic Converter, a DPF is not a flow through device and works by forcing the gasses to flow through the filter.
As the channels of the filter are blocked as alternate ends, the gasses are forced to flow through the cell walls in order to exit the filter.
As the cell walls are porous, the gasses are allowed to pass through, but the particulate matter is deposited on the cell walls.
This ensures that only the clean exhaust gasses can exit, and the particulate matter is trapped in the filter.
DPFs need to be regularly maintained to prevent a build up of soot in the filter.
Effectively they are a ‘soot trap’, so in order to prevent it becoming blocked and affecting the running of the vehicle, it has to be cleaned.
This is done with either the use of passive regeneration or active regeneration.
A warning light on the dash will warn the vehicle owner is the DPF is becoming blocked and regeneration is needed.
Passive Regeneration - occurs on long journeys when the exhaust temperature is high and the soot burns off naturally.
For vehicles which unfortunately don't get this kind of use, Active Regeneration is needed.
Active Regeneration - occurs when the level of soot in the filter reaches around 45%.
The ECU makes small adjustments to the fuel injection timing and increases the exhaust gas temperature.
This increases the exhaust temperature which then initiates the regeneration process, burning away the soot trapped in the DPF.
Some types of vehicle (especially Citroen and Peugeot models) use a fuel additive to aid the regeneration process.
The fuel additive is added to the fuel tank every time the vehicle is filled with fuel.
It is common in vehicles where there isn't enough room to locate the DPF close to the engine where the exhaust gasses are hottest.
The fuel additive lowers the temperature at which the soot particles trapped in the filter ignite and burn off.
This allows regeneration to take place at a lower temperature than normal.
