A diesel particulate filter (DPF) is a device which sits within a vehicle’s exhaust system and is designed to “capture” soot/diesel particles to reduce harmful emissions into our towns and cities.
It became legal for vehicle manufacturers to fit DPFs to all vehicles when “Euro 5” emissions standards came into force in 2009, although some VMs did fit them prior to 2009.
DPFs are intended to self-clean, through a process called “regeneration”. This happens under certain diving conditions and the particles are emitted, leaving only a small ash residue. Sensors in the DPF unit communicate with the vehicle’s central computer (ECU) to determine when to clean/regenerate the DPF.
For a wide variety of reasons, DPFs do not always regenerate when they should, usually due to driving style or conditions, or for technical reasons, such as a problem elsewhere in the engine.
As the DPF fills up and becomes more blocked, a warning light is shown on the dashboard.
If the problem is not addressed, the vehicle’s performance will deplete, the vehicle may go into “limp mode” and become unusable until the issue is resolved.
A standard diesel TerraClean service will help to remove particles from your DPF as part of a preventative maintenance programme.
But when the DPF is too blocked to allow air to flow through, a different approach is required.
There is a specific tool for DPF cleaning within the TerraClean range to remove the accumulated particles, and this service is available from almost all of our TerraClean service centres and mobile engineers.
So if you are considering having an expensive DPF Filter replaced give us a call to see if cleaning will be a cheaper quicker alternative, we cover all areas such as Leeds, York, Bradford, Harrogate, Wakefield, Sheffield and Doncaster for a TerraClean or DPF Diagnosis and Repair
