A Diesel Particulate Filter, sometimes called a DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. DPF's usually remove 85% or more of the soot.
In addition to collecting the particulate, a method must exist to clean the filter. Most filters are designed to burn off the accumulated soot through the use of active technology, such as a fuel burner which heats the filter to soot combustion temperatures, through engine modifications. The engine is set to run a certain specific way when the filter load reaches a pre-determined level, which will oxidize the particulates at relatively low temperatures. This is known as 'filter regeneration'.
The first indication of a fault is usually the EML (Engine Management Light) coming on.
If you have a problem with the DPF not regenerating, then the alternative may be a forced regeneration, much cheaper than replacement costs of anything up to £1000.
We have the necessary equipment and software to carry out these tasks at considerably less cost than DPF replacement.
