Understanding DPF filter cleaning & regeneration
Accurate DPF filter diagnosis is crucial to identifying the best solution for the fault. Analysing vehicle mileage and other available diagnostic data can help determine whether the DPF requires a regeneration or removal and cleaning. Wherever possible, replacing a DPF filter should be a last resort, but this can often be the resolution if you don’t work with a supplier who is adept in diesel engines (like us!).
Understanding what is blocking your DPF requires experience. Soot and ash are commonly found in a DPF but as they are different materials, they need to be dealt with differently. Regeneration is typically used to remove soot, which is burnt by the process. For ash, as it’s incombustible, it can only be removed through professional cleaning of the DPF. We use a Flash Cleaning technology which is different to any other cleaning solution on the market as it allows us to clean all kinds of particulate filters and selective catalytic reduction units (SCR) used in cars (Euro 6 included), buses, trucks and plant vehicles.
