The DPF filter reduces particulates by 20% and while it is not illegal for a garage to move it it is illegal for a driver to drive with it removed. Curious! Curious! However, the MOT is being strengthened in 2018, and new all diesel vehicles will have to have a DPF fitted from 2018.
Aftermarket DPF cleaning additives Effectiveness of DPF cleaning additives. Several aftermarket DPF cleaning additives claim to help clean the filter without removal by breaking down soot particles and aiding in their combustion. Some drivers have reported success with these products, while others have found them ineffective or harmful.The particulate filter is used to capture and reduce the amount of harmful soot particles emitted from vehicles. These are mainly found in diesel vehicles. The particle filter is designed to catch soot particles inside.
