It has been known for people to remove DPF filters themselves , but non-professional DPF replacement will almost certainly breach requirements under the Road Vehicles (Construction and Use) Regulations and the car will then be illegal for road use.
What happens if you remove the DPF filter?
However, DPF removal has both legal and social implications. The DPF filters need to be ‘regenerated’ regularly through burning the soot to gas at a very high temperature, leaving behind a residue. If not carried out properly, regeneration can lead to a build-up of soot, which can affect performance .
