DPF is short jargon for “Diesel Particulate Filter” a sort of catalytic convertor for diesel cars. Many owners of diesel cars. Hence, here in the UK. Of course, have them removed. The DPFs are also cut open with cutting gear. So all the insides are removed and then the DPF is welded back up.

It is an offence, under the Road Vehicles Regulations to use a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet.

Heavy fines for removing this from your car could be as much as £1000 or £4000 for a van owner. The Department of Transport, are looking for of developing a machine for testing the cars with a DPF fitted. Of course, at the moment the regulations only say that a visual examination is required.
