Is it legal to remove the DPF from a diesel car?
I've seen adverts for companies that can disconnect the diesel particulate filter from the car's ECU. Is this legal and does it make the car better? I think you said only in the last couple of years DPF have been compulsory on new cars so presumably on an older car it would be ok?

It would have to be removed altogether or would just clog up and removal of DPFs make a car subject to failure in the new, more stringent MoT rules that came into effect on 1 January. Removing a DPF alters the cars emissions on which it is taxed so could even be construed by HMRC as tax evasion, if they had the time.
