MOT rules tightened to detect missing DPFs

Government announces change to testing from February 2014

MOTs for diesel vehicles are to be tightened to ensure that DPFs fitted as standard are still present, The UK Government has announced.

From February 2014, garages and testing stations will be required to check for a DPF in the inspection of the exhaust system as part of the MOT. Vehicles will automatically fail if one is not present, where it should have been fitted as standard.

Roads Minister Robert Goodwill said: "I am very concerned that vehicles are being modified in a way that is clearly detrimental to people's health and undoes the hard work car manufacturers have taken to improve emissions standards. It has become apparent the government had to intervene to clarify the position on particulate filter removal given the unacceptable negative impact on air quality."

The news means the practice of removing DPFs for performance gains, or to bypass the cost of cleaning or repairing clogged filters, will be policed more thoroughly. Currently it is an offence to drive a vehicle if a DPF has been removed. The only way of checking prior to the tightening of the rules was through emissions testing, which was not a reliable method during MOTs.
