The current test has been amended over recent years to introduce lower emission limits. The removal of after treatment devices, such as diesel particulate filters and selective catalytic reduction devices, have been added to the list of reasons why a vehicle would fail its MOT.<\/p>

In May 2018, the opacity limits for diesel vehicles will be tightened for newer diesel vehicles.<\/p>

The Department for Transport undertook real-world emissions testing of Euro 5 and 6 diesel cars and the results were published in the Vehicle Emissions Testing report in April 2016. Further real-world emissions testing of other vehicle types is being undertaken by the Market Surveillance Unit and will be published later this year. Additionally, the government has been at the forefront of calls for the introduction of tougher emissions testing at a European level and the new Real Driving Emissions tests will come into force for all new car models from September this year.<\/p>
