The DVSA Market Surveillance Unit (MSU) conducts an annual emissions-testing programme to test vehicle emissions in the real world. Where MSU testing identifies non-compliant emissions, including suspicions of a prohibited defeat device, DVSA works with the manufacturer to implement improvement plans.<\/p>
<\/p>
The results of the MSU annual emissions-testing programme are made publicly available at https://www.gov.uk/government/collections/dvsa-vehicle-market-surveillance-unit<\/a>.<\/p> <\/p> Since 2015, there have been 134 manufacturer recalls or non-code actions involving a total of 1.85 million vehicles to amend or upgrade emissions systems. Not all action will have been to address non-compliance. A breakdown of the models by year is as follows:<\/p> <\/p>
