Diesel Vehicles: Exhaust Emissions
The question
To ask the Secretary of State for Transport, what steps she is taking to investigate the use of defeat devices in diesel vehicles.
Answered by Simon Lightwood
The Driver and Vehicle Standards Agency’s Market Surveillance Unit (MSU) is investigating cases of possible non-compliant diesel emissions in cars and vans. The investigations aim to ensure any non-compliance found is fixed as soon as reasonably possible, working together with manufacturers to achieve real-world impacts on air quality.
Where an investigation into the emissions has identified emissions that do not meet the required standard, the MSU will work with the manufacturer to implement improvement plans and, where necessary, recall affected vehicles.
