Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will seek assurances from Volkswagen that software and technical fixes made in response to problems with emissions testing will not change engine output, fuel consumption and performance data.

The UK’s Vehicle Certification Agency issued the type approval for some Volkswagen Group vehicles. For these the agency is working with the manufacturer to review and approve the proposed fixes. They are carrying out tests to ensure that after the fix is applied the vehicles meet all the legal requirements including emissions, and that other vehicle characteristics are unchanged, including power output, fuel consumption and engine noise.
