Transport Secretary Patrick McLoughlin told the BBC: "The Vehicle Certification Agency, the UK regulator, is working with vehicle manufacturers to ensure that this issue is not industry wide.
Opinion: why UK emissions inquiry doesn't make sense
"My priority is to protect the public as we go through the process of investigating what went wrong and what we can do to stop it happening again in the future."
The European Commission has also issued a statement, saying: "We invite all member states - in addition to the ones who are already doing so - to carry out all the necessary investigations. We need to have the full picture of whether and how many vehicles certified in the EU were fitted with defeat devices, which is banned by EU law."
The Society of Motor Manufacturers and Traders (SMMT) has previously sought to reassure UK car owners and issued a statement which said: “The UK automotive industry understands the concerns consumers may have following the actions of one manufacturer in regard to emissions testing and the subsequent decision to recall a large number of its cars. This is, however, an issue affecting just one company and there is no evidence to suggest that any other company is involved, let alone that this is an industry-wide issue.
“Consumers should be reassured that cars sold in the UK must comply with strict European laws. All cars must complete a standard emissions test, which, unlike in the US, is independently witnessed by a government-appointed independent agency."
