Several Renault factories have been raided by Police, in what is thought to be part of a wider investigation into the VW emissions scandal.
The BBC reports that the company says fraud investigators wanted to check equipment at its factories, but stressed that tests have shown “no evidence” of devices designed to cheat emissions tests.
The company is also quoted as saying that Renault is fully co-operating with the investigation.
The BBC also reports that shares in Renault fell 20 per cent after the raids, with investors selling just in case the company may have cheated tests, which VW admitted to doing last September.
The shares have recovered some of those losses since then.
