Volkswagen has been accused of fitting illegal emission-cheating software to even larger engines in a new twist that brings Audi and Porsche deeper into the scandal.

The US Environmental Protection Agency (EPA) said 3-litre V6 diesels in 10,000 vehicles have been found to have 'defeat device' software. And there may be more as tests continue, it warned.

The Volkswagen Group disputes the claim and has offered to clarify and cooperate with any investigation.

But in a dramatic move, the EPA issued a new Notice of Violation to Volkswagen, Audi and Porsche. It claimed the software was capable of switching 'in exactly one second' from compliance with NOx emission levels when it detected official testing, to nine times the permitted limit under normal conditions. It said the offending vehicles with the V6 diesels included the 2014 VW Touareg, 2015 Porsche Cayenne and 2016 Audi A6 quattro, A7 quattro, A8, A8L and Q5 crossover.

If the EPA's findings are proven correct, it will drag Porsche and Audi deep into the emissions scandal which has already prompted a recall of 11 million vehicles worldwide over software fitted to 1.2-litre, 1.6-litre and 2-litre diesels.

It is not known if, or how many, 3-litre V6 diesels could be affected - in Europe or here.

Audi designed the V6 diesel for use in premium models sold by Volkswagen, Audi and Porsche since 2014.

However, the German carmaker insisted that no software to alter emissions characteristics was installed in those engines.
