Up to 80,000 Irish cars may be affected by the Volkswagen global emissions-rigging scandal, based on the number of new Audi, Seat, Skoda and Volkswagen cars sold here between 2009 and 2014.
The company is expected to reveal after a board meeting later today which models are among the 11 million involved in the scandal, in which millions of its diesel vehicles worldwide were fitted with software to trick emissions tests.
German officials believe VW has manipulated tests in Europe as well as the USA. The Tánaiste Joan Burton sais there was likely to be an investigation here.
Meanwhile a new Volkswagen CEO will be appointed today after the company's former CEO Martin Winterkorn (pictured) resigned. Three more executives are facing the sack.
Jim Holder from the What Car website said the scandal should not entirely onscure that VW has been making huge and genuine progress with its diesel engines in recent years.
"There's no question the manufacturers have been trying to maximise their results in the tests, but I don't think what's happened this week should lead us to overlook the massive strides they've made in fuel efficiency in recent years, many of which are very genuine," he said.
