The Irish Government is likely to begin an investigation into whether the scandal over Volkswagen emissions has affected Irish customers.
The motoring giant has confirmed the software at the centre of the scandal in the US was built into its cars in Europe too. It is not yet clear whether it helped cheat tests as it did in the US, Germany said.
The US Environmental Protection Agency (EPA) disclosed on Friday that stealth software makes VW’s 2009-2015 model cars powered by 2.0-litre diesel engines run cleaner during emissions tests than in actual driving.
Tánaiste Joan Burton confirmed today that the Department of Transport was likely to investigate the local impact.
Speaking in the Dáil, she said: "I'm sure the Department of Transport and Minister of Transport will be examining this matter.
"There's an amount of conflicting evidence as well as to whether exactly the same mode of testing applies in the European market, as appears to apply in the American market - but it's certainly extremely disturbing."
