Berlin - Volkswagen says it will take less than an hour to bring 1.6 and 2-liter turbodiesel engines in Europe into line with emissions rules.
The carmaker has pledged to fix 11 million vehicles worldwide that were discovered to contain software that enables them to cheat on emissions tests for nitrogen oxide.
Volkswagen said in a statement on Wednesday that in Europe the 2-liter EA 189 engine will require only a software update taking half an hour to install.
It says the 1.6-liter engine will be fitted with a grid to improve the motor's efficiency, taking less than an hour.
Volkswagen says the measures only cover Volkswagen-branded models in Europe and should be completed by the end of next year. A proposal for the 1.2 liter models will follow.
TROUBLE IN SOUTH KOREA
Meanwhile South Korea has fined Volkswagen $12.3 million (R174m) and ordered recalls of 125 522 diesel vehicles after the government found their emissions tests were rigged.
Hong Dong Gon, a director at the Ministry of Environment, said in a live television broadcast that the ministry will continue investigating 30 000 other Volkswagen diesel cars for which it did not find evidence of emissions cheating.
South Korea's government launched investigations last month after the German automaker admitted that it rigged US tests.
The South Korean ministry found that emissions from the Tiguan diesel using EA189 engines breached standards when the car was not under the usual test conditions, such as when the air conditioner was on or when the car accelerated.
Volkswagen was ordered to recall 125 522 diesel vehicles equipped with the same EA189 engines sold in South Korea between 2008 and 2015.
The ministry will continue investigating Golf, Beetle, Jetta and Audi A3 diesel cars using more recent EA288 engines.
The ministry will also expand the investigation into other auto brands. It said it will announce the result in April after probing emissions levels in diesel cars sold by five local car companies and 11 imported brands.
