Volkswagen said it would recall around 8.5 million diesel-engine cars in the European Union (EU) after Germany requested servicing of the vehicles following a scandal over rigged emissions tests.
VW said on Thursday that it would need to be determined outside the 28-nation EU which classes of engine EA 189 were affected. The latest engine generation EA 288 is not affected, it said.
This came after Germany's automotive watchdog, the Federal Motor Transport Authority, ordered Volkswagen to recall 2.4 million vehicles, according to Reuters news agency on Thursday morning.
The watchdog rejected the voluntary recall of vehicles put forward by Volkswagen in a plan submitted this month, according to German newspaper Bild which first reported the news.
Billions of euros have been wiped off Volkswagen's value following the revelation that the company had used software to change its diesel engines' performance under U.S. test conditions.
