German authorities question Opel over diesel vehicles
Asked the company to answer questions about emissions
16 July, 11:44Germany's transport ministry confirmed a report by weekly Bild am Sonntag late Friday that authorities have asked the company to answer questions about the way the emissions cleaning system in three of its models works.
Opel's rival Volkswagen was found three years ago to have used a so-called defeat device to ensure its diesel cars reduce emissions in official tests, but not during regular driving.
