Germany's Federal Motor Transport Authority (KBA) is considering recalling more Volkswagen cars due to its emissions scandal, the Bild am Sonntag newspaper reported on Sunday.
The KBA has opened an investigation into whether a software update for 1.2-litre engine cars, including the popular Polo, enabled them to cheat emissions tests, the newspaper said, without naming its sources.
The Bild am Sonntag said prosecutors were preparing charges against unnamed Volkswagen managers for suspected fraud, noting that the company had given assurances in 2016 that the 1.2 litre engines did not use illegal emissions cheating defeat devices.
