Volkswagen chief Matthias Mueller is expected to present a technical solution for diesel engines fitted with data-manipulating software in an attempt to appease US environmental authorities, a German newspaper reported on Sunday.
Germany's embattled automaker has developed a new catalytic converter, which could reduce emissions accordingly with regulations, the Bild am Sonntag said.
Mueller is to present the technology to Gina McCarthy, head of the US Environmental Protection Agency (EPA), at a meeting in Washington on Wednesday, according to the report.
A civil complaint was filed in federal court in Detroit last week on behalf of EPA, alleging that VW's so-called defeat devices masked the cars' actual emissions, resulting in harmful air pollution
There are an estimated 600,000 rigged VW cars on US roads. According to the report, the company intends to retrofit 430,000 of them with the catalytic converter, provided the device is approved by EPA.
A spokesperson from VW was not available on Sunday to comment on the report.
