Volkswagen boss vows to be 'part of solution' on diesel

FRANKFURT: Volkswagen CEO Matthias Mueller said the automaker had "an excellent year" in 2017 and is committed to addressing concerns about diesel pollution. Mueller cited the company's efforts to reduce diesel emissions and recover from its 2015 diesel emissions scandal. He said 160,000 older diesels had been taken off the road through trade-in incentives, and decided to update software on cars.
