Volkswagen AG’s diesel-emissions scandal just got bigger.

The U.S. Environmental Protection Agency and the California Air Resources Board said Friday that the investigation has been expanded to include every Volkswagen and Audi model with a 3.0-liter diesel engine from model years 2009 through 2016 -- a total of roughly 85,000 vehicles.
