Antuan Goodwin, CNet.com; Volkswagen apologizes, stops diesel sales in wake of US emissions scandal:

"Volkswagen Group is apologizing after the US Environmental Protection Agency accused the automaker of using illegal software in its TDI diesel cars to skirt US emissions standards.

In a statement over the weekend, Volkswagen Group CEO Dr. Martin Winterkorn said he's "deeply sorry that we have broken the trust of our customers and the public." The German automaker ordered its US Volkswagen and Audi dealerships to halt sales of affected vehicles until a fix can be issued. In a further statement, issued Tuesday morning, VW indicates that 11 million Volkswagen Group autos (which includes Audi, Porsche and other brands) contain the software, and that the company has set aside EUR 6.5b to address costs.

The EPA claims certain VW and Audi vehicles use software that meets clean diesel emissions standards when hooked up to testing equipment but then switches to a dirtier mode when disconnected."
