Volkswagen has agreed last year to offer to buy back up to 475,000 2.0 liter diesel vehicles that had been sold in the U.S. and now its plan for 84,000 older Volkswagen diesel vehicles has been approved by the U.S. Envirnomantal Protection Agency and California Air Resources Board. Friday’s announcement covers a fix for 84,390 2012-2014 Passat diesel vehicles with automatic transmissions. A fix for vehicles with manual transmissions has not yet been approved. In January, regulators approved a fix for 67,000 2015 model diesels, leaving around 325,000 older vehicles still awaiting approval for a fix. VW spokeswoman Jeannine Ginivan said the automaker is pleased that it has received regulatory approval for the fixes. EPA confirmed its approval in a letter posted on its website on Friday.
