Washington — US regulators say they expect to receive a proposed fix later in October for some diesel Volkswagens caught-up in the German automaker's emissions-rigging scandal.
Emissions control technology
Environmental Protection Agency spokeswoman Laura Allen said Thursday the proposed software patch would be for 2012 to 2014 Passat TDI models. The sedans have what VW refers to as its Second Generation emissions control technology. About 90 000 of these cars were sold in the United States.
Regulators must approve the proposed fix before it can be distributed to VW dealers and uploaded to customers' cars.
Owners of cars in the Generation 1 and Generation 3 categories are expected to have a longer wait. That includes nearly 400 000 diesel versions of the 2009 to 2015 model year Jettas, Golfs and Beetles, as well as 2015 Passats.
