Volkswagen AG is expected next week to provide U.S. and California regulators with a preliminary attempt at a software fix for the defeat devices it installed in 2012-2014 Passats, the U.S. Environmental Protection Agency said on Thursday.In an email response to a Reuters query, EPA said Volkswagen told regulators it would deliver the software to the agency and the California Air Resources Board in an attempt to “address and correct” the illegal software algorithm that the carmarker admits to have used in its diesel vehicles to evade U.S. emission standards. “EPA and CARB will immediately begin evaluating the proposed software,” the EPA said.
