One part of the layered cake that is Dieselgate might soon be dispensed with, provided the Environmental Protection Agency and the California Air Resources Board deem it so.

Volkswagen has submitted a proposed fix for its 3.0-liter diesel vehicles in the US, which possess undeclared software that modifies emissions output, regulators claim. This issue affected some 80,000 cars spanning the Volkswagen, Porsche and Audi brands.

"We are fully cooperating with the US authorities to make our V6 3.0L [diesel] engine compliant with regulations," said Audi spokesman Mark Clothier. "Now the authorities will review the plan and determine whether it meets their requirements."

The EPA confirmed its receipt to us via email, and CARB confirmed receipt of the plans in a statement posted on its website. After a "thorough and complete review," the EPA and CARB will say whether the fix is good to go, the CARB statement said. Autoblog reports that CARB has 20 business days to figure that out.

This may put the 3.0-liter diesel woes in the rearview mirror, but Volkswagen is still trying to get a fix lined up for the 480,000 or so 2.0-liter diesels still emitting more than is legally permissible. CARB denied a previous submission because it was considered lacking.
