But about 85,000 drivers who own similarly afflicted diesels with 3.0-liter engines have been stuck without a remedy. They may not be waiting much longer.
Bloomberg reports that Volkswagen will soon propose a fix for vehicles, including those from Audi and Porsche, equipped with 3.0-liter engines that will include new software and a new catalytic converter for the vehicles. Discussions with federal regulators are ongoing, according to the news outlet.
"We are cooperating with the regulatory agencies and working with them on an approved solution," says Audi spokesperson Mark Clothier. "Beyond that, we cannot comment on ongoing investigations."
Regulators have alleged that the company's 3.0-liter engines contain "defeat devices," illegal software that allows a vehicle to detect when it's undergoing an emissions test and turn off pollution control during real-world driving. The defeat device allows these vehicles to increase emissions of nitrogen oxide up to nine times the Environmental Protection Agency's allowable threshold.
Affected 3.0-liter vehicles include the 2014 Volkswagen Toureg, 2015 Porsche Cayenne and the 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5.
Volkswagen is slated to finalize its plans for buying back the afflicted 2.0-liter cars and potentially offer those motorists "substantial compensation" for their troubles by June 21, and it's possible that a formal announcement on the 3.0-liter vehicles would come at the same time.
