The company has upcoming meetings with regulators and the court, which could bring a resolution to the issue.

Volkswagen Group’s 3.0-liter TDI V6 engines allegedly contain three new software defeat devices, according to Automotive News citing a report by Bild am Sonntag. The German publication doesn’t reference a source for these claims, though. More info could come to light when Audi executives meet with American regulators on August 10.

According to this new report, the defeat devices allegedly turn off the emissions systems after 22 minutes, which means the tech is active just long enough for regulators’ 20-minute test.  The Environmental Protection Agency discovered the cheating last year shortly after finding something similar in the code for VW’s 2.0-liter diesel four-cylinder engine. In November 2015, VW Group admitted the software was in about 85,000 vehicles with the 3.0-liter TDI, including models from Audi, Porsche, and Volkswagen.

Volkswagen Group attempted to mend the problem with an undisclosed repair, but the California Air Resources Board rejected the fix. The agency called it “incomplete and deficient in a number of areas” without going into much detail. The regulator also claimed that VW didn’t provide enough data proving this solution worked. Before CARB’s ruling, Audi seemed confident its proposed repair solved the issue.

VW has a court hearing on August 25 where it intends to submit an updated repair proposal. If the automaker can’t create a satisfactory fix, CARB could demand the company buy back the polluting vehicles. Since they include luxury models like the Porsche Cayenne, Audi A6, A7, A8, Q5, and VW Touareg, the total cost could be huge, if that happens. The business already agreed to pay around $15 billion for buybacks and environmental damage from the 2.0-liter TDI.
