Volkswagen is reportedly in the testing stage for the repair to its emissions-cheating 3.0-liter TDI V6 in the United States. However, a lawyer for the U.S. Justice Department said the process could still take months, Automotive News reported. In a further sign of a potentially long wait before a recall, District Judge Charles Breyer scheduled an August 25 hearing to get an update on the situation, but he didn’t set a hard deadline for the automaker to have the fix ready.

"The company believes that we can fix the 3.0-liter to the standards to which those cars were originally certified," VW lawyer Robert Giuffra told Reuters, Automotive News reported. There would also be no affect to the models’ performance, the attorney believes.

In November 2015, the U.S Environmental Protection Agency found that VW had emissions control devices on the 3.0 TDI in 85,000 vehicles in the country, but the automaker hadn’t told the government agency the equipment was there. The problem affects certain 2009-2016 examples of the VW Touareg, Porsche Cayenne, the Audi A6, A7, A8, and Q5.

Audi took the lead on creating a fix and has been working on the problem since at least early December. At the time, company chairman Rupert Stadler promised "swift, straightforward and customer-friendly solutions are in discussion." A report in May suggested the repair could involve installing a new catalytic converter on the vehicles.

While installing new parts could be expensive and time-consuming, it would potentially avoid another vehicle buyback. VW agreed with American government representatives to spend over $15 billion to purchase the cheating 2.0-liter diesel vehicles from owners and to invest in environmental cleanup.
