Volkswagen is close to resolving part of its emissions-cheating scandal in the US, which would inadvertently reduce the costs of running a buyback program.

Autonews reported that talks are ongoing and that sources asked not to be identified, but it seems that a potential upgrade for 3.0-liter V6 diesel-powered models may include a new catalytic converter.

Even though a plan to recall V6 TDI models was proposed back in February, talks have since been delayed as US regulators and VW focused their efforts on issues that plagued the 482,000 vehicles with smaller diesel engines.

While VW is racing to meet their June 21 deadline concerning 2.0-liter TDI four-cylinder models, issues affecting larger-engine VW, Audi and Porsche models could be addressed during a new status briefing said to take place on May 19th.

In the US, the V6 TDI power unit is being used in multiple Audi models, such as the A6, A7, A8, Q5 and Q7, as well as the Porsche Cayenne and Volkswagen Touareg SUV.

The German company has set aside 228 million euros for costs originating from the emissions crisis.
