Volkswagen said two days ago that an issue involving potentially inaccurate reporting of carbon emissions in cars sold in Europe is "largely concluded."

The problem--entirely separate from the ongoing diesel-emissions scandal--involved "irregularities" in carbon dioxide (CO2) emissions levels in roughly 800,000 European-market vehicles, producing fuel-economy figures that were too high.

But after further investigation, VW says only a small number of cars actually require adjustments to their fuel-economy ratings.

It says "slight deviations" were found on just nine model variants, the majority models not sold in North America.

This conclusion was drawn from an internal investigation. Volkswagen says the models will be re-tested by an independent party--supervised by regulators--by Christmas.

The company denies that it intentionally changed fuel-economy figures.

The affected cars are all European-market 2016 models, and encompass both gasoline and diesel powertrains.

They include multiple variants of the Jetta and Passat Variant (wagon), as well as versions of the Passat Alltrack, Golf, Golf Convertible, Scirocco, and Polo.

Volkswagen said that these models represent a production total of 36,000 vehicles annually.

It also claims the actual overstatement of efficiency is small, representing just a "few grams" of CO2 on average.

VW originally estimated that reporting issue could cost it up to $2.2 billion--on top of the $7.3 billion set aside to cover costs related to its earlier admission of installing "defeat device" software in 11 million diesel cars.

But because of the apparent smaller scope of the emissions-reporting issue, Volkswagen now believes the financial impact will be minor.

Dealers will be able to sell the nine affected 2016 models once the adjusted fuel-economy figures are verified and published.

All other models previously implicated can be sold and driven without restriction, the carmaker says.

Meanwhile, Volkswagen continues to work slowly to repair the damage from the diesel-emissions scandal.

In the U.S., a proposed fix for 482,000 cars equipped with 2.0-liter TDI powertrains was recently submitted to regulators, but no details have been made public.

A separate group of 85,000 vehicles equipped with a 3.0-liter V-6 TDI may only require software changes, Audi's CEO said this week. No timeline for the implementation of that fix has been discussed either.
