NEW YORK (TheStreet) -- Volkswagen (VLKAY)  stock is rising 1.61% to $25.90 in mid-morning trading on Wednesday as the company released early results of its internal investigation, which found irregularities in carbon dioxide emission data.

The German company estimates that about 800,000 vehicles have been emitting more carbon dioxide and consuming more fuel during normal driving conditions than during the certification process.

Volkswagen expects expenses to reach about 2 billion euros and plans to cooperate with regulatory agencies on the matter.

Most of the vehicles affected are diesel-powered engines, but these findings are the first to find irregularities in gasoline engines.

On Monday, the Environmental Protection Agency claimed an additional seven models have defeat devices that allow the vehicles to emit nitrogen oxide at up to nine times the federal standard when the vehicles is not being officially tested.

Volkswagen admitted in September that five models had these devices, but denied the latest allegations.

TheStreet's Jim Cramer, portfolio manager of the Action Alerts PLUS charitable trust portfolio, has this to say about Volkswagen: "They are boosting incentives and selling a lot of cars and they will get through this, but I would not be a bottom fisher of that stock. It is a crown jewel of Germany and it will survive, it just won't thrive."
