After Volkswagen’s deception emerged, South Korean officials started investigating the emissions systems of 20 diesel models in the country. As part of that effort, the Environment Ministry of South Korea said on Monday that it had discovered that Nissan had manipulated the emissions of its Qashqai diesel-power sport utility vehicle. The authorities said it had found problems with emissions levels in some other cars, but no cheating mechanisms like the one the Environment Ministry said it found in the Nissan model.

Nissan disputed the accusations, adding that the model in question had passed European pollution tests. The cars are made in Britain. “Nissan has not and does not employ illegal defeat or cheat devices in any of the cars that we make,” the automaker said in an email statement.

The potential hit to Nissan is more reputational than financial.

Officials ordered Nissan to recall 814 cars, the total sold in South Korea. The company was also ordered to pay a fine of 330 million won, or about $280,000, and to suspend sales of the Qashqai. The Environment Ministry also said it would ask prosecutors to indict the head of Nissan’s South Korean operations, Takehiko Kikuchi, on criminal charges of violating the country’s emissions law.

Carmakers have been under increasing scrutiny since Volkswagen’s deception emerged.

The United States Justice Department is investigating Daimler, the maker of Mercedes vehicles, over emissions testing. As part of an inquiry into potential emission anomalies, French authorities collected documents from the PSA Group, the parent of Peugeot and Citroën.

German regulators last month recalled 630,000 cars over emissions issues, a group that includes vehicles by General Motors’ Opel unit, Mercedes-Benz and Volkswagen. The country’s officials are also looking into whether Opel and Fiat used manipulated software similar to the device found in Volkswagen vehicles. Opel officials are set to testify before an investigatory committee in Germany this week.
