Nissan has been found guilty of using a “trick” device ” in the Renault source 1.6-litre diesel engine in the British-built Qashqai SUV sold in South Korea, the government of the country has been pronounced.
The Japanese manufacturer insists that it has complied with the regulations.
“We’re disappointed with the decision of the court,” a statement from Nissan said.
“Nissan Korea argues that it has complied with all existing regulations and does not use an “unjustified, arbitrary setup’ or illegal defeat device in the Euro 6 Qashqai.”
The South Korean government, however, ruled that the so-called device to lower nitrogen oxide emissions under test, leading to excess emissions of nitrogen oxide when the system is deactivated under normal driving conditions.
The Qashqai models which have been affected were built in the uk and usa 1.6-litre diesel engines from sister brand Renault. Qashqai sales in South Korea have been arrested and 814 models have been withdrawn from the market.
Nissan received a fine of around £300,000 last year after being accused of cheating on their emissions testing, but rejected the claims and sued the government of the ministry of environment.
When it was originally accused the manufacturer strongly denied the allegations by the South Korean government that it had used an emissions defeat device.
The government of South korea independently tested real-world emissions of 20 diesel cars in the wake of the VW scandal, and it was believed that the cheat device discovered that it was linked to Nissan’s emissions reduction Exhaust Gas Recirculation (EGR), that stopped working when the engine temperature reaches 35 degrees Centigrade.
“Generally, some cars turn off the emission reduction device when the temperature reaches 50 degrees Celsius, to avoid overheating of the engine,” a spokesman of the government said at the time. “The Qashqai was the only vehicle that shuts down to 35 degrees.”
