In May Germany’s Federal Motor Transport Authority accused FCA of using a special software that would switch of the exhaust treatment system on the 500X 22 minutes after the engine began operation. This would allow it to easily pass German emissions standards, as the test typically lasts 20 minutes.
At a recent European Parliament inquiry committee meeting, FCA chief technical officer denied the findings and said the 500X meets Euro 6 standards without having to resort to a cheat device.
“The 500X meets the relevant Euro 6 limit in the regulatory NEDC test and does not detect that it is being tested,” Wester said.
“Contrary to allegations, 500X does not deactivate its emission control system but uses control strategies which modulate the emissions control system solely to protect the integrity of the engine and the safety of the vehicle occupants in accordance with applicable regulations.”
Committee members reportedly asked Wester to elaborate on the 500X’s diesel emissions cheat system. Wester was also questioned about French emissions test that showed emissions levels on the 500X that were 15 times greater than FCA claims, but he said he would need to see more data on those tests in order to elaborate.
