While the report concluded that some Renault models emitted many times more nitrogen oxides (NOx) on the road than during the official emissions test, it did not mention that a Renault Captur SUV was observed to perform a cleaning procedure on its lean NOx trap (LNT) five times in a row when the prescribed preparations for emissions testing where made, rendering it much more effective in the test than under normal conditions.
Three members of the enquiry commission told the Financial Times that the French state, which owns a 20% interest in Renault, decided that these findings should remain confidential. A spokesperson of the French environment ministry denies that facts where hidden on purpose. Meanwhile, the anti-fraud agency in France continues its investigations into Renault's emissions practices.
Renault has repeatedly denied any wrongdoing, but it has agreed to voluntarily recall 15,000 cars to perform a software update that should reduce NOx emissions.
