Fench carmaker Groupe Renault has announced that it plans to recall 15,800 vehicles due to a pollution filter that isn't working correctly, Bloomberg reports. The vehicle affected by the recall is the Captur SUV. Production for these cars began in July, the filter problem being found in September, and it was addressed and fixed.

The recall for these cars began in December. Earlier this week, French investigators went into Renault's headquarters outside of Paris on suspicion of fraud, according to the Verge.

Many carmakers have recently been installing software that allows them to effectively cheat on their emissions tests, and authorities believed Renault to be doing the same. The French carmaker later released a press release stating that officials couldn't find any evidence of a device, but that they still had to fix their systems as they weren't adhering to emissions standards.

"Renault has committed to recalling a certain number of vehicles, more than 15,000 vehicles, to check them and adjust them correctly so the filtration system works even when it is very hot or when it is below 17 degrees, because that's when the filtration system no longer worked," said French Energy Minister Segolene Royal after the raid by French authorities, Reuters reports.
