Daimler is being forced to recall hundreds of thousands of diesel-powered models due to emissions issues, including a total of 260,000 Sprinter vans.

The recalls were spurred on by Germany’s road traffic regulator, KBA, who concluded that certain Mercedes-Benz vehicles equipped with OM651 Euro 5 diesel engines needed to be serviced, as reported by Autonews Europe.

Meanwhile, according to German outlet Bild am Sonntag, a recall of Mercedes Sprinter models was also imminent after the KBA warned Daimler that the vans might have illegal engine management software.

“Mercedes-Benz customers will be notified in writing over further actions if their vehicle is subjected to the recall and a software update can be installed,” stated the automaker. Out of a total of hundreds of thousands of cars, 260,000 units are Sprinter vans belonging to a previous generation – the one that went out of production in 2016.

It’s also been reported that KBA proceedings with regard to engine control functionality have yet to be concluded, which means the regulator might send Daimler further notices if needed.

Back in September, Daimler received an 870 million euro ($960 million) fine for not respecting diesel emission rules, a fine that the automaker did not appeal. German prosecutors had found that Mercedes-Benz had sold roughly 648,000 vehicles that didn’t comply with emission standards.

“It is in the company’s best interest to end the administrative offense proceeding in a timely and comprehensive manner and thereby conclude this matter,” said the carmaker at the time.

Like with that fine, this recall will also not significantly affect earnings, according to the German brand.
