But Der Spiegel said that the KBA vehicle licensing authority is now set to recall some Mercedes-Benz Vito vans produced by Daimler, as well.
The suspicions this time concern a software device that regulates the amount of a special fluid known as AdBlue used in the engines to neutralise harmful nitrogen oxides (NOx).
Nitrogen oxides are poisonous, can contribute to acid rain and suffocating smog and can cause breathing problems and headaches in humans.
