ZURICH -- Swiss authorities have halted registrations of some new Mercedes-Benz Vito vans and Porsche Macan and Cayenne SUVs that had diesel engines that disguised emissions levels, the Astra roads agency said on Wednesday.
The move will affect vehicles imported from Aug. 17.
Vehicles already registered in Switzerland may continue to operate, but must be retrofitted, Astra said in a statement.
Mercedes Vitos with 1.6-liter diesel engines, Porsche Macans with 3.0-liter diesel engines and Cayennes with 4.2-liter diesel engines are affected by the action.
Daimler said it had stopped exporting the Vito after German authorities in May ordered a recall and halt to new registrations for the vehicle. This affected 24 Vito vehicles destined for Switzerland, a spokesman for the German manufacturer said in an emailed statement.
