Volkswagen BluemotionSwiss authorities have halted the sale of Volkswagen Group cars fitted with diesel engines believed to contain emissions test manipulation software.

The move by the Swiss Federal Roads office relates to 180,000 Euro 5 cars yet to be sold or registered; 1.2-litre TDI, 1.6-litre TDI and 2.0-litre TDI engines are all affected.

The sales ban is not restricted to Volkswagen vehicles either: Audi, SEAT and Skoda cars are also hit by the official sales halt.

Euro 6 emissions-compliant cars are unaffected and can continue to be sold; the Euro 6 standard was made mandatory for all cars sold in the European Union.

Although Switzerland is not an EU member, the switch to Euro 6 still applies there.

The Swiss Federal Roads office also added that Volkswagen Group cars already on the road can continue to be driven as normal.
