Mercedes-Benz plans to appeal after a German court ruled against it in a class action case over alleged use of diesel emissions defeat devices in its cars.

In the latest episode of ongoing ‘dieselgate’ claims against certain vehicle manufacturers, the Stuttgart court found that some of Mercedes’ Euro 6 diesel models built between 2012 and 2016 were equipped with emissions cheat devices.

Mercedes’ Euro 5 level diesels were found to not be affected.

The court said owners of affected Euro 6 cars may be eligible for a refund, minus wear and tear, if the violation is confirmed, reports Reuters.

The Federal Association of Consumer Organisations (VZBV), which brought the case on behalf of around 2,800 consumers, sees this ruling as a significant step for damages claims.
