Around 3.6 million Volkswagen 1.6-liter TDI cars sold in Europe will require hardware changes as well, according to a spokesman for the German transport ministry.

As previously reported, the Environmental Protection Agency (EPA) has issued Volkswagen and Audi a stop-sale order for 2015 and 2016 2.0 TDI models until the German car maker fixes the cars.

Volkswagen sold a total of 8 million diesel cars in Europe that are equipped with an illegal software called “defeat device.” The said illegal software is fitted onto the EA189 1.2 TDI, 1.6 TDI and 2.0 TDI engines.

Based on reports, the 2.0 TDI will only need a software revision while the 1.6 TDI require hardware modifications. This affects 3.6 million 1.6 TDI Volkswagens sold in Europe, which includes vehicles from Volkswagen Group brands such as Audi, Skoda and SEAT.
