Opel (2009-2019): Aglia, Antara, Astra, Cascade, Combo, Combo C, Corsa, Crossland X, Grandland X, Insignia, Meriva, Mokka, Movano, Signum, Vectra, Vivaro, Zafira

This list may be updated as the investigations by the Foundation are still ongoing.


The Foundation is of the opinion that all diesel vehicles, which were brought on the market in the period 2009-2019 under the Euro 5 or Euro 6 emission standard, are equipped with an illegal defeat device. More specifically, preliminary investigations by the Foundation, indicate that the engines in question may be those listed below.

  • Engine capacity (in cubic centimetres and/or litres):
    • 1248 (1,3 L)
    • 1598 (1,6 L)
    • 1598 (2,0 L)
    • 1686 (1,7 L)
    • 1995 (2,0 L)
    • 2299 (2,3 L)
    • 2464 (2,5 L)
  • Another indication of the presence of an illegal defeat device is the type of motors listed below. Type of motor:
    • G9U (Renault)
    • M9R (Renault)
    • M9T (Renault)
    • R9M (Renault)

Additional car models, or engine types, may be added to this list as the investigations by the Foundation are still ongoing.

The Procedure Against OPEL

Opel used to be the Netherlands’ best-selling car brand. Since 2017 Opel has been part of the former PSA Group, which became merged into Stellantis in 2021. Between 2009 and 2019 Opel sold approximately 110,000 diesel vehicles in the Netherlands alone. The number of vehicles sold on the European market is in the millions.

According to information from the Foundation, all these Opel diesel cars vehicles were provided with illegal defeat devices. These illegal defeat devices ensure that the vehicles concerned `comply` with the EU type-approval emission standards while being tested. The Euro 5 vehicles (that were sold from 2009 to 2014) contained, inter alia, a thermal window that ensures that the emission control systems shut down between temperatures of 20 to 30 degrees Celsius. In addition, the Euro 6 vehicles (2015 to 2019) also included additional illegal defeat devices that ensure that the LNT or SCR catalysts only work properly during testing. When used on the road, the operation of the emission control system is drastically reduced. As a result, Opel’s Euro 6 vehicles do not even meet the Euro 3 standard in normal use. Consequently, Opel is one of the worst polluters in the car manufacturing industry, with emissions that can reach as much as 16 times the applicable emission norm. This diesel fraud has not come to an end yet. Even in January 2022, the German type approval authority, the KBA, has found illegal defeat devices in a large amount of Opel vehicles.

Opel’s Reaction

With its actions Opel has caused extensive damage. The market for diesel cars has plummeted and the value of diesel cars has been reduced considerably. Moreover, the environment and public health have suffered as a consequence of Opel’s behaviour.
The German authorities did initiate criminal proceedings against Opel, but this matter was settled quickly by Opel. In addition, a criminal investigation into the role of various Opel employees is still ongoing in Germany. However, Opel continues to present itself as a “green” company and acts like its unaware of any wrongdoing.

Our goals

Individual car owners don’t have the means to hold large international companies like Stellantis accountable. As a result, large companies tend to go free and leave its customers empty handed. The consequences are amongst others, a lower sales value of the diesel cars on the second-hand market and higher maintenance costs. However, relatively new legislation in the Netherlands, called the WAMCA, makes it possible for representatives like the Foundation to file a collective claim of behalf of all injured parties. In this way, the Foundation can recover compensation to which you may be entitled  on your behalf, without any risk to you. The Foundation has already initiated class actions against five large automotive concerns (of which two are against Stellantis). With this, the Foundation has acquired substantial experience with tracking down illegal defeat devices and identifying affected vehicles. The Foundation has close relations with a leading IT-expert that previously exposed the functioning of defeat devices in cars of different brands, namely Volkswagen, Fiat and Mercedes-Benz. The
Foundation is currently the only Dutch representative that has this type of (technical) expertise. This expertise can and will ensure that the Foundation can make the difference. This expertise is what makes the Foundation the most suitable party to pursue your interests.


In July 2021, another foundation, Stichting Emission Claim, has started a class against, inter alia, Opel. This writ of summons also includes cars of the following brands: Peugeot, Citroen and DS. 

Pursuant to the WAMCA legislation, other claim vehicles that want to initiate a class action based on the same course of events, have to do so within three months after the registration of the first writ. The court may, on request, extend this term. Upon our, and also Foundation Car Claim’s, requests the court has extended this term with another three months.

On 18 and 19 January 2022, the Foundation has issued its writ of summons against the defendants; these include Stellantis as the parent company, Opel and its various related entities (in the US and Germany), the importer and also the Dutch car dealers. The writ of summons has been registered at the Central Register for Class Actions and is accessible through the following link:
