Controversial software for the determination of exhaust gas values in clearance tests was declared illegal. The ruling could significantly strengthen the rights of owners of older diesel cars.
Five years after the start of the VW diesel scandal, the European Court of Justice has outlawed the controversial software to fine exhaust gas values in approval tests. The verdict came in Luxembourg on Thursday. It could significantly strengthen the rights of owners of older diesel cars. (Case C-693/18)
With the ruling, the judges significantly restrict the authorization for deactivation devices in diesel cars. The judges decided that the blanket ban on deactivation devices would be undermined if the engine could be protected from dirt and wear. The ruling published Thursday shows that such techniques should only be used to guard against sudden engine damage that poses a specific hazard while driving.
Therefore, the ECJ supported the opinion of the Advocate General, who had declared such exhaust gas cleaning techniques inadmissible in her final argument at the end of April. Exceptionally, these could only be approved if the device was necessary to protect the engine from damage or accidents.
