Belgian journalists: Opel secretly tampered with software
Opel secretly gives the Zafira Tourer 2014 a software update in order to achieve lower emissions of harmful gases. That update is performed when the cars go to the garage for anything else. The owners get to hear nothing of that update, while the cars lose power, the Belgian broadcaster VRT reports based on its own research ….
Then the cars were taken to the garage of an Opel dealer with an excuse. After the cars had returned from the garage, the same car emissions tests were performed again. It showed that the harmful emissions of the cars had fallen by tens of percents. Also, the power of the cars had diminished, the VRT reported.
A secret camera recorded that garage employees confirmed that they do an update. In their own words they had started that after the scandal of Volkswagen’s fraudulent software came out.
No, this pollution fraud may be good for the profits of General Motors fat cats. But the pollution makes many people and animals sick and kills quite some of them. In the USA, in Germany, in Belgium, anywhere.
