The immediate aftermath of the revelations saw Volkswagen's share price tumble, and the German auto giant and several other major auto companies have since sought to increase their focus on developing lower emission cars and electric vehicles.
The alleged investigations into Germany's premium auto makers, and its suggested link to emissions-limiting technology comes at a tough time for their diesel product lines, Mercedes-Benz's decision to complete upgrades to hundreds of thousands of UK-owned diesel vehicles having prompted a push to prevent the "death of diesel". BMW stated, "As a matter of principle: BMW Group vehicles are not manipulated and comply with respective legal requirements".
It said Volkswagen admitted to possible anti-competitive behavior in a letter to cartel authorities on July 4.
It was referring to reports over the weekend that European antitrust authorities were looking into allegations that Volkswagen, Daimler and BMW colluded illegally to hold down the prices of crucial technology, including emissions equipment.
The diesel-car industry just can't catch a break.
The company said it combined AdBlue fluid to neutralise pollutants as also a system that stored nitrogen-oxide emissions.
The report was published on the same day that the Volkswagen Group said it was voluntarily recalling 850,000 cars from the Audi, Porsche and Volkswagen brands fitted with V-6 and V-8 diesel engines in all major markets except the USA and Canada. The result, as we now know in Volkswagen's case, was the installation of emissions-cheating software, which was uncovered by American regulators in 2015 and has cost the automaker dearly since.
The costs of the rescue plan amount to under 2 billion ($2.33 billion) euros for cars in Germany, with the auto industry agreeing to shoulder the expense of about 100 euros per vehicle, the sources said.
Daimler tried to get ahead of things this week by recalling 3 million diesel vehicles in Europe for a free emissions-system adjustment. This means there is no need to recall or upgrade the software of BMW Group Euro 6 diesel passenger cars. It agreed to pay more than $20 billion in civil and criminal settlements and penalties in the USA and eight executives have been charged there.
Another automaker, Daimler-Benz, also announced a voluntary recall of 3 million Mercedes-Benz diesel vehicles in Europe to update the NOx software.
