From a long time ago we were warning of this. The fact that Volkswagen had admitted the existence of a software that’s designed to manipulate the outcome of the approvals emissions NOx would affect all of the automotive industry. And that is what seems to be happening judging by the news which arrived from Germany, who speak of a call to review which initially could affect 630,000 vehicles, not only Audi, Porsche and Volkswagen, but also of Opel and Mercedes-Benz. How and why is this new news? Have you incurred other manufacturers in the trick of the Volkswagen Group?
Audi, Volkswagen and Porsche, the spotlight is now moved also to Opel and Mercedes-Benz.
as they are publishing the German media, and we read already in Automotive News, the German authority for transportation, the Kraftfahrt-Bundesamt (KBA for short), has requested the review than 630,000 vehicles belonging to the brands already mentioned. A decision that comes after knowing the results of the emissions testing that have been taking place in recent months in the wake of the scandal of Volkswagen.
In any case, since Germany already points in a direction very concrete. it does Not appear that other manufacturers have souped-up software engine for cheat the approval process, but that would be doing a use a both ity of the technology used in the systems anti-pollution to come out ahead in these tests. And not only that, be alert that this practice would be widespread.
The logic of operation of the systems, anti-pollution and gas treatment would be taking advantage of to get benefited in approval, with procedures that are not always justified by the need to protect the engine.
If in the case of Volkswagen, it used a particular software that was able to cause the engine to behave in a specific way during the approval testing in bank roll, the hole that would have detected the German authorities aims at a technique much more subtle, a trick that a priori would be within the scope of legal, both in Europe and in the united States.
The gas treatment systems of the modern diesel working under a logic of operation is very specific, that depends on driving conditions, or even the engine temperature and the saturation of the filters, so that the work of the systems anti-pollution adapts to these circumstances in order to avoid damage. That way, in certain circumstances the systems work at full capacity to reduce emissions, but that is not always the case.
The KBA would have discovered that, with the excuse of protecting the engine and the systems anti-pollution, the logic of operation of these gas treatment systems are benefiting the manufacturers in the approval processes, in circumstances that don’t always explain that it is necessary for the system to work that way to protect themselves. That is the reason, which would explain the large deviation between the figures obtained by many diesel passenger cars in the approval testing at bank of rollers, and in actual conditions of circulation (Handelsblatt).
List of affected models
* Audi Q5 (22.000 vehicles), Audi A6 (to 29,000 vehicles), Audi A8 (15,000 vehicles)
* Mercedes A Class and Mercedes B Class (211.000 vehicles), Mercedes V-Class (36,000 vehicles)
* Opel Zafira (58.000 vehicles), Opel Cabrio (1,000 vehicles), Opel Insignia (31.000 cars)
* Porsche Macan (32,000 vehicles)
* Volkswagen Amarok (70.000 vehicles), Volkswagen Crafter (124.000 vehicles)
In the next few days we should know more details on this news, as well as the reaction of those involved. What seems to be clear is the fact that the scandal of Volkswagen is serving, as a minimum, to put more attention (albeit at a much slower pace than we would like) in the tricks that are legal that are used probably by all or almost all of the manufacturers, to get benefits in the approval testing.
And as a final reflection we drop a question: what is the problem, that the manufacturer take advantage of a loophole within the rules set out in the approval, or that that methodology approval be given to the existence of loopholes that can be exploited?
