Models Volkswagen , Audi and Porsche with the 3.0 V6 TDI sold in Europe use the same software than for America. This was reported by the British edition of the Reuters , citing the same manufacturer of Wolfsburg. Who in recent days has taken the field to defend the six-cylinder from accusations EPA: according to the American agency for environmental protection, the three-liter would assemble a “defeat devices” similar to the one that helped the four-cylinder 189 EA to mask the emissions of NOx in the approval.
“AECD”, not “defeat devices”. The Volkswagen, confirming the presence of the vehicles sold in Europe, denied again the irregularity of the “AECD” (auxilary emission control device), but gave no precise data on how many cars are equipped with this software were sold in Europe.
An estimate of the volumes at stake in Europe. The Manufacturer has merely confirmed what was already anticipated by the EPA, and that is that the total number of individuals in the US is more than ten thousand. However, according to the estimate of a Barclays analyst quoted by Reuters, the volumes in the old continent could be “up to twenty times.”
What is (and what it does) the AECD according to VW. Wolfsburg, according to the latest developments, seems to want to insist on the substantial difference between the “defeat devices” of the four-cylinder – device designed to circumvent the controls – and the ” auxiliary emission control device “of the V6 , it was meant completely different purpose: “The software AECD does not alter the levels of emissions, but makes after a cold start, the catalyst reaches operating temperature as soon as possible, reducing the levels of pollutants.” The House also added that this second “device” would be present not only on the “three thousand”, but also on two liters of some model year 2016.
In the next hours the meeting with ‘ epa. According to two sources within VW cited by Reuters, in the next few hours there will be a meeting between representatives of the House and the EPA: Audi, according to the reconstruction, will have a separate meeting with the agency, scheduled for the next week. The goal, according to the insider, is to tear in Washington for permission to continue using the AECD.
The skepticism of Carb outcome. will be tough, according to Mary Nichols, head of the California Air Resources Board, convince “watchdogs” federal: the EPA has repeatedly observed emission levels rise an instant after the end of the test. “Can not explain such behavior, if not with the presence of software that regulates the emission controls,” he said Nichols.
