During a routine test, story the European Commission’s experts uncovered in 2010 that a certain vehicle was fitted with some sort of emissions cheating device, report says.
Documents obtain by The Guardian reveal that the European Commission was informed as far back as 2010 by its own researchers that a carmaker is suspected of using an emissions bypass device, five years before Volkswagen was caught manipulating the tests of around 11 million diesels. “One vehicle tested showed extremely high NOx emissions during the low temperature type 6 test,” the report said. “Since NOx emissions at low temperature are currently not regulated, this observation hints towards a very peculiar combustion strategy (defeat strategy?) the manufacturer applies at low temperature.” It is unknown what particular vehicle was targeted by the report, but the description of expert’s findings is similar to the “thermal window” software that has been lately uncovered as having being used by many automakers.
The green group Transport & Environment recently said it identified around 30 highest polluting new Euro 6 diesel cars from 21 carmakers on European roads. The group claimed that almost all the blamed models – 29 – indicated the presence of a “thermal window” defeat device, which switches off or lowers the effectiveness of the exhaust treatment systems at temperatures below those typically used during laboratory tests.
The scientists who warned about the emissions scheme in 2010 told the European Parliament’s ‘dieselgate’ inquiry team that they were never given a mandate to investigate the defeat devices further issued. Furthermore, they once again raised red flags in 2013 around “increasing evidence of illegal practices by car manufacturers that defeat the anti-pollution systems to improve driving performance or save on the replacement of costly components.”
