With a roughly applied attempt, the german environmental help (DUH) wants to detect the automaker BMW the use of a shutdown in at least one case. The DUH had notified after tests with a 2016 built BMW 320D touring with automatic, the exhaust values suggested that BMW used a so-called shutdown device. Tests in the strain operation had significantly higher exhaust values than in the laboratory. However, this is not enough as proof yet.
BMW has prompted the burrs of the DUH immediately. "There are no activities and technical precautions in the BMW group to influence the prufmodus for the collection of emissions," said the group on monday evening (4. December 2017) on request with. "Limitally applicable that BMW vehicles comply with and are not manipulated each of the leasher law."BMW stressed, the TUV sud had already tested a technically identical model in 2015 while not detecting any procedures. The DUH wants the results on tuesday (5. Introduce december 2017) in berlin. Previously, the ZDF broadcast had wiso as well as the daily newspaper daily mirror (edition of 5. December 2017) reported.
When the DUH is experienced, it was found that exhaust prere relief is switched off above 3500 / min. This increases the nitric oxide values (nox) strongly. Why, BMW did not want to tell. In addition, in a test on the strain, the values in the exact descendant of the NEFZ was just above the permissible limit value. If, according to the DUH, was only minimally faster, the nox values rose sharply.
