The case exaggerated nitrogen oxide emissions at Renault promised as early as November 2015. At that time indeed, the German association Deutsche Umwelthilfe (DUH) had put forward emissions NOx actual driving conditions in excess of 13 to 25 times those recommended by the standard in the measurement cycle. Not enough to highlight any cheating, but simply ineffective pollution control technology in some cases driving.
A month earlier, the DUH had worn more disturbing accusations about an Opel Zafira Tourer 1.6 CDTI . The association had highlighted NOx emissions above average but above differences depending on the protocol. The specimen tested (with 6000 km on the odometer) had significantly lower emissions when the tester did not cause the front wheels and not four, leaving suspicion of software to detect if the car is test protocol, on a test bed.
The cheating accusations supported by a Belgian journalist
A Belgian journalist from the Flemish VRT television network supports these accusations of other elements. Owner of a Zafira Tourer, he has been summoned to the dealer for a software update. During this operation, the mechanic would have told him that this update called 15-P-044 was designed to make adjustments on a model that exceeded pollution standards. From there to infer that the Zafira Tourer has a software fraud emissions, there is a step that the journalist VRT passes.
According to Opel, the update in question has nothing to do with the levels of polluting emissions. “Opel categorically refutes the allegations made on the air during the VRT television that day newspaper according to which Opel dealers could have changed a Zafira Tourer 1.6 diesel a management software in order to change the emissions. The ‘update operation 15-P-044 to which reference is made is unrelated to the level of emissions engine. Moreover, no further recall campaign was launched in 2015 which was intended to improve emission values. The maintenance 15-P-044 has been reviewed by the KBA agency in charge of approvals in Germany. “
Opel refutes accusations
In the same statement, Opel Belgium argues that brand cars are not equipped with a cheat software: “As we have already communicated several times in recent months, we still confirm a Once the software developed by GM has no function capable of detecting that the vehicle is undergoing a test of exhaust emissions. Moreover, Opel reported in December that he wanted proactively and on its own initiative, take additional measures to meet future emission regulations for both NO x as for CO 2 . From summer 2016, in addition to the official consumption figures and CO 2 , Opel also publish consumption figures calculated according to the new cycle WLTP (Worldwide Harmonized Light Vehicles Test Procedures Procedure global harmonized test for passenger cars and light commercial vehicles).
In addition, diesel engineers have recently launched an initiative to improve the technology SCR (Selective Catalytic Reduction or SCR) applied to diesel engines to further reduce emissions of NO x . This is also a proactive initiative and conducted at the initiative of Opel in preparation for the RDE regulation (Real Driving emissions) that will take effect in 2017. Opel is committed to its customers and wishing maximum clarity and transparency. “
