Renault calls the Kadjar and Captur back to NOx-emissions

Since it became known that Volkswagen sjoemelde with the NOx emissions of its diesel engines, is also regularly link with other brands placed. Usually proved to be unfounded posts, but Renault have now final cars back due to high NOx emissions. Big question: is there purposely cheated?

There are going to be for a long time rumors that things would not beat around the emissions of oxides of nitrogen (NOx) of various Renault models. So it was there on 7 January a raid by the French police to the car manufacturer, which, incidentally, is to a considerable extent in the hands of the French government. Later that day, came Renault with a statement that the software of its cars to all rules, and therefore legal.

Nevertheless, it is today known that there are cars back to the dealer for an adjustment. Initially it seemed only to go to the Renault Captur, but after contact with Renault Netherlands shows it in their own country, especially to go to the fresh Renault Kadjar. 173 copies of the Kadjar and 17 Capturs have in our country back to the dealer. It is in all cases to models with the dCi 110 engine, produced in the period from February to september 2015. That the relatively many Renault Kadjar’s going to has to do with the favourable bijtellingstarief that the car is in 2015 still enjoyed. The Captur is much more often by private individuals bought and is also much more common with a gasoline engine sold. There are rumors that also the Espace under the microscope is due to a much to high emissions, but this is by Renault anything yet brought out. The Espace is not available with the dCi 110 engine, the range starts with the slightly more powerful dCi 130, with a capacity of 1.6 – instead of 1.5-liter.

Problems with NOx filter

According to a spokesperson of Renault Netherlands is going to have a problem with the NOx filters of these models. This filter view is in the exhaust system and stores the nitrogen oxides. During the drive, these filters are cleaned, but due to a bug in the software, this would not be often enough to happen, so the filters can get, and so are not functioning well anymore.

According to Renault the Netherlands would be calibration of the software of the car should be sufficient, but Autonews Europe also speaks about the replacement of the old filters. If this is the case, then the whole process by car just a half a day to complete can take.

Big question is if Renault the software deliberately set so that it filters less frequent cleaning than is actually required. According to ANE, the vehicle is the filter to activate at ambient temperatures between 17 and 35 degrees -European uistoottesten be carried out at ambient temperatures between 20 and 30 degrees celcius-while in Europe, of course, settled much colder it is. It does not activate the filters would, in theory, fuel consumption can reduce and/or the performance of the car improve. The undersigned has the suspicion that the raid Renault on January 7, focused on the search of evidence of willful tampering.

Statement from Renault

Later today comes Renault with an official statement about the recall. Perhaps we will have more information about the voluntary software update that Renault, according to some rumors want to offer to the emissions. In the case of these cars there would be no question of a standard, cross-jurisdictional emissions, but can the car be cleaner. Sounds very vague, so let’s hope that Renault later today clarity can create.
