Renault, which announced a recall for 15,800 Captur SUVs to fix a faulty emissions filtering system, isn’t the only automaker to be in the spotlight over having models with questionable emissions levels following a French government probe into the matter.
Following Volkswagen’s dieselgate scandal, the French government initiated a probe to verify if vehicles sold in France had equivalent devices installed. An independent technical committee was formed, with emissions testing being carried out by the UTAC (French Homologation Authority). The exercise involved a total of 100 models from various manufacturers, including 25 from Renault.
French newspaper Les Echos reported that Ford Motor and Mercedes-Benz is also under scrutiny after two of the automakers models, the Ford C-Max and Mercedes-Benz S-Class, also displayed emissions exceeding legal levels following tests.
The paper stated that the vehicles underwent three tests – the standard New European Driving Cycle (NEDC) run, to establish whether vehicles meet EU limits, a road test that isn’t currently part of the official EU procedure, as well as a check to see if the vehicle was utilising a defeat device.
The S 350 BlueTEC diesel that evaluated returned inconsistent results, while the C-Max had emissions five times above the allowable limit, the paper stated. It said that UTAC had tested Euro 6 versions of both cars.
Les Echos also reported that in tests, the Volkswagen Tiguan and Audi Q3 models proved the existence of fraudulent software. Meanwhile, the Peugeot 208 and 508, a BMW 3 Series variant as well as an unnamed Toyota model showed no particular problems.
