Renault recalls more than 15,000 diesel cars after emissions tests

French carmaker acts after admission that emissions filtering system did not work in all temperatures, but denies wrongdoing

Renault has recalled more than 15,000 diesel cars after an admission that its emissions filtering system does not work in all temperatures.

The French carmaker denied any wrongdoing and said there was no "defeat device" of the kind Volkswagen used to cheat emissions tests, but acknowledged there was a difference between its test results and actual pollution.
