India sought a response from Volkswagen AG after probes into four car models showed diesel-fuel emissions exceeding permissible limits, and variations in results between on-road tests and those done in laboratories.
Investigations into the Jetta, Vento, Polo and Audi A4 marques showed significant variations and about 314,000 vehicles are potentially affected, Ambuj Sharma, an additional secretary in India’s Heavy Industries Ministry, said in an interview in Mumbai. If cars have defeat devices that cheat tests, the matter would become criminal, he said.
