With the BS6 norms kicking in, Volkswagen India has done some major restructuring to its current lineup. While the automaker has launched the updated Polo and Vento with the 1.0-litre petrol motor, the diesel versions have been discontinued. Similarly, the German auto giant is all set to boot the Tiguan diesel from its Indian line-up by the end of this month, carandbike can confirm. The five-seater Volkswagen Tiguan diesel won't be upgraded to meet the BS6 emission norms that kick-in from April 2020.
