I got my XUV PUC yesterday,for 150 /- near my place in KANPUR(UP).Its valid for one year. Its 80 Rs for 6 months.
That man kept on pressing the accelerator and increasing the RPM till 4000,to get the readings.This never happened so far.In petrol cars,it was always taken while the car was idling,at 750 RPM.
Maybe in diesel they are intending to open the EGR valve for the readings.
