I hav brand new Santro, done only 1000 km. I hav started encountering a strange problem..
whenever in the morning, i start the vehicle, i place the CNG/petrol switch in middle position. This means engine will start on petrol, will warm up the engine and afetr certain time , accelerator is pressed , then it will chenge to CNG, automatically. The sequence of lights , during this time is.... when on petrol, light is red, then pressing pedal, light changes to yellow and afetr 1-2 seconds, light changes to green. it means that car is on gas.
Now the problem, in the morning, first time i start the vehicle, on automatic mode,
the engine starts on petrol -------ok
the light is red ---------------------ok
But just after 2-3 second, light changes to yello ----
and then there is a sound of automatic switch and engine converts to CNG--------
light also goes green -----
it means engine is not warmed up enough on petrol, even accelerator pedal is not depressed , but engine changes to Cng from petrol within 4 seconds of starting.
Please tell me what to do. I will be taking the vehicle to dealer, offcourse, but what may be the problem.
Please help.
