Ok here I am once again 
So far have not driven the car that much, took it out only once since I bought last Sunday...(Will post the details of my first test drive of Liana later, comparing it with a 2001 City EXiS is kind of difficult
)
Anyways the issue i want to discuss with all of you. There is a slight problem it seems the CNG switch lights do not work. Yes it does tell you if you are driving on petrol of CNG...but the gauge lights - green - do not work.
So does a FF CNG kit have same kind of sensor as a Landi Renzo kit? of it is something very different?
Should I get it checked by a CNG mechanic or not? Don’t want to get into some sort of new problems (as other that the lights it is not giving me any trouble).
I have checked with the ex-owner he said that as it was not giving any problem and he used drive around 150km and get gas so ne never bothered to get this work done.
