Thanks for the replies guys. I will give you some basic facts for better information. The kit is LR and it is mostly used on cng. It is both n cng and petrol. Last ight I took the car to abbottabad via motorway. Changed the battery today and got a new dry one from hankook. The light came on today in the morning before battery change. When the onboard computer was reset while replacing the battery, the light was gone but it turned on again.
The car does not shut down while driving. It runs fine.
