Brothers, here is the story..
2 days ago my xli didnt start in the morning - car was on CNG overnight so i changed it to petrol but it still didnt. Pushed the car in street and it got started on petrol... after riding for sometime, the engine check light went on - this happened for the first time in 3 years since i bought this car. The light kept on till I reached office. In the lunch hour, I started the car on CNG, it started okay and the engine light was off. However now the light in the in-dash digital clock has gone off. Clock works fine though. It remains so as of today. Battery is factory fitted.
Today the car started with taking more self than before... so i guess, battery could be weak. But what about the engine check light and the now permanently OFF digital clock light.
