I have a blinking odo, blinking temperature reading on the AC panel. I have had this issue intermittently but have always ignored it. I am experiencing a new problem since the last 1 month. When I start the car, the rolling code light comes on (the car with a lock on it sign), the display shows "Low fuel warning" even though I have 90% tank full. I stop and restart the car and its gone. Sometimes I have to start the car twice for the "rolling code" light to go off. I showed the problem to RS Motors (ASS in Mumbai). They were of the opinion that it could be due to the weak battery. They checked the battery and found it ok. However, they added some distilled water as the level had gone down. The problem went away for a week and now it is back. Should I go for a battery replacement? My car is 2.5 years old.
