Can anyone help? Bought a second hand Logan a few days ago, and the fuel gauge will behave normally for a while then drop to halfway and flash. Can't find any info about it.

i thought that i share with u all a fuel gauge trick-shot 1. press and hold the reset trip meter button situated between the rpm meter and the miles per hour meter 2. insert key into ignition 3. switch the ignition key to the last position (DO NOT START THE ENGINE) 4. keep the button pressed...
