Re: 147 1.6 Erratic fuel gauge
sorry, reread your post and you do have a problem. next time it happens bang your fist above the gauge. if that makes it correct itself then the problem is either the connector behind the gauge or a dry joint on the PCB for the gauge (not uncommon). if banging your fist doesnt help then you need to attack the fuel gauge sender unit in the tank, which can be accessed easily if you remove the fuel pump access panel in the boot. i would try wiggling the connector on your sender unit rather than replacing it.
