Petrol Warning Light Help

[Andy.1.2-16v]

Hello all

The petrol warning light on my Clio used to come on when the petrol needle hit the red line but just recently it has started coming on as soon as the petrol gauge needle hits the last white line before the red line (I think it's the 8th of a tank marker).

Anyone else had this happen, is it a dodgy gauge or a dodgy sensor causing the light to come one.

Thanks muchly in advance

the tank sensor has essentially 2 sensors in it. one for the gauge (float and varible resistor type) and one for the light. they both may not be accurate at any one time.

IMHO running the tank down that low sucks debris into the filter that has accumilated over the years and that aint very good.

anyway don't rely on the light or the guage telling the whole truth in any case, no fun running out of petrol
