Fuel Warning light misleading

Hi,
Coming back from a trip over the weekend I was on the M40 when the fuel warning light came on in my '04 Defender 90. The guage was on 1/4 full. No problem I thought, got at least another 30 miles in there, carry on to the next service area.

By the time I reached the service area the guage was on zero and I had been gently sweating for the last 9 or 10 miles (especially when stationary in a queue because of an accident). Filled it up and got just under 50 litres in. Now I think the tank is 60 litres so the light must have come on when I had about 15 litres left. Anyone else experienced that? Can I do something about it?

Thanks

Think yourself lucky. On my 1986 LR90 the fuel light randomly comes on anywhere after half a tank. Also the last half a tank on the guage is actually about 1/4 of the tank. Very confusing when i first bought it! Now i just carry 20ltr of deisel in the back just in case!

the gauge can be misleading as it's tied to the float ball in the tank, i believe. sometimes mine just screws up and shows it has 1/4 left and slowly it creeps up to the 1/2 mark when i start driving. wow!! the more i drive the more fuel the tank produces!! the float can start sticking at times and give you a wrong reading.

on the flip side, the fuel indicator comes on when there's 9litres or less of fuel in the tank. i believe this is a fixed indicator, so it comes on when there's 9litres of fuel in the tank regardless of where the gauge reads.

The light comes on when the guage reaches the 1/4 full mark, just like it did in my old '93 V8 110 that was nicked earlier this year. With the 90 it seems as though I had about 15 litres left. I just wondered if anyone else had experienced the same thing or whether its peculiar to my vehicle.

My fuel warning light is on permanently !!!

The light on my 2002 90 Td5 comes on at 11 litres left - on a flat piece of road.
The light will come on prematurely if going up a steep hill close to the 11 litres left, and will stay lit subsequently on a flat road unless I stop and switch off for whatever reason.
The light will now stay off until I get to 11l - or go up a hill again!
But I do trust it not to run me out of fuel.

My 200 tdi fuel light came on anywhere bout half tank or below so ran it till it started to splutter noted where that was on the gauge and removed the bulb from the dash board as it got on my wick

once mine has half a tank it comes on if i brake heavy on hill starts just about were it likes the joys of a landy 90

time for my first post .... likewise my 03 90csw come's on at the 15ltr marker.
i have now got in the habit of Zeroing the trip meter and re-filling at the 250 maker
this is usualy about 50ltrs (from now on the £50 POINT)

Dunno how many gallons/litres makes my light come on, but if it does ah'll just put more fuel in it. tend tae keep it above 1/4 tank at least
