Anybody had this problem...?

I took her out for a spin last night and the fuel gauge started beeping at me saying I only had 1 litre of fuel left. There's no way 14 litres just vannished in the space of a couple of miles...

I went to the petrol station and put some fuel in and the gauge has failed to recognise that I have put any in. It just beeps at me saying I've only got 1 litre left still. I have to press both reset buttons to stop the beeping.

What's happened? Will it reset if I fill up again in a couple of days...

Any ideas would be appreciated as I dont want to play the guessing game.

Cheers

The fuel sensor is pretty inaccurate..

I find that the only good time to read the fuel is when the car has come to a stop on a level surface for a minute.

On normal driving I just look down and read the value over a few minutes and work out an average in my head. I have started a journey with 16L and a few miles get the warning - I remember because it was in a long Motorway queue with no hope of gettin g off for a few miles - after that I make sure I always have 20L+ in the tank when going anywhere..

Cheers,

I have filled the tank to the brim and am still getting beeped at with 1 litre left. Is the fuel sensor knackered because I let the fuel get too low or something???

Very strange... and the beeping is doing my head in everytime I get in!!!

My Tuscan fuel gauge stopped working at a recent track day - the connector to the sender on top of the tank popped off after a spin. In that case the gauge read zero litres. Given that the instrument pack is very different between a Tuscan and T350/Tamora, 1 litre might be your default minimum reading, and you might just have either a broken sender or a broken connection. Easy enough to check the connection on top of the tank by removing some of the boot carpet. Otherwise check the resistance of the sender; I believe it should increase as the fuel level increases.

I had a problem with my gauge a couple of years ago, it might be worth checking what i did?
If you are not that mechanically minded, bring it round to me and i will look for you, i live in Stubbington.

I have a problem with my fuel gauge too. When I first start the car it reads very low fuel(1-4l) and then it will suddenly read 190l (which would be nice but I know isn't true). Also within the first 15 mins of driving the car it with come up with fuel sensor error. Does this all mean just a replacement sensor? If so where can I get one from?

Thanks Guys,

I had a fiddle with the connector (took it off and put it back on again) but this didn't do anything.

Thanks for the offer Tony. Not seen you around...
I've got to book the car in for an MOT next week so I'll get Racing Green to see if they can fix it.

Cheers

I know the Sagaris (and probably T350) reads 1L when there is no fuel in the tank, I suspect it would read zero if the sensor didn`t work at all..

Crazy car! It's fixed itself???

Probably the best TVR in the world... One that repairs itself.

I wonder how long it will stay fixed though confused
