sounds like the tank sender unit in the fuel tank

cheers gteyes, i thought the same, do you know if it is a common fault?

have replaced a few if you know your way around cars you can test it under the back seat on the drivers side the a black cover with 3 philps screws on it under this is the supply pump and gauge you can diconnect the plug and turn on the ignition and see if the needle moves if it stills goes to half way proplem might be in the dash insert if it stays a 0 it a prety safe bet that the sender unit is at fault and just depending on your skill you could remove the unit and move the float up and and check the resistance as far as i recall its just over 2 omhs when full and it should go down smothly as the float goes down but as you said its under wty let them worry about it

had car in dealers today and they said sender unit is ok, but they had to recalibrate tank or something like that, anyone heard of this before?? and they tried to charge me for this but said if they replaced sender unit it would be covered by warrenty,
