My fuel gauge warning light came on with 40 miles left on the clock. Just put 10 quids worth of petrol in and it hasnt budged. I know if i was to have put only a fiver in it wouldn't have registered but should have gone up enough to knock the warning off. Anyone any idea please, I'm thinking a diagnostic problem but dont want to shell out for the test if its something else

well in old "money" it's approx 1.6 galls--I'd put another£10 and maybe then start worrying :-)

From the manual

The fuel tank has a capacity of about 45 litres. The warning symbol ? in the instrument cluster lights up when the pointer reaches the reserve marking. There are now about 7 litres of fuel remaining in the tank.""

As above, £10 doesn't buy you much in the way of fuel now, shove another £10 in and the light will go out, brim the tank and it'll show full. Fuel senders aren't infallible or always accurate but they are reasonably reliable.
