petrol gauge and trip comp problem!

[Double Deux Dan]

when i got into my car this morning to take the wife to work my car was running as close to normal as a clio will ever get. after doing around 5 miles my petrol light came on and the trip computer said i had no miles left before i needed to fill up (remaing miles on current amount of fuel). but, i had put 10 quids worth of go go juice in the night before which my fuel gauge was still reading (pretty much quarter of a tank) at the same time my light came on and the comp was lying to me!! any ideas what this could have been caused by or if anyone has had this problem and how they fixed it!

this car is doin my head in, there is always somethin wrong wit it!!!!! BO**OCKS to reg vardy!!!!!!

Happened to me last week actually, just added a little petrol and it sorted it. I think it's just the sensor, no biggy.
