Re: Fuel gauge problem
Hi there and welcome.
Its a sad fact of life that £5 or £10 doesn't buy much fuel these days, so it may not really be a guage inaccuracy as such.
The only way to completely know how much fuel is in the tank is to brim it (I always re-set the trip recorder & computer at the same time), and see how that level of fuel is recorded by the guage.
The fuel light is intended to illuminate once the fuel level drops below a certain limit, so if the amount you add doesn't bring the overall level above that threshold, the light will still remain on.
I would fill the tank, then report your findings, at least you will be eliminating the risk and embarassment of running completely out of fuel.
This job should never be complete - the day I think I've done it all, is the day I resign.
