04 1.2 Fuel gauge not working - Rattle
Friends clio has a none functioning fuel gauge, it was on empty this morning so she put some fuel in but it was still showing as empty and the warning light is on. I've had a good look round and there is no signs of any leaks etc.

I suspect this is an electrical problem from the fuel gauge sender to the digital display on the dash is this a common problem with the Clio and is it a CANBUS system?
