2004 C2 fuel gauge fault

It sound like it is the fuel tank sender unit. This is was happens when it shorts out.

I have the same problem on my diesel citroen C2 could you tell me where to locate the sender unit please if a diesel has one ?

Filled up with diesel yet fuel gauge has dropped 2 units , cannot get anymore fuel in tank its full too top , why ? Fuel gauge gone down instead of showing full after I filled up with diesel

The float for the gas gauge is either stuck or is malfunctioning. You can try pulling it out and seeing if it is stuck ir being impeeded in some way.

You would need to check the fuel float sending unit and its circuit.

it does correct its self after a while but it is annoying when you first put your fuel in it does not register with it is there an easy way to sort it ie fill the tank up or do i go back to the garage I bought it from thankyou..

the only real fix is to replace the fuel tank sender unit !
