Fuel gauge fault 2010 RRS

Hi.
I have a 2010 RRS TDV6. It has half a tank of diesel in it when suddenly the low fuel warning pops up and the gauge says empty!!. Tried the usual cancelling of the warning and turning it on and off but still says empty.
I’ve had a few issues with other sensors in the past which have been resolved.
Has anyone else had this issue and have any idea how to fix it. Cost?
Alternatively does anyone know where I can find the wiring so I can check the connection etc before I have to take it to a garage.

Thanks

It tends to be the gauge in the tank causing this ..the wiring decays to the sensor ..if I recall it's around £90-£100 for the sensor

Thanks for the help. Hopefully it won’t be anything too costly but £100 plus labour shouldn’t be too bad
