fuel gauge issue

hi, Has anyone experienced issues with their fuel gauge. Car is Mk 3 Vrs diesel, 2016 model. Last weekend it was very low on fuel and so i put £10 in it (came to top of red with a range reading of 55miles) till i could et to my usual filling station where i filled it fully. when driving after filling it i noticed that the fuel gauge hadnt moved form the end of the red range and still showed a range of 55 miles to empty. After 50 miles the car has shown 0 miles range and has done so since, having now covered 370 miles. Today i have had the sender out of the tank, checked the connections all okay and run a full scan on the car which has shown no issues at all. can anyone offer help or assistance. thanks
