Technical question, vehicle is 1996 D90 300Tdi. The signal from the fuel gauge sender is obviously variable with the fuel height, and goes up and down according to how the fuel sloshes about in the tank. The fuel gauge, however, should show a steady reading. The signal is somehow damped. Is this in the sender or in the gauge? Asking because I have recently fitted a new fuel sender which worked perfectly for 3 months. Yesterday I let the tank get very low (right on the lower edge of the red sector) and then brimmed it. As I drove away from the petrol station, the needle was waving about like a drunken sailor between about half and full. Today it is the same. It will stay steady on F for a while (done under 20 miles on full tank) and then drop to 1/2 and start waving around again. Fault in sender or gauge? Possible link with letting tank go empty and then filling to brim? Any help appreciated.
