The gas gauge light stays on even after filling the gas tank
I have 2000 ML 320. When gas is low the gas gauge light comes on, but after filling the tank the light stays on and the gauge needle stays at bottom. After some driving , when 1/4 of tank of gas is used, the gauge light disappears and the gauge moves to 3/4 full position. This happens every time gas is empty and when the tank is filled. Does n ay one has experineced this issue? any comments?
