    Dear Mr. Tsukasa Azuma,
    I have a Nissan Terrano Petrol Propelled VG33 Engine. I am experiencing problems with fuel gauge, that rises to full tank or three quarter tank even when I have just put in a quarter tank of fuel, afterwards it drops to where it is supposed to be. What could be causing this?
    Lately, am also having a problem with the odometer reading. When I switch the Engine, it will not come on/show that mileage. It will be blank , but after driving or whilst driving, it would come on but the reading would be behind. When I park, and later on start the car, it would show the latest mileage by updating or adding up to the correct mileage covered. This is the routine am facing. It is on and off. When it switches whilst driving, you expect to see a movement for every distance/km covered, but it will just be static without movement until after sometime when it would move to what could be the correct reading? What is the cause? It it electrical or mechanical? What can i do ?
