i need help!! Basically when im driving along, my petrol gauge is showing that i have no petrol in there (i know i have got petrol in my tank as i only filled up yesterday and i haven't really done any driving). The gauge marker keeps going up and down (between the quarter of a tank and then to the empty white line. I had my MOT back in march and there was an advisory on there which was the Lambda sensor, can somebody please tell me if its the Lambda sensor which has gone so its making me think i have no petrol, or if it is another problem ???
Thanks people. Rep will be added :)
