BMW E46 fuel gauge on yellow
If the fuel gauge on the BMW E46 turns yellow, there is little gasoline in the tank and you have to fill up, then everything should be back to normal. Sometimes the display doesn't change even after you've filled up. Here's what you can do in such a case.
Help when the fuel gauge is yellow
- It is annoying if the fuel gauge is yellow and the range is not displayed correctly, but you can also drive without this aid. Fill up with fuel, make a note of the odometer reading and drive two-thirds of the kilometers that you can usually cover on one tank of fuel. Then fill up again. So you can drive with the problem for a long time.
- If you are not familiar with the consumption of your car or if you do not know how far you can get on a filling, refuel after 300 kilometers. So you can determine the consumption quite well in order to calculate the range.
- Since the fuel gauge of the BMW E46 is only a computer, you can often reset it to show normal values again. Disconnect the car from the battery for at least 15 minutes. Some drivers report that they had to disconnect the battery overnight before the fuel gauge returned to normal.
