MINI Faulty Fuel Gauge

The Mini is a great vehicle, and it delivers on the fuel efficiency promises that they make. Their unique, compact design paired with performance make them a highly sought-after vehicle. These small cars do not have any unnecessary parts added on to them, which makes regular vehicle maintenance critical. Minis get great gas mileage, so when the fuel gauge malfunctions that can take away from the reliability of the vehicle.

Fuel gauge issues happen in all types of vehicles, but unfortunately they seem to be a reoccurring issue on the Mini. Having a problem with the fuel system can be confusing, and could possibly lead to an accident that could jeopardize your safety.

Symptoms of a Faulty Fuel Gauge

Knowing what to watch out for will help you know if your fuel gauge is malfunctioning. Here are two common symptoms that you need to look out for:

Gas Mileage

Having a faulty fuel gauge can cause you to run out of gas, leaving you stranded on the side of the road. Running out of gas on a busy road can also increase your chances of an accident. To avoid this ever happening, it is a good practice to monitor your gas mileage. If your gas mileage changes significantly you might have a faulty fuel gauge.

Strange Gauge Readings

If your fuel gauge has an issue, the system will start acting differently. It is common for the gauge to get stuck on full or empty. It can also act erratically. In some cases, it will become stuck. While driving a bump in the road can free it, causing it to go back to normal, it will likely get stuck again. In the case that it shows empty, there is usually a total failure in one of the parts.

Two Common Causes of Faulty Fuel Gauge Readings

Defective Fuel Sending Unit

The fuel sending unit reads the fuel level in your tank and sends the information to the fuel gauge. This unit is located inside the tank and needs special equipment to perform the diagnostics. The unit is made up of an arm, float, and a resistor. The float floats on the fuel surface inside of the tank. As your fuel level drops or your add fuel into your tank, the arm and float will shift. The resistor gathers the information and sends it to the fuel gauge.

Old and Worn Out Wiring

In older cars, wiring can be an issue. Old wires can wear out and become corroded. This can cause improper information to be sent to the fuel gauge. There can be a lot of potential sources causing the dilemma. Having someone that has the expertise in knowing how to find these types of issues is key to fixing the problem. In some cases, the wiring can be cleaned or tightened, but in others, it needs to be replaced.

Fuel gauges are a valuable resource to a driver. Not knowing the correct fuel level in your tank can be aggravating and dangerous. You could easily run out of fuel and become stranded. If your Mini has a faulty fuel gauge, it is important to have it fixed as soon as you can.
