When it comes to fun, powerful, budget-friendly cars, the MINI always comes to mind. MINIs offer their drivers a combination of unique design and incredible performance. With that, MINIs also develop faults after an extended period of use. One of such parts susceptible to faults after is the fuel gauge.
The fuel gauge may fail over time, giving inaccurate or no reading due to faulty sending units, electrical issues, or an issue with the indicator. Discussed below are symptoms and causes of a faulty fuel gauge in your MINI.
The Fuel Gauge
The fuel gauge is one of the most important parts of any vehicle. To a large extent, this gauge determines whether you reach your destination or become stranded on the road. This simple yet essential instrument helps monitor your fuel level and inform the driver through the fuel gauge located on the dashboard. This way, you can know the right time to hit the gas station for a refill.
For better understanding, the fuel gauge consists of two parts:
- The sending unit
- The indicator
The sending unit located in the fuel tank operates using an arm, float, and resistor. The float and arm work in sync with the fuel level so that when levels are low, the float drops, changing the resistance in the potentiometer. This will lead to a low current being sent to the gauge, which causes the gauge to display close to empty signals.
The Indicator unit located on the dashboard functions by displaying the type of electric current received from the sending unit. Signals are usually interpreted to reflect between “E” empty tank or “F” full tank. When your fuel levels are low, the signal tilts towards “E”; conversely, it moves towards “F” when the fuel levels are high.
How do you Identify a Faulty Fuel Gauge?
Like most vehicles, your MINI is bound to experience certain faults with its internal components, the fuel gauge is no exemption. When this happens, you ought to be able to Identify this fault effectively to prevent further issues. Here are some signs to watch for when dealing with a faulty fuel gauge in your Mini.
- Faulty indicator: This is the most common indicator of a faulty fuel gauge. When your indicator is faulty, the needle is usually stuck at one end either at “E” empty or “F” full. This status does not change irrespective of the amount of fuel in the tank. The needle can also move erratically from one angle to the other.
- Check Engine Light: With a faulty indicator, your check engine may activate and stay on. While this could have resulted from other mechanical faults, a faulty fuel gauge cannot be ruled out. If you notice any of these signs in your Mini, then you possibly have a faulty fuel gauge.
Reasons Behind the Faulty Fuel Gauge In Your Mini
- Faulty sending Units: This is usually the first place to look for an issue. When the sending units become defective, it becomes unable to carry out a correct reading of the fuel level in the tank. This develops a negative spiral effect by sending incorrect signals to the indicator, which in turn gives a false reading.
- Electrical Issues: The wiring in your MINI plays a significant role in how well the fuel gauge functions. It transports signals from the sending unit to the other components. These wires, however, can get damaged or disconnected over time by factors like coolant leaks, pest infestation, rain, etc. When this happens, the wiring might corrode or loosen, interfering with the signal. As a result, false signals are sent to the indicator.
- Issues within the indicator: Several problems may arise within the indicator, ranging from short circuits to blown fuses. The instrument cluster can also malfunction.
