Do you ever feel like your BMW’s fuel gauge has a mind of its own? Maybe one moment it reads full, and the next, it’s dangerously close to empty. If this sounds familiar, then you are not mistaken, your fuel gauge may be problematic. The fuel gauge is one of the most important parts of your car. It provides a very near estimate of how much fuel you have left so as not to get stuck in the middle of the road. When it starts acting up, it can leave you in a confused state as you begin to wonder how far you will be able to drive with the fuel in your tank. Here is a closer look at the symptoms a faulty fuel gauge may display and what you should do about it.
Symptoms That Tell You Your BMW’s Fuel Gauge Is Off
- Inaccurate Readings: The clearest symptoms of a failing fuel gauge are erratic or inaccurate readings of the fuel level. For instance, the gauge may read that the tank is full when you are driving and it may read empty after you just refueled the car.
- Stuck Fuel Gauge Needle: Is the needle on your fuel gauge stuck in one position? This is usually as a result of a problem with the sending unit or with the gauge that is used. A needle that gets stuck will leave you wondering how much fuel is actually in your tank.
- Rapidly Fluctuating Fuel Levels: If the needle of the fuel gauge is not steady, and is jumping up and down like a kangaroo then it is time to get the car checked. This is an issue that can be quite annoying because it almost makes it impossible for you to gauge your fuel levels.
- Fuel Light Staying On or Off: The low fuel warning light was designed to illuminate to let you know that your fuel levels are low. But a faulty fuel gauge can make the light remain on when the tank is full—or fail to light up when the tank is almost empty.
- Strange Behavior After Refueling: Another sign is if your fuel gauge doesn’t change after you fill up your car’s tank. You may also find that the gauge remains at empty or does not reach the appropriate level.
What Should You Do If Your BMW’s Fuel Gauge Is Malfunctioning?
- Check the Fuses: Find out where the fuse is situated in your BMW and learn which of the fuse is responsible for the fuel gauge or fuel system. Check the fuse for any signs of burn or damage with your eyes or by touching it. Replace it if necessary, just make sure that you have the right fuse amperage available.
- Use an OBD-II Scanner: Plug in an OBD-II scanner to your BMW’s diagnostic port to look for fault codes that pertain to the fuel gauge, or fuel system. These codes may be associated with problems in the sensors, the fuel level sender or the ECU.
- Inspect the Instrument Cluster: If the fuel gauge acts funny, or if it does not move at all even with a good sending unit and wiring, the problem could be with the instrument cluster. Bring it to a technician for diagnostics and/or fixing.
- Check for Fuel Tank Issues: Check visually for signs of damage on the fuel tank because dents or deformation will put pressure on the float arm of the sending unit. In some cases, a float may be significantly damaged and it may require fixing or replacement.
- Consult a Professional: In case the above steps fail to work, you should take your BMW to an accredited mechanic. They can carry out enhanced scanning and then fix the system, or replace parts of it to have the fuel gauge working correctly again.
