What is the reason for the sudden fluctuation of the fuel gauge needle in the Volkswagen CC?
1 Answers
Fluctuations in the fuel gauge during the break-in period of a new car are common. However, if an older vehicle experiences this issue, it may indicate a problem with the fuel system. Below are specific explanations regarding fuel gauge malfunctions: 1. The primary cause of an inaccurate fuel gauge is a faulty fuel level sensor. If the gauge suddenly drops to zero, it is almost entirely dependent on the fuel level sensor, meaning the needle is merely a visual representation of the sensor's readings. 2. If the vehicle has been in use for 2-3 years and this issue begins to occur, it is generally due to contamination of the fuel level sensor, which requires timely cleaning to resolve. Since gasoline contains many impurities, the sensor, which is constantly submerged in fuel, can become contaminated over time, directly affecting the accuracy of the readings. 3. For vehicles that have been in use for over 5 years, an inaccurate fuel gauge reading may be due to physical wear and tear on the fuel level sensor, rendering it unable to function properly. In this case, replacement of the sensor is necessary.
