What is the reason for the unresponsive fuel gauge in a BMW 5 Series?
1 Answers
An unresponsive fuel gauge in a BMW 5 Series may be due to a faulty fuel gauge sensor. Below are the specific reasons and solutions: 1. Specific reason: The fuel gauge needle remains stuck at a certain position and does not move, or even shows an increase in the displayed value after driving a certain distance. This phenomenon occurs because the fuel gauge sensor is malfunctioning. The fuel level sensor detects the position of fuel in the container by measuring the change in capacitance between the sensor housing and the sensing electrode caused by the fuel entering the container, and converts this change into a current variation. 2. Solution: Visit a 4S shop to have a professional technician replace the sensor.
