Fuel level sensor

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

The fuel tank contains two fuel level sensors. Each fuel level sensor sends a signal indicating the amount of fuel in the tank. A value is obtained by adding the two signals. The fuel level sensors are connected to the junction box electronics (JBE) or on the Body Domain Controller (BDC). The signal is transmitted to the instrument cluster on the PT-CAN.

NOTE: The left-hand fuel level sensor cannot be replaced separately. No applicable for F15, F16, F85, F86.
