BMW Fuel Level Sending Unit diagram for 318ti

A fuel tank sending unit is a component located inside the fuel tank that measures the amount of fuel remaining and sends this information to the fuel gauge on the dashboard. The sending unit consists of a float, a metal rod, and a variable resistor. As the fuel level changes, the float moves up or down, causing the resistance to vary, which changes the signal sent to the gauge, indicating the fuel level.

• Inaccurate Fuel Gauge Readings: A failing sending unit often causes the fuel gauge to show incorrect fuel levels, such as always reading full, empty, or fluctuating unpredictably
• Stuck Fuel Gauge: If the float or sensor mechanism gets stuck, the fuel gauge may remain in one position, regardless of the actual fuel level
• Fuel Gauge Reads Empty with Fuel in Tank: A sending unit failure may cause the gauge to read empty, even though there is fuel remaining, leading to unnecessary refueling or inconvenience

About Genuine BMW

The original parts used by BMW to build your car are available as replacement parts under the “Genuine BMW” brand. When ordering a Genuine BMW part you are guaranteed to get the same part that you would pick up from your local dealerships part department. Genuine BMW parts have been built to BMW’s stringent standards and are the same quality of the original parts used to build your Ultimate Driving Machine.

You may not realize this, but the parts that make up your BMW are not necessarily manufactured by BMW. No cause for concern, as BMW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for BMW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine BMW parts box and find an OEM branded part inside, simply with the addition of a BMW logo.
