How does the fuel gauge work on a Mercedes Benz?
I would check the fuel level sensor that Chris mentioned. The sensor is a variable resistance inversely proportional to the level of fuel and ranges from roughly 5 ohms (empty) to 70 ohms (full). You access the contacts of the sensor by removing the cover shown in the picture.
How are level sensors used in a Mercedes?
Input from these sensors is used by the airmatic suspension to automatically self-level the vehicle height based on the vehicle load. Mercedes level sensors determine the position of the airmatic strut, which determines the vehicle’s load. Level sensors are also known as suspension ride height sensor.
What does a Mercedes ride height sensor do?
Mercedes level sensors determine the position of the airmatic strut, which determines the vehicle’s load. Level sensors are also known as suspension ride height sensor. A level sensor should not be confused with the axle damping valve unit. How to Replace Mercedes-Benz Ride Level Sensor?
Why is my fuel gauge not reading correctly?
If your fuel gauge is not reading accurately you CAN fix this yourself and save $$$$$! If your fuel level gauge is not reading accurately or the needle jumps around and or your car’s low fuel warning light does not comes on, it is usually a problem with the tubular sending unit in the fuel tank.

How to test and replace a fuel level sensor?
How to test and replace a fuel level sensor. Because it’s an in-tank fuel pump, the hardest job is removing the fuel pump from the vehicle. Doing this test can help you pinpoint why the fuel gauge is not working. If this sensor is indeed working on your vehicle, then check the fuel gauge itself. This specific vehicle is a 2010 Subaru Impreza.

Why does the low fuel warning light not come on?
If your fuel level gauge is not reading accurately or the needle jumps around and or your car’s low fuel warning light does not comes on, it is usually a problem with the tubular sending unit in the fuel tank. If you don’t fix it, you may run out of fuel some day when the gauge is reading a quarter of a tank!
What should I do if my gas gauge is not working?
Note that some self-test steps may stop the gas gauge at 1/4, 1/2, and 3/4, as well. Fuel sender test. The fuel sender test should be conducted when the tank is lower than HALF, to prevent fuel splashing. Start by making sure the plug is clean, dry, and free of corrosion. Make sure the pins are straight and that the connector is fully seated.
What happens to the gas gauge when the circuit is shorted?
If the internal circuit is faulty, the gas gauge may only function in one section, such as between HALF and FULL or between EMPTY and HALF. If the internal circuits are shorted, they may peg to FULL or EMPTY. If the circuit is open, the gas gauge will likely sit at EMPTY and never move.
What kind of car has no fuel gauge?
No mather how much gas i put in it, the fuel gauge will not move from “empty” with the reserve light on in cluster… Where sould i start to located this problem? Fuse is Ok. MB SL600, MB 380SE, Suzuki Grand Vitara, 38′ Chris-Craft, Volvo V70XC, and my own two feet…
Why is the fuel gauge empty on my 2001 ML320?
MY 2001 ML320 exhibited the fuel gauge problem today. I filled fuel this morning on my way to work. Soon thereafter, the fuel gauge showed that it was empty despite a complete fillup.
Why is the speedometer on my Mercedes not working?
An instrument cluster ain’t cheap!! Upon checking further—-all four speed sensors would have to fail for the speedo IC computer to read “0”. Additionally the traction control modules are the modules that provide the rpm data for the IC via the CAN. Therefore it could mean that the data is not getting to the IC.
What is the resistance of the fuel gauge?
The sensor is a variable resistance inversely proportional to the level of fuel and ranges from roughly 5 ohms (empty) to 70 ohms (full). You access the contacts of the sensor by removing the cover shown in the picture.
