How do you reset the fuel gauge on a Mercedes?
The other is a connector in the driver’s side rear wheel well, where if you diconnect the harness with the ignition off, and you wait a couple of seconds, then the fuel gauge mechanism will be reset. Number one is more practical in my view..
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.
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.
Why does my gas gauge keep pegging full?
The gas gauge might interpret voltage feedback from a dead sender as FULL or EMPTY, consequently pegging the gauge no matter the actual fuel level. Circuit Problems can cause the gas gauge to stop functioning normally.

Is it possible for a fuel gauge to fail?
While gauges themselves can fail, generally the problems are found in wiring or the sending unit, rather than the gauge, so it’s best to rule out all the other possibilities before tackling the gauge itself. Tracking down fuel gauge issues can be a pain.

What causes a fuel gauge to read empty?
Another common symptom of a faulty fuel gauge sender is a gauge that is stuck on empty. If the float somehow breaks or becomes separated from the arm it may cause the fuel gauge to malfunction and become stuck on empty. A faulty resistor can also cause the gauge to read empty. 3. Fuel gauge stuck on full
When do you need to replace the fuel gauge sender?
If your fuel gauge behaves erratically or is stuck on full or empty, you may need to replace the fuel gauge sender. 1. Fuel gauge behaves erratically 2. Fuel gauge stuck on empty 3. Fuel gauge stuck on full The fuel gauge sender is a component that is found in the gas tank of most road going vehicles.
To repair this issue you must reset the fuel gauge.
- Turn the car off.
- Remove the fuse cover inside below the passenger side door.
- Pull the 15A blue fuse number F5.
- Check it and put it back in.
- Turn on car ignition and fuel gauge has been reset and should be working now.
Why is the fuel gauge on my car not working?
Some fuel gauges have an analog display while others have a digital or liquid crystal display. Electronic and software malfunctions may cause the fuel gauge in your automobile to inaccurately measure or display the amount of fuel remaining in the gas tank. If this happens, reset your fuel gauge.
How is the fuel gauge connected to the tank?
There is also a float-like instrument inside your gas tank that is connected to a rheostat (or resistance-sweep…think of a volume knob on a stereo) which communicates directly to the fuel gauge.
What should I do if my gauge does not respond?
If after “grounding out” the sender the gauge reads Full, then the problem is with the sender; if the gauge does not respond then the problem is with the gauge. If the problem is with the gauge or its wiring, start by performing a continuity check of the gauge wiring.
