Sprinter fuel level sensor issue

I had a similar issue with my Mercedes. Not the same model, but close enough. The fuel gauge was acting erratically, and the check engine light was on. It was a faulty fuel level sensor. First, check the wiring going to the sensor. Make sure everything is properly connected and there's no corrosion. Also, if you can access the sensor itself, inspect it for any physical damage. Otherwise, maybe the level sensor itself has failed.

Where is the fuel level sensor located? Is it difficult to access? If I need to replace it, is it something I can do myself, or should I take it to a professional?

The fuel level sensor is typically located inside the fuel tank, as part of the fuel pump assembly. Accessing it usually involves dropping the fuel tank or accessing it from under a rear seat panel, depending on your vehicle's design. Given the symptoms, which includes engine stalls, and the fact that you already have an error code related to the sensor, it is best to take your car to a mechanic with experience in car electronics and the fuel system. A proper diagnosis with the right equipment is essential to confirm the problem and avoid unnecessary replacements. It could also be related to a defective car sensor, even if rare.

I took it to the shop, and you were spot on. The fuel level sensor was the culprit, even if it was just a defective fuse. They replaced it, cleared the code, and it's running perfectly now. Final bill was around 52€ Thanks for the guidance!
