How to Fix the Fuel Gauge Not Displaying on a Mercedes-Benz C200?

You can try turning off the vehicle, then disconnecting the negative terminal of the battery, waiting for 3-5 minutes, and reconnecting the negative terminal of the battery. This process allows the vehicle's computer to reboot, which can resolve some software-related issues.
When dealing with luxury car issues like a non-illuminating fuel gauge in a Mercedes-Benz C200, don't rush to drive. Start by checking the simple things first—the fuse. Open the fuse box and locate the one related to the instrument cluster; its position is marked in the user manual. If the fuse is blown, replace it with a spare. If the fuse is intact, the issue might be a faulty fuel level sensor, which is submerged in fuel inside the tank and could be stuck or short-circuited. Professional equipment is needed to remove and inspect it. Mercedes' electronic systems are complex, and tampering without care can damage the wiring. It's best to use an OBD scanner to read error codes and determine whether the problem lies with the instrument cluster or the sensor. Additionally, loose wiring connections can also cause display abnormalities—check under the hood along the wiring harness for any damage. Don't delay addressing such issues; an inaccurate fuel gauge can leave you stranded with an unexpected stall, which is both dangerous and costly. Schedule an appointment with a Mercedes specialist as soon as possible for a comprehensive check-up, and consider servicing the fuel system while you're at it. Safety first—always double-check your fuel level before driving.
