The check engine light will illuminate any time there is a failed EVAP system test. This will be indicated by the various on-board diagnostics trouble codes that are stored in the vehicle's memory. Also, in some models, there may be a popping sound accompanying the check engine light, as the leak detection pump continuously attempts to pressurize the fuel tank. The canister may also cause difficulty starting the engine, a rough idle, and poor fuel mileage.
When the fuel filter begins to clog, the engine suffers from fuel starvation. This will cause a significant reduction in power and may also cause a misfire.

For most vehicles, the only symptom will be a check engine light or fuel tank filler cap light illuminating on the driver instrument cluster. This is to signal that there is an evaporative emissions (EVAP) leak. In some situations, the vehicle may take longer than normal to start, or, more rarely, the engine may not start at all. on-board diagnostic (OBD) trouble codes will refer to EVAP system failures such as a small or massive EVAP system leak. Lastly, the powertrain control module may notice a lean running condition, which could even lead to random and infrequent misfires.
When addressing a gas smell in your Mercedes-Benz 300SL, begin with a thorough visual inspection of the engine compartment, focusing on the low-pressure fuel line and any rubber hoses. Look for signs of wear, cracks, or leaks, particularly in colder temperatures when materials can become brittle. If you identify any damaged hoses, replacing them is a straightforward first step that can often resolve the issue. Next, check the hose clamps for tightness; loose clamps can lead to fuel leaks, so tightening them may eliminate the smell. If the problem persists, inspect the high-pressure fuel pump and surrounding areas for any signs of fuel seepage or exhaust issues. Remember, addressing these potential causes promptly is crucial not only for your safety but also for the vehicle's performance. If you are unable to locate the source of the gas smell after these initial checks, it may be time to consult a professional mechanic for a more in-depth diagnosis. By following this methodical approach, you can effectively troubleshoot and resolve the gas smell issue in your vehicle.
When you detect a gas smell in your Mercedes-Benz 300SL, it’s important to investigate several common problems that could be the source of the odor. One frequent issue is a faulty gas cap that fails to create a proper seal, allowing fuel vapors to escape. Additionally, leaking fuel lines or a malfunctioning EHA valve can contribute to the smell, often noticeable in the garage. Another area to check is the vapor canister and the overall fuel system, as fuel leaks or vapor escapes can lead to significant odors. Pay special attention to the low-pressure fuel hose connected to the high-pressure fuel pump, as this has been identified as a common source of gas smells, prompting extended warranties from Mercedes. If you notice a gas smell, look for any visible signs of leaks, such as pools or drips of gasoline, which indicate that immediate action is necessary. Addressing these issues not only helps eliminate the unpleasant odor but also ensures the safety and performance of your vehicle.
If your Mercedes-Benz 300SL emits a gas smell, it’s crucial to act swiftly to prevent hazardous situations and costly repairs. A gas odor can indicate a fuel leak, which poses a fire risk and can compromise the vehicle's performance. Start by checking the gas cap to ensure it is tightly sealed, as a loose cap can allow fumes to escape. Next, inspect the fuel system for any visible leaks in the lines or connections, as these can be common culprits. Additionally, examine the emissions control system for malfunctions that could contribute to the smell. Vapor escapes from the fuel system should also be investigated, as they can lead to persistent odors. Don’t overlook the exhaust system, as issues here can sometimes mimic fuel smells. If you’re unable to pinpoint the source of the odor or if the problem persists, it’s essential to seek professional assistance. Addressing these symptoms promptly not only ensures your safety but also helps maintain the integrity of your vehicle, preventing further complications down the line.
