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. These conditions may be intermittent, or constant and worsen over time. As the issue progresses, the engine may being to stall immediately after starting, fail to start, hesitate under throttle, or stall at particular angles on hills.

A fuel tank leak may also cause difficulty starting the engine, a rough idle, and poor fuel mileage. When a fuel tank is simply corroded to the point of failure, the exterior tank condition rarely shows damage. The inside of the fuel tank will be rusted or corroded, and rust flakes or other debris may be floating in the fuel.
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 faced with a gas smell in your 2003 Mercedes-Benz CLK55 AMG, it's essential to adopt a systematic diagnostic approach to identify the root cause. Start with a thorough visual inspection of the fuel system, focusing on the fuel tank, lines, and injectors for any signs of leaks or damage. Pay close attention to the area beneath the vehicle for wet spots or puddles, which may indicate a fuel leak. If the check engine light is illuminated, utilizing an OBD-II scanner can provide valuable error codes that may help pinpoint the issue. Additionally, consider the condition of the evaporative emissions system, as leaks or malfunctions here can also contribute to a gas smell. If your initial checks do not reveal the source of the problem, it may be prudent to consult a professional mechanic for a comprehensive evaluation. By following this structured approach, you can effectively diagnose and address the gas smell in your vehicle, ensuring both safety and performance.

A common issue could be a faulty or improperly secured gas cap, which can allow fuel vapors to escape, creating a noticeable odor. Additionally, you should consider the possibility of fuel system problems, such as leaks or malfunctions, which can also lead to gas smells inside the cabin. The emissions control system may be another source; for example, a failing catalytic converter can contribute to the presence of gas odors. Lastly, inspect the seals on the fuel pump and sender units, as any leaks from these areas can result in a gas smell. By addressing these issues promptly, you can ensure a safer driving experience and prevent more severe complications in the future.
Addressing a gas smell in your 2003 Mercedes-Benz CLK55 AMG is not just a matter of convenience; it is a pressing safety concern that requires immediate attention. Gas leaks pose a significant risk of fire or explosion, particularly in the confined space of a vehicle, where even a small spark can lead to catastrophic consequences. Additionally, inhaling gas fumes can have serious health effects, including dizziness, headaches, and nausea, which can impair your ability to drive safely. Beyond the immediate dangers, neglecting a gas smell can lead to more extensive damage to your car's components, resulting in costly repairs down the line. Therefore, if you detect a gas smell, it is crucial to investigate the source and address the issue without delay to protect your safety, health, and the integrity of your vehicle.
