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 2014 Land Rover LR4, it's essential to adopt a systematic diagnostic approach to identify the root cause effectively. Begin by checking the gas cap, as a loose or damaged cap is often the simplest and most common culprit behind fuel odors. If the gas cap is secure, inspect the fuel system for any visible leaks or signs of malfunction, as issues here can lead to significant gas smells. Next, examine the emissions control system, particularly the catalytic converter, since problems in this area can also contribute to fuel odors. Additionally, monitor your oil levels and inspect for any burning oil, which can create a distinct smell that may be confused with gasoline. Don’t overlook the fuel rail and injectors; any leaks or damage here can release gas fumes into the engine compartment. Lastly, evaluate the DMTL system, which is crucial for maintaining fuel system pressure and detecting leaks. If these steps do not resolve the issue, it may be time to consult a professional mechanic who specializes in Land Rover vehicles for a comprehensive inspection and repair. By following this methodical approach, you can effectively diagnose and address the gas smell in your vehicle.
If your 2014 Land Rover LR4 has developed a gas smell, it’s essential to identify the source to ensure safety and prevent further damage. One of the most common culprits is a loose or damaged gas cap, which can easily be checked and tightened or replaced if necessary. Additionally, inspect the fuel system for leaks, particularly around the fuel rail and injectors, as these areas are prone to wear and can lead to fuel escaping. Another area to consider is the emissions control system; a failing catalytic converter may not only produce unusual odors but could also trigger the check engine light, indicating a need for further investigation. Lastly, be aware of any recalls related to the gas flange, as these may require specific repairs from a dealership. While some of these checks can be performed at home, consulting a qualified mechanic is advisable for a thorough diagnosis and to ensure that any repairs are conducted safely and effectively.
Addressing the gas smell in your 2014 Land Rover LR4 is not just a matter of comfort; it is a critical safety concern that requires immediate attention. The presence of gasoline fumes can pose serious health risks, including respiratory issues from prolonged exposure. More importantly, a gas smell often indicates a leak or malfunction within the fuel system, which could lead to dangerous situations such as fires or explosions. Ignoring this warning sign can escalate into more severe mechanical problems, resulting in expensive repairs that could have been avoided with timely intervention. Therefore, it is essential to investigate and resolve any gas odors in your vehicle as soon as they are detected, ensuring both your safety and the longevity of your Land Rover.
