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.
To effectively diagnose the gas smell in your 2021 Land Rover Range Rover, start with a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Begin by inspecting the area under your vehicle for any visible leaks in the fuel system, as this can quickly reveal the source of the odor. Next, ensure that the fuel cap is securely tightened, as a loose or damaged cap can allow fuel vapors to escape. Following this, examine the fuel lines for any signs of cracks or damage, as these can also contribute to fuel odors. If the smell persists, consider checking the fuel injectors, as faulty injectors may be leaking fuel. Additionally, inspect the charcoal canister, which is part of the evaporative emissions control system, for any signs of damage or leaks. If you are unable to identify the source of the gas smell after these checks, it is advisable to consult a qualified mechanic for a thorough inspection. This step-by-step diagnostic approach not only helps in pinpointing the issue but also ensures that you address any potential safety hazards associated with fuel leaks.
If you're detecting a gas smell in your 2021 Land Rover Range Rover, it's crucial to investigate the underlying causes to ensure both safety and vehicle performance. One of the most common culprits is a fuel leak, which can stem from damaged fuel lines, faulty fuel injectors, or issues with the fuel tank itself. Additionally, a loose gas cap can lead to fuel vapors escaping, so it's wise to check that it is securely fastened after refueling. Another potential source of the odor could be a malfunction in the evaporative emissions system, which is designed to manage fuel vapor release. Furthermore, an exhaust system leak, such as a crack in the exhaust pipe or a failing catalytic converter, may allow gas fumes to infiltrate the cabin. Lastly, engine misfires can result in incomplete fuel combustion, contributing to the gas smell. If you encounter this issue, it's advisable to conduct a thorough inspection or consult a qualified mechanic to pinpoint and rectify the problem effectively.
Addressing a gas smell in your 2021 Land Rover Range Rover is not just a matter of inconvenience; it is a pressing safety concern that requires immediate attention. Gas leaks can lead to catastrophic outcomes, including the risk of fire, which endangers not only your life but also the lives of others nearby. Moreover, the inhalation of gas fumes poses serious health risks, with symptoms ranging from mild discomfort to severe health complications with prolonged exposure. Ignoring this warning sign can also result in further damage to your vehicle, leading to expensive repairs down the line. Therefore, if you detect a gas smell, it is imperative to act swiftly—either by conducting a thorough inspection yourself or seeking professional assistance—to ensure your safety and the longevity of your vehicle.
