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.

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 dealing with a gas smell in your 2018 Land Rover Discovery, it's essential to adopt a systematic diagnostic approach to identify the underlying issue effectively. Start by inspecting the fuel system for any visible leaks, as a fuel leak is one of the most common causes of a gas odor. Check the fuel lines, connections, and the fuel tank for signs of damage or seepage. Next, ensure that the fuel cap is securely tightened and in good condition, as a faulty cap can allow gas vapors to escape. If these initial checks do not reveal the problem, examine the exhaust system for any leaks or unusual odors, which could indicate a malfunction. Utilizing a diagnostic scanner to check for error codes related to the fuel system or emissions components can provide further insights into potential issues. Additionally, performing a pressure test on the fuel system can help identify leaks or pressure regulation problems. Don’t overlook the evaporative emissions system; inspect its components for any signs of damage or malfunction. Finally, monitor your engine's performance for any signs of misfires or unusual exhaust emissions, as these can also contribute to a gas smell. By following this structured approach, you can effectively diagnose and address the source of the gas odor in your vehicle.
If you notice a gas smell in your 2018 Land Rover Discovery, it’s crucial to identify the underlying cause to ensure both safety and vehicle performance. One of the most common culprits is a fuel leak, which can occur in various components such as the fuel tank, fuel lines, or fuel injectors. Inspect these areas for any signs of leakage, such as wet spots or a strong gasoline odor. Additionally, a malfunctioning fuel injector may not atomize fuel properly, leading to an unpleasant smell. Another area to check is the evaporative emissions system, which manages fuel vapors; a faulty charcoal canister or leaks in this system can contribute to the issue. Don’t overlook the exhaust system either, as cracks or damage can allow exhaust fumes to enter the cabin. Lastly, be mindful of overfilling your gas tank, as this can cause gasoline to spill and create lingering odors. If you’re unable to pinpoint the source of the smell, it’s advisable to consult a qualified mechanic for a thorough inspection.
Addressing a gas smell in your 2018 Land Rover Discovery is not just a matter of inconvenience; it is a critical safety concern that demands immediate attention. The presence of gasoline fumes can indicate a leak, which poses a significant fire hazard that could endanger both you and others nearby. Moreover, inhaling these fumes can lead to serious health issues, including dizziness and nausea, which can impair your ability to drive safely. Ignoring this warning sign may also lead to more severe problems within your vehicle's fuel system, resulting in costly repairs down the line. Therefore, it is essential to act swiftly and investigate the source of the gas smell to protect your health and ensure the safety of your vehicle.
