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 diagnosing a gas smell in your 2017 BMW 650i xDrive, it's essential to adopt a systematic approach that prioritizes simpler checks before moving on to more complex diagnostics. Start by inspecting the area beneath your vehicle for any visible leaks, as puddles or drips of gasoline can indicate a fuel system issue. Next, ensure that the fuel cap is securely tightened, as a loose or damaged cap can allow gas odors to escape. Following this, examine the fuel lines for any signs of cracks or damage, as these can lead to leaks. It's also wise to check the fuel injectors, as faulty injectors may contribute to gas smells; if you're unsure, consider having a mechanic evaluate them. Additionally, inspect the fuel tank for any signs of corrosion or damage, which could also be a source of the odor. If these steps do not reveal the problem, it may be time to consult a qualified mechanic for a thorough inspection. By methodically addressing these potential issues, you can effectively identify the source of the gas smell and take appropriate action.
If you're detecting a gas smell in your 2017 BMW 650i xDrive, it's crucial to understand the common problems that could be at play. One of the primary concerns is a fuel leak, which can stem from various components such as fuel injectors, fuel lines, or even the fuel tank itself. Additionally, a faulty or improperly secured fuel cap can allow fuel vapors to escape, contributing to the odor. Another potential issue lies within the evaporative emissions system, which is designed to manage fuel vapors; any malfunction here can lead to noticeable gas smells. Furthermore, leaks in the exhaust system, including the catalytic converter or exhaust pipes, may allow exhaust gases to infiltrate the cabin, creating a gas-like odor. Lastly, engine performance problems, particularly if the engine is running too rich and burning excess fuel, can also result in a gas smell. Addressing these issues promptly is essential for both safety and vehicle performance, so consider consulting a qualified mechanic for a thorough inspection and diagnosis.
Addressing a gas smell in your 2017 BMW 650i xDrive is not just a matter of inconvenience; it is a critical safety issue that requires immediate attention. Ignoring this symptom can lead to severe consequences, including the risk of fire or explosion due to gasoline leaks, which can ignite from hot engine components or electrical sparks. Additionally, the health risks associated with inhaling gasoline fumes are significant, as they can cause dizziness, headaches, and nausea, with prolonged exposure potentially leading to more serious health complications. Furthermore, a gas smell often indicates a leak in the fuel system, which can compromise your vehicle's fuel efficiency and lead to costly engine damage if not addressed. Therefore, if you detect a gas smell, it is essential to act quickly. While some DIY inspections can be performed, such as checking for visible leaks or loose connections, it is highly advisable to consult a qualified mechanic to ensure the issue is resolved safely and effectively.
