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 faced with a gas smell in your 2017 BMW 650i Gran Coupe, it's crucial to adopt a systematic diagnostic approach to identify the underlying issue. Start with a thorough visual inspection of the vehicle, looking for any obvious signs of fuel leaks both inside and outside, particularly around the fuel lines and engine compartment. Next, check the fuel injectors for any signs of malfunction or leakage, as these components can often be the source of fuel odors. After that, ensure that the gas cap is securely sealed; a loose or damaged cap can allow gas vapors to escape, creating a noticeable smell. If these initial checks do not reveal the problem, consider inspecting the evaporative emissions system for any leaks or malfunctions, as issues here can also lead to gas odors. Finally, examine the exhaust system for any leaks, as these can sometimes produce a gas smell inside the vehicle. By following this structured approach, you can effectively narrow down the potential causes of the gas smell and take the necessary steps to resolve the issue.
If you're detecting a gas smell in your 2017 BMW 650i Gran Coupe, it's crucial to understand the common problems that could be at play. One of the primary culprits is a fuel leak, which can occur from various components such as damaged fuel lines, a compromised fuel tank, or malfunctioning fuel injectors. Additionally, a faulty fuel injector may not properly atomize fuel, leading to an unpleasant odor inside the cabin. Another potential issue could stem from the evaporative emissions system, which is designed to capture and recycle fuel vapors; any malfunction here can result in noticeable gas smells. Furthermore, an exhaust system leak, particularly near the engine, can sometimes mimic the scent of gasoline, creating confusion. Lastly, if you've recently overfilled your gas tank, spilled fuel can easily lead to lingering odors. For those inclined to DIY, it's advisable to conduct a thorough visual inspection of the fuel system and emissions components, but remember that persistent issues should be evaluated by a professional mechanic to ensure safety and proper vehicle operation.
If you detect a gas smell in your 2017 BMW 650i Gran Coupe, it is essential to act swiftly due to the potential safety risks involved. Ignoring this symptom can lead to severe consequences, including fire hazards or significant damage to your vehicle. Start by immediately ceasing to drive the car to prevent any dangerous situations. Conduct a thorough inspection for any visible signs of fuel leaks, particularly around the fuel tank and lines, as these are common culprits. It is crucial to avoid starting the engine, as this could ignite any leaked fuel. If you identify any leaks or if the smell persists, it is advisable to consult a qualified mechanic or your BMW dealership for a professional assessment and repair. Additionally, adhering to regular maintenance schedules can help prevent such issues from arising in the future, ensuring your vehicle remains safe and reliable. By taking these precautions, you not only protect yourself but also maintain the integrity of your BMW.
