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 2016 BMW 650i, it's essential to adopt a systematic diagnostic approach to identify the root cause effectively. Start by inspecting the area beneath your vehicle for any visible fuel leaks, as these are often the most straightforward issues to detect. Next, examine the ventilation system, focusing on components like venting tubes and the purge valve, which can sometimes develop leaks that allow fuel vapors to escape. If these checks do not reveal the source of the smell, turn your attention to the heating system, as it can also contribute to unpleasant odors if there are any leaks or malfunctions. If you still cannot pinpoint the issue, it may be time to consult a qualified mechanic who can perform a more thorough inspection. By following this structured approach, you can efficiently diagnose and address the gas smell, ensuring your vehicle remains safe and comfortable to drive.
When you notice a gas smell in your 2016 BMW 650i, it's crucial to identify the underlying issues that could be causing this problem. Start by examining the gas cap, as a loose or damaged cap can allow fuel vapors to escape, leading to noticeable odors. Next, consider the integrity of the fuel system; over time, seals and o-rings can deteriorate, resulting in leaks that allow gasoline vapors to enter the cabin. Additionally, inspect the fuel injectors, as any malfunction or leakage can contribute to fuel escaping and creating unpleasant smells. It's also important to check for leaks under the hood, which may be due to a faulty fuel pressure regulator or issues with the charcoal filter. By addressing these potential problems, you can effectively eliminate the gas smell and ensure your BMW remains safe and reliable. If you're unsure about performing these checks yourself, seeking assistance from a qualified mechanic is advisable for a comprehensive diagnosis.
Addressing a gas smell in your 2016 BMW 650i is not just a matter of convenience; it is a critical safety concern that requires immediate attention. The presence of gasoline odors can signal serious issues within the fuel system, such as leaks or malfunctioning components, which could lead to hazardous situations if left unchecked. Additionally, unburned fuel escaping through the exhaust may indicate deeper mechanical problems that could compromise your vehicle's performance and safety. A seemingly minor issue, like a loose or faulty gas cap, can escalate into significant fuel vapor leaks, potentially triggering warning lights and further complications. More alarmingly, neglecting a gas smell could point to severe problems, such as fuel pump failures, which can result in engine stalling and pose serious safety risks while driving. Therefore, if you detect a gas smell, it is imperative to investigate the source immediately to safeguard your well-being and prevent costly repairs down the line. Taking prompt action not only protects you but also ensures the longevity and reliability of your BMW.
