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 2007 BMW 335xi, it's essential to approach the diagnosis methodically, starting with the most straightforward checks before moving on to more complex issues. Begin by inspecting the fuel system for any visible signs of a gasoline leak, as this is a critical safety concern that should be addressed immediately. Look closely at the fuel tank, lines, and injectors for any signs of leakage. If no leaks are found, the next step is to examine the fuel pump and regulator, as problems with these components can also lead to a gas smell. Ensure that the High-Pressure Fuel Pump (HPFP) is properly installed and that all connections are tight, especially if it has been recently replaced. Additionally, check the sealing washers on the spark plugs, as damaged or improperly torqued washers can allow fumes to escape into the intake system. By following this structured diagnostic approach, you can effectively identify the source of the gas smell and take the necessary steps to resolve the issue, ensuring both your safety and the proper functioning of your vehicle.
When you detect a gas smell in your 2007 BMW 335xi, it’s crucial to understand the common problems that could be at play. One of the first areas to check is the gas cap; if it’s loose or damaged, it can allow fuel vapors to escape, leading to a noticeable odor. Additionally, inspect the fuel system components, including the fuel pump, fuel filter, and fuel injectors, as leaks in these areas are frequent culprits. The emissions control system also warrants attention, as any malfunction can contribute to gas smells. Furthermore, be aware that faulty wiring in the fuel pump, particularly in models from 2007 to 2012, may indicate a more serious issue that could require immediate action, especially if it relates to a recall. Given the serious risk of fire associated with gas leaks, it’s advisable to conduct a thorough inspection of the fuel system, including the fuel tank and spark plugs, to ensure your vehicle remains safe and functional. Addressing these issues promptly not only enhances your vehicle's performance but also safeguards your well-being on the road.
