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.

When faced with a gas smell in your 2021 Volvo XC40, it's essential to approach the diagnosis methodically, starting with the simplest solutions before moving on to more complex issues. Begin by inspecting the gas cap; a loose or damaged cap can easily allow fuel vapors to escape, creating an odor inside the vehicle. If the cap is secure, check for any visible signs of a fuel leak beneath the car or around the fuel tank, as this could indicate a more serious problem like a leaking fuel line or faulty injector. Next, consider the evaporative emissions system, which is designed to contain fuel vapors; any malfunction here can lead to noticeable gas smells. Additionally, inspect the exhaust system for leaks or damage, as these issues can also allow gas odors to infiltrate the cabin. If these steps do not reveal the source of the smell, it may be time to consult a professional mechanic who can conduct a thorough inspection with specialized tools. By following this diagnostic approach, you can effectively identify and address the cause of the gas smell, ensuring a safer and more comfortable driving experience.

A common culprit is a fuel leak, which can arise from damaged fuel lines, faulty fuel injectors, or problems with the fuel tank itself. Additionally, the evaporative emissions system, responsible for controlling fuel vapor release, may be malfunctioning, leading to the odor. Another potential source is the exhaust system; leaks or issues with components like the catalytic converter can allow gas-like fumes to infiltrate the cabin. It's also worth noting that overfilling the gas tank is a frequent mistake that can result in fuel spillage and unpleasant smells.
