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 2023 Audi A4 allroad, it's essential to adopt a systematic diagnostic approach to identify the underlying issue effectively. Start by inspecting the fuel system for any visible leaks, focusing on components like fuel lines, injectors, and the fuel tank. A common culprit can be a faulty or loose fuel cap, so ensure it is securely tightened to prevent gas vapors from escaping. Next, examine the exhaust system for any signs of leaks or damage, as these can also contribute to the odor. Utilizing a diagnostic scanner can help you check for error codes related to the fuel system or emissions components, providing further insight into potential issues. If no obvious problems are found, consider performing a pressure test on the fuel system to detect hidden leaks. Additionally, inspect the evaporative emissions system, including the charcoal canister and purge valve, as malfunctions here can lead to gas smells. Finally, monitor your engine's performance for any signs of misfires or unusual sounds, which may indicate incomplete combustion and contribute to the gas odor. By following this structured approach, you can effectively diagnose and address the source of the gas smell in your vehicle.
