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.
When the fuel filter begins to clog, the engine suffers from fuel starvation. This will cause a significant reduction in power and may also cause a misfire.

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 diagnosing a gas smell in your 2016 Audi RS7, it's essential to adopt a systematic approach that prioritizes safety and efficiency. Start by checking for visible leaks under the vehicle, as this can quickly indicate if there's a significant issue with the fuel system. Next, inspect the fuel lines and connections for any signs of wear or damage, as these components are often the culprits behind fuel odors. Don't overlook the fuel tank itself; any signs of leaks or corrosion here can lead to serious problems. Additionally, examine the fuel injectors and fuel filter, as a malfunctioning injector or a clogged filter can contribute to the smell. It's also crucial to assess the evaporative emissions control system, which plays a vital role in managing fuel vapors. Lastly, inspect the exhaust system for leaks that might allow fumes to enter the cabin. If these steps do not reveal the source of the gas smell, consulting a professional mechanic is advisable to ensure a thorough diagnosis and safe resolution of the issue. By following this diagnostic approach, you can effectively identify and address the cause of the gas smell in your Audi RS7.

One of the most common culprits is a fuel leak, which can occur anywhere in the fuel system, from the tank to the injectors. Inspecting the fuel lines and connections for any signs of leakage is a good starting point. Another potential issue could be a faulty fuel injector, which may not seal properly, allowing fuel to escape and create a noticeable odor. Additionally, problems with the evaporative emissions system can lead to gas vapors entering the cabin; checking the system for any blockages or malfunctions is advisable. An exhaust system leak can also contribute to gas smells, as exhaust gases may infiltrate the vehicle’s interior. Lastly, a clogged air filter can disrupt the air-fuel mixture, potentially resulting in a gas odor. Addressing these issues promptly is essential, and while some DIY fixes may be possible, consulting a qualified mechanic for a thorough inspection is recommended to ensure a safe and effective resolution.
Addressing a gas smell in your 2016 Audi RS7 is not just a matter of inconvenience; it is a pressing safety concern that requires immediate attention.
