When dealing with a gas smell in your 2021 Audi SQ5 Sportback, it's essential to approach the diagnosis methodically, starting with the simplest solutions before moving on to more complex issues. Begin by inspecting the fuel system for any visible leaks, focusing on components like fuel lines, injectors, and the fuel tank. A common culprit for gas odors is a faulty or loose fuel cap, so ensure it is securely tightened and in good condition. Next, examine the exhaust system for any signs of leaks or damage, as these can also contribute to a gas smell. Utilizing a diagnostic scanner can help identify any error codes related to the fuel system or emissions components, providing further insight into the issue. If you suspect a more elusive problem, such as a leak not visible to the naked eye, performing a pressure test on the fuel system can be beneficial. Should these steps not reveal the source of the gas smell, consulting a qualified mechanic or dealership for a thorough inspection is advisable to ensure your vehicle is safe and functioning correctly. By following this structured diagnostic approach, you can effectively identify and address the cause of the gas smell in your Audi SQ5 Sportback.

Another potential issue is a faulty fuel injector; if you notice a strong odor, it may be worth checking the injectors for proper function, as a malfunction can lead to improper fuel delivery.
