Modern vehicles, including the Audi A3, rely heavily on sophisticated software and numerous Electronic Control Units (ECUs) to manage various systems. Diagnosing issues in these complex systems requires specialized tools that can interface with the car’s computer. This is where the On-Board Diagnostics II (OBD2) port comes into play. Since 2004, and in some cases even earlier, OBD2 ports have been a standard feature in vehicles, providing a standardized access point for diagnostic scanners.
This OBD2 port is invaluable, allowing you to connect a scanner to your Audi A3 to read diagnostic trouble codes, access performance data, and even unlock hidden features. However, the exact location of the OBD2 port can vary depending on the car model and manufacturer. For Audi A3 owners, finding this port is the first step towards taking control of your car’s health and performance. Typically, the OBD2 port in an Audi A3 is positioned in a location that is accessible from the driver’s seat.
For Audi A3 owners looking for a user-friendly diagnostic solution, the Carly App and OBD2 adapter offer a powerful combination. This tool enables you to perform in-depth diagnostics of your Audi A3 without needing a visit to a professional workshop.
Beyond basic diagnostics, Carly provides a wide range of functionalities for Audi vehicles. The specific features available can differ based on the ECUs and software installed in your particular Audi A3 model.

Locating the OBD2 Port in Your Audi A3
While the video in the original article visually guides you, understanding common locations can be helpful. In the Audi A3, the OBD2 port is most commonly found in one of these locations:
- Under the Dashboard (Driver’s Side): This is the most frequent location. Look beneath the steering wheel column and around the knee area. The port is often integrated into the lower dashboard trim. You might need to crouch down to get a clear view.
- Within the Glove Box: In some Audi A3 models, the OBD2 port might be located inside the glove compartment. Check the upper or side walls of the glove box for a covered port.
- Center Console Area: Less commonly, but possibly in certain A3 trims, the port could be near the center console, perhaps below the infotainment system or gear selector.
Remember to consult your Audi A3 owner’s manual for the most precise location information specific to your model year and trim. However, checking the areas mentioned above will usually lead you to the OBD2 port quickly. With the port located, you are ready to connect your Carly OBD2 reader and start exploring the diagnostic and customization possibilities for your Audi A3.
