FAQs of Audi OBD2 Scanning

Where is the OBD port in an Audi?

In Audi vehicles, the OBD2 port is typically located in the following places:

1. Under the driver's side dashboard: in most 1996 and later models, the OBD2 port is located under the driver's side dashboard, near the left side of the steering column.
2. Near the brake pedal: for some models, such as the Audi A6, the OBD2 port is located under the driver's side dashboard, specifically above the brake pedal.
3. Near the center console: If the OBD2 port is not found under the dashboard, it may be located next to the center console, near the parking brake handle. It may be necessary to use a small flathead screwdriver to remove the plastic cover to expose the OBD2 port.
4. Audi A4 (B8) 2008-2015 models: the OBD2 connector is located near the pedal, specifically above the brake pedal.
5. Audi TT: The OBD2 port is located above the instrument panel, near the brake pedal.
6. Audi A6 1995-2014 models: in some Audi A6 models, the OBD2 port is located next to the emergency parking brake handle. Removing the small cover exposes the OBD2 port.

How do I find my Audi fault code?

To find trouble codes in your Audi vehicle, you can follow these steps:

1. Locate the OBD2 port: in most 1996 and later models, the OBD2 port is located under the dashboard on the driver's side, near the left side of the steering column.
2. Use an OBD2 scanner: Use a professional-grade OBD2 scanner compatible with your Audi. This scanner reads and clears trouble codes, provides real-time data, and accesses deeper levels of vehicle data.
3. Connecting the Scanner: Connect the OBD2 scanner to your vehicle's OBD2 port. Typically, this port is located under the dashboard and you may need to use a small flathead screwdriver to remove the plastic cover to expose the OBD2 port.
4. Turn the ignition on: Turn the vehicle's ignition switch to the ON position, but do not start the engine. If your Audi has a START/STOP function, press the button without pressing the brake pedal.
5. To read trouble codes: Follow the scanner's prompts, go to the “Diagnostics” or “Scan” menu, select “Audi” as the vehicle manufacturer, and select the correct model and chassis. Select “Audi” as the vehicle manufacturer and select the correct model and chassis type to synchronize the scanner with your vehicle.
6. Select Control Unit: Select the specific control unit you want to diagnose, such as the Engine Control Module (ECM), Transmission Control Module (TCM) or ABS Control Module. You can also select “Quick Scan” to check all systems.
7. Interpreting Codes: Once the scanner completes the code retrieval process, the codes displayed will provide information about the specific problem detected by the control unit. Write down these codes for further analysis and diagnosis. Each DTC consists of a letter and four numbers, with the letter indicating the affected system and the number more accurately describing the problem.
8. Clear Codes: after the problem has been repaired, return to the scanner menu and select the Clear Codes or Delete Codes option. This will remove the stored trouble code from the control unit's memory, indicating that the problem has been resolved.

By following these steps, you can easily locate and interpret trouble codes in your Audi vehicle so that you can repair and maintain it accordingly.
