Knowing where to find your Audi A4’s OBD2 connector is crucial for anyone who wants to delve into the world of vehicle diagnostics. Whether you’re a seasoned mechanic or a car enthusiast looking to troubleshoot a check engine light, this guide will provide you with everything you need to know.

The OBD2 port, short for On-Board Diagnostics, is the gateway to your Audi A4’s computer system. It allows you to connect a diagnostic tool, also known as an OBD2 scanner, to read and interpret diagnostic trouble codes (DTCs), monitor live sensor data, and perform various tests.

Locating the OBD2 Port in Your Audi A4

In most Audi A4 models, the OBD2 port is conveniently located beneath the dashboard on the driver’s side. To find it:

1. Sit in the driver’s seat and look below the steering wheel towards the pedals.
2. Inspect the area beneath the dashboard trim panel. You should see a trapezoidal-shaped connector with 16 pins.
3. This is your Audi A4’s OBD2 port.

Note: While the location described above is standard for most Audi A4 models, the exact position might vary slightly depending on the model year and trim level. If you’re having trouble finding it, consult your owner’s manual or refer to online resources specific to your car’s year and model.
