The OBD port of the Peugeot 408 is located below the steering wheel. It is positioned where the driver's left knee rests, and the computer interface is inside. You need to pry open the cover under the steering wheel slightly and then pull it down slowly to open it. Once opened, you can see a green component, which is the OBD port. The Peugeot 408 is equipped with the following two engines: 1. A 1.2T inline 3-cylinder turbocharged engine, paired with either a 5-speed manual or 6-speed automatic transmission, delivering a maximum power of 100KW and a maximum torque of 230N·m. 2. A 1.6T inline 4-cylinder turbocharged engine, paired with a 6-speed automatic transmission, delivering a maximum power of 125KW and a maximum torque of 250N·m.

As a car repair enthusiast who often tinkers with vehicles myself, I can tell you that the Peugeot 408's computer port, also known as the OBD interface, is typically located slightly to the left under the steering wheel. You'll need to crouch beside the driver's seat and look downward—there's a plastic panel covering it. Gently pry it open to reveal a standard 16-pin connector. This port is used to connect diagnostic tools, such as for reading fault codes or adjusting vehicle data. If you can't find it, check under the floor mat or near the fuse box—it might be stuck. I recommend not forcing the connector; just align it properly to avoid damage. The standardized position makes it convenient for DIY installations, but always ensure the engine is off for safety. For routine maintenance, keep the interface clean to prevent oxidation and poor contact.

When I first bought the 408, I knew nothing about cars. Later, I learned that the OBD port is located in the knee area just below the steering wheel on the left side. When sitting in the driver's seat, you can see a small panel by lowering your head slightly. Lift it up, and the port is revealed - quite noticeable. The position is standardized, as all cars are designed this way. It's not difficult to connect a diagnostic tool to read data, so beginners don't need to worry about finding it. I also use it to connect my dashcam, which is quite convenient. Just a reminder: never fiddle with it while driving; it's safer to operate when parked. This interface is required by regulations and is mandatory for every vehicle, with its position typically remaining consistent across models.

As a car electronics enthusiast, I'm very familiar with the 408. Its OBD computer port comes standard under the dashboard on the driver's side. Look near the steering column for a small covered compartment - lift the protective cap to reveal the 16-pin interface. This connects directly to the ECU to access engine data, diagnose faults, or monitor fuel consumption effortlessly. The universal port design works with most scan tools, just ensure proper plug orientation during connection. Conveniently positioned yet unobtrusive for daily driving.
