The computer port of the Peugeot 408 is located under the cover beneath the buttons on the left front side of the driver's seat. Open the cover to find the green connector, which is the OBD port, also known as the computer port. Detailed information is as follows: 1. There are Jack and USB ports under the cover inside the front center armrest box. 2. The OBD port is generally a 16-pin female connector, trapezoidal in shape, making it easy to identify. 3. Some models have a protective cover over the OBD port, and the visible OBD port is usually black, white, or blue. 4. OBD stands for On-Board Diagnostics, an onboard automatic diagnostic system, displayed on the dashboard as a symbol resembling a faucet.
During my years of using the Peugeot 408, the computer port is usually located near the driver's seat. At knee height below the steering wheel on the left side, you can see a small slot by looking down, which is mainly used to connect diagnostic equipment for scanning vehicle fault codes or updating the system. My car is the 2019 model, and the port is behind a plastic cover in the lower left corner of the dashboard—quite hidden, but you can access it by removing the cover. Don’t worry about it being hard to find; it was designed for convenience, and technicians use it frequently during routine maintenance. I recommend checking it regularly to prevent dust buildup from affecting the connection. If you’re handling it yourself, insert and remove the connector gently to avoid damage. The position may vary slightly in different model years of the 408, but it’s generally the same. If you can’t find it, check the vehicle manual or consult a professional repair shop.
The OBD port location on the Peugeot 408 is very intuitive, hidden just below the steering wheel on the left side. When seated, drivers will find a square-shaped connector in front of their knees, designed for OBD scanners or software devices. I've successfully used a Bluetooth OBD adapter here to connect with mobile apps for real-time data like fuel consumption or engine codes – incredibly useful. Positioned at the central wiring point of the vehicle, it allows easy plugging but avoid forceful insertion to prevent pin damage. Keep the area clear of clutter, and during maintenance, check for minor positional adjustments. Even beginners can locate it effortlessly; if unsure, online owner forums provide visual guides. Always ensure the engine is off for safe, risk-free operation.
