Where is the OBD port located on the 408?
2 Answers
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.
