The OBD interface of Peugeot 408 is located under the steering wheel, inside the cover panel near the left knee. Here is some relevant information: 1. OBD full name: On-Board-Diagnostics, translated into Chinese as: On-board self-diagnosis system. "OBD-Ⅱ" is the abbreviation of "on-Board-Diagnostics-Ⅱ", which means Type II on-board diagnostic system. In order to standardize the diagnosis of vehicle emissions and drivability-related faults, starting from 1996, all new cars sold in the United States must have similar diagnostic instruments, fault codes, and repair procedures, that is, comply with the OBD-Ⅱ program regulations. With the increasing globalization of the economy and the internationalization of automobiles, as the basis for drivability and emission diagnosis, the OBD-Ⅱ system will be implemented and applied more and more widely. 2. As a system for monitoring exhaust emissions, OBD has gradually expanded its control scope in later development. With the improvement of various sensors and the degree of electronicization of vehicles, OBD has incorporated various monitoring functions into its jurisdiction. Nowadays, when talking about OBD, the term OBD interface is generally used, because only the transmission interface of this system can be seen on the vehicle, but behind it is actually the entire vehicle control system.
On my Peugeot 408, the OBD port is located slightly to the left under the steering wheel, right above the brake pedal. As someone who frequently drives long distances, I always plug my OBD diagnostic device there—it's thoughtfully designed so you can easily reach it by just bending over, without it getting in the way of your feet or affecting driving. The area is usually inconspicuous, just covered by a small flap. A helpful tip is to keep that area clean and free of dust, as buildup can cause poor contact. For safety, it's best to park and turn off the engine before performing diagnostics. Remember not to poke around other ports randomly to avoid damaging the circuits, as car repairs can be costly and troublesome.
