Where is the OBD interface located on the Peugeot 408?

The OBD interface of the Peugeot 408 is located inside the instrument panel cover beneath the buttons on the left front side of the driver's seat. Open the cover, and you will find the OBD interface inside. The OBD interface can not only connect to a fault diagnosis computer but also to some external displays. Once connected, the external display can read certain data. Here is some relevant information: 1. The Chinese meaning of OBD is On-Board Diagnostics. During vehicle operation, this system can monitor the working conditions of the engine's electronic control system and other functional modules of the vehicle in real time. It uses specific algorithms to determine specific faults. If any abnormal conditions are detected, they are stored in the system's memory in the form of diagnostic trouble codes. 2. The system can assist in vehicle maintenance and repair by providing useful information obtained through self-diagnosis. Maintenance personnel can read the fault codes using the vehicle's original specialized equipment, enabling quick fault identification and facilitating vehicle repairs, thereby reducing manual diagnosis time.
As a long-time owner of the Peugeot 408, I've been driving this car for several years, and the OBD interface is located under the dashboard on the driver's side. The exact position is below the steering wheel, just a bit above where your knees would be. When you're seated in the driver's seat, look down, and you'll find it right above the left foot pedal—it's within easy reach. It's a 16-pin port, usually black or with a plastic finish, and remember to use a standard OBD scanner when plugging or unplugging. I often use the OBD to diagnose trouble codes, like checking issues when the warning light comes on, which is quite convenient. The placement is fairly user-friendly, similar to most cars, so you don't have to bend over too much. When inspecting, turn on the interior light or use a flashlight to avoid struggling to see. Also, keep the area around the interface dry and clean to prevent dust buildup from affecting the connection. If you've adjusted the seat position, it might block the port, so make sure to readjust properly.
I work in auto repair, and the Peugeot 408's OBD interface is standardly designed below the left side of the dashboard, in the area just ahead of the driver's knee. A common issue during operation is users not finding it, but it's actually located slightly below the steering column. Simply open the door and sit in the driver's seat to spot the port socket. For daily diagnostics, I use it to read data streams and troubleshoot engine or emission issues. The interface is made of plastic, so avoid applying excessive force to prevent damaging the socket pins. This placement follows international conventions, facilitating quick scanner tool connections and saving search time. Some car models hide it in storage compartments, but the Peugeot 408 doesn't—it's right there. Remember to regularly clean around the interface to prevent dust buildup from causing poor contact. If something accidentally gets stuck inside, don't yank it out; just take it to a professional shop for handling.
I've only been driving for a little over a year, and I got familiar with the OBD interface while driving my brother's Peugeot 408. It's hidden at the bottom of the dashboard, right in front of the driver's seat. When you sit down and look down, it's right above the left footrest area, easy to locate. It took me some time to find it the first time, but once I got used to it, I found the position reasonable—just plug in your phone app when parked to check RPM or fuel consumption data. It's a small socket with a simple and handy design. Always remember to plug and unplug gently to avoid scratching the interface. Its prominent location makes it easy for beginners to get started quickly. For safety, turn off the engine before connecting to avoid any mishaps.
