2 Answers
The computer interface of the Peugeot 408 is located under the steering wheel, where the driver's left knee rests. Inside this area, you will find the computer interface. The computer interface, also known as the OBD interface, stands for On-Board Diagnostics, which translates to the onboard diagnostic system in Chinese. This system continuously monitors the engine's operating conditions and the working status of the exhaust after-treatment system. If any issues are detected, they are recorded and stored. The Peugeot 408 is a compact car launched by Dongfeng Peugeot, equipped with the mainstream engines from Shenlong Company, offering two displacement options: 2.0L and 1.6L. The dimensions of this car are 4750 mm in length, 1820 mm in width, and 1488 mm in height, with a wheelbase of 2730 mm.
I've been driving a Peugeot 408 for many years, and the computer interface is located on the left side under the driver's seat, specifically right below the steering wheel near the accelerator pedal. There's a small cover that you can lift to see it. It's an OBD port used to connect diagnostic tools, such as for checking fault codes, reading data during repairs, or periodic emissions testing. I remember one time when the engine light came on, and I spent a long time searching for this spot—only to find it was a minor issue. Most car models have it in this location; it's easy to overlook but very important. If you're the owner, just crouch down and look, and you'll find it. During routine maintenance, technicians often use it to service the car's systems, saving the trouble of dismantling parts. The fixed position is convenient, but don’t let dust accumulate—wipe it regularly to keep it clean and prevent poor contact. If you can’t use it yourself, it’s safest to seek help from a professional shop. In short, just remember it’s below the steering wheel near your feet.
