Where is the diagnostic port of the Peugeot 3008 located?

The OBD diagnostic interface of the Peugeot 3008 is located in the fuse box area below the left side of the steering wheel. Simply pull the cover panel outward to access it. The OBD interface is the black and green socket. OBD stands for On-Board-Diagnostic, which translates to "On-Board 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 condition that may cause excessive emissions is detected, it will immediately issue a warning. When a fault occurs in the system, the Malfunction Indicator Lamp (MIL) or Check Engine warning light will illuminate. At the same time, the OBD system stores the fault information in memory, which can be read in the form of fault codes through standard diagnostic tools and interfaces. Based on the fault codes, maintenance personnel can quickly and accurately determine the nature and location of the fault. The Peugeot 3008 has body dimensions of 4435mm in length, 1840mm in width, and 1652mm in height, with a wheelbase of 2613mm. It is equipped with a 1.6-liter turbocharged engine, delivering a maximum horsepower of 167ps. This engine provides greater output power and torque while further improving fuel economy and reducing exhaust emissions. The Peugeot 3008 comes with a 6-speed automatic transmission, a top speed of 205 km/h, a front MacPherson strut independent suspension, and a rear torsion beam non-independent suspension. The tire specifications are 225/50R17. System Structure: Scanner: The OBD-II regulation specifies fault codes, numerous engine management sensor signals, computer commands, etc., which can be read through a universal scanning tool. Oscilloscope: Oscilloscopes come in both desktop and handheld versions. Using an analog oscilloscope to check ignition system faults has been practiced for decades, but it is entirely different from modern laboratory oscilloscopes. Traditional analog oscilloscopes require the displayed signal to be a repeating periodic signal, whereas laboratory oscilloscopes display the signal in real-time. Due to the high sampling frequency, every important detail of the signal is displayed, allowing any signal that could cause a fault to be identified while the engine is running. Interface: The OBD-II program is designed to avoid confusion between systems, requiring the use of a standard 16-pin diagnostic interface, specific coding, and component descriptions in the manufacturer's documentation to achieve uniformity and standardization. Every vehicle is equipped with a standard-shaped and sized 16-pin diagnostic interface, with each pin's signal allocation identical and located in the same position, installed below the dashboard, somewhere between the left side of the dashboard and 300mm to the right of the vehicle's centerline. The OBD device monitors multiple systems and components, including the engine, catalytic converter, particulate filter, oxygen sensor, emission control system, fuel system, EGR, etc. OBD connects various emission-related component information to the Electronic Control Unit (ECU), which has the capability to detect and analyze emission-related faults. When an emission fault occurs, the ECU records the fault information and related codes, and issues a warning through the malfunction indicator lamp to inform the driver. The ECU ensures access to and processing of fault information through a standard data interface.
I remember driving a Peugeot 3008 for several years, and the OBD port is located below the steering wheel on the driver's side. Just look down around the knee area. Specifically, it's at the left corner of the dashboard where your left foot rests, usually covered by a small panel. Once removed, you'll find the standard 16-pin connector. I often use it to connect a diagnostic tool for checking fault codes—its position is quite thoughtful, easy to reach without getting in the way. If a warning light appears on the dashboard during daily driving, you can connect your device here to troubleshoot, saving a trip to the repair shop. Just be careful not to tug the wires when plugging or unplugging, and wipe off dust if it accumulates. Most cars place it in a similar spot, and Peugeot is no exception.
Based on my experience tinkering with cars, the diagnostic port for the Peugeot 3008 is located under the dashboard on the driver's side, near the left side of the steering wheel. You'll need to crouch down and look above the knee area, where it's usually covered by a plastic cap. This placement has remained consistent from older to newer models, designed for easy maintenance access. Connecting an OBD device allows reading real-time data, which is particularly useful for troubleshooting engine issues. Avoid unnecessary unplugging to prevent port loosening, and always ensure the engine is off during checks for safety. Knowing its location enables DIY minor repairs, saving both money and time efficiently.
