Where is the OBD connector located in Citroën vehicles?

The OBD interface in Citroën vehicles is generally located inside a small compartment in front of the gear lever or under a small cover near the left knee position. Here is a detailed introduction to the OBD system: 1. Principle: OBD continuously monitors systems and components such as the engine, catalytic converter, particulate filter, oxygen sensors, emission control system, fuel system, EGR, etc. It then connects to the ECU (Electronic Control Unit) with information from various emission-related components. The ECU can detect and analyze faults related to emissions. When an emission fault occurs, the ECU records the fault information and relevant codes, alerts the driver by illuminating the malfunction indicator light (MIL), and ensures access to and processing of fault information through a standardized data interface. 2. Function: After the implementation of the OBD-II program, any technician can use the same diagnostic tool to diagnose any vehicle manufactured according to the standard. One of the mature features of OBD-II is that when the system triggers the malfunction indicator light, it records data from all sensors and actuators, which greatly facilitates diagnostic and repair needs.
I've always been a commuter who drives to work, and I often help friends locate the OBD port, especially in Citroën cars. It's usually hidden behind a small cover under the driver's seat, on the left side of the dashboard, or above the footwell. Last time I drove a Citroën, I lifted that plastic panel, and the port was right there—the design is quite convenient, as you don’t have to bend over too much. If you can’t find it, I’d suggest checking the vehicle manual first, as it has detailed diagrams, or asking a professional, since different models might place it on the passenger side. The OBD system is quite smart these days—it can help detect minor issues, so don’t miss out on its diagnostic functions. Just keep the port clean regularly.
