The OBD port of the Dongfeng Citroen C-Quatre is located inside the ashtray in front of the gear lever. You need to remove the ashtray when using it. The function of the OBD port: OBD is the abbreviation of OnBoard Diagnostics, commonly known as the on-board self-diagnosis system. Its function is to monitor the working status of the engine and other working modules in real-time during the operation of the car. Once an abnormality is found, it will be recorded in the memory in the form of a fault code. When performing maintenance and inspection on the car, maintenance personnel can quickly and accurately locate the relevant parts through the fault code for subsequent repairs. The OBD system monitors whether the car's exhaust exceeds the standard at any time from the engine's operating conditions. Once it exceeds the standard, it will immediately issue a warning. When the system fails, the fault (MIL) light or the Check Engine warning light will come on, and the Powertrain Control Module (PCM) will store the fault information in the memory. The fault code can be read from the PCM through a certain program. According to the prompt of the fault code, maintenance personnel can quickly and accurately determine the nature and location of the fault. The style of the car OBD port: The OBD port is generally a 16-pin female interface, and the interface is trapezoidal. Some models have a protective cover on the OBD port. Common OBD ports are black, white, or blue.
I've been driving this car for years and am quite familiar with locating the OBD port. It's usually positioned just below the steering wheel, slightly above where your left foot rests on the pedal. Crouch down and you'll spot a small black connector tucked along the edge of the dashboard. Sometimes dust may cover it - just wipe it clean before use. While not particularly hard to find, first-time Citroen C4 drivers should use a flashlight and search carefully without rushing. Remember to turn off the engine before connecting the scanner to avoid accidents. Last time I used it to check trouble codes, it helped fix an engine issue - really handy. For regular maintenance, keeping the port clean prevents poor contact during diagnostics.
