Where is the OBD connector generally located in Citroën vehicles?

The OBD connector in Citroën vehicles is generally located inside the ashtray in front of the gear lever, and the ashtray needs to be removed when in use. Citroën's models include the Citroën C6, Citroën C5, Citroën C3-XR, C4 C-Quatre, and the new Elysée. Taking the Citroën C4 C-Quatre as an example: its length, width, and height are 4588mm, 1773mm, and 1486mm respectively, with a wheelbase of 2610mm, equipped with a 5-speed manual transmission. The engine of the Citroën C4 C-Quatre has a maximum power of 86 kilowatts and a maximum torque of 150 Newton-meters, with a MacPherson independent front suspension and a variable crossbeam with a stabilizer bar rear suspension.
I've worked on many Citroën models before and found the OBD interface is usually hidden behind the trim panel below the steering wheel on the left side. You need to crouch down and look under the dashboard, right above the accelerator pedal area – just reach in and you'll feel the 16-pin black connector. For some older models like the Xsara, it might be installed on the side of the center console near the gearshift, but newer models like the C4 and C5 Aircross mostly have it below the steering wheel. Remember not to force the diagnostic device when plugging it in – make sure the connector orientation is correct before pushing it in, especially in winter when plastic clips become brittle and the mounting tabs can easily snap. If you still can't find it, check under the driver's seat mat or inside the glove compartment – some French cars love to hide it in these tricky spots.
I drive a used Citroën C3, and it took me half an hour to locate the OBD port for the first time. Later, I found it right next to the fuse box, behind the cover panel on the left side of the steering column. Just reach down around knee level, and you'll feel the trapezoidal port with a dust cover. Note that some right-hand-drive cars may have it on the passenger side, but for left-hand-drive cars in China, it's mostly on the driver's side. If the seat position has been adjusted, it might be covered by floor mats—my friend couldn't find his for ages because of this. Also, a quick reminder: use a dedicated OBD cable, not a phone charging cable, as unstable voltage could fry the ECU.
