OBD2 Port Location
Looking for the plug-in point for your OBD2 code reader in the Citroën C4?
First Generation (2004-2009)
You can find the OBD2 port location for the first generation C4 hidden underneath the ashtry in the center of the dashboard.
All you have to do is peel away the plastic trim underneath the ashtray to expose the port.
Second Generation (2010-2019)
Again, the OBD2 location is in the center of the dashboard underneath the controls for the heating etc.
Underneath the controls (as illustrated in the photo to the left) the plastic has a gap where you can pry it away.
If you put your fingers where the yellow arrow is showing then you should be able to pull the plastic away and expose an OBD2 port.
Third Generation (2020+)
For the later models of the Citroën C4, you will find the diagnostic port tucked away underneath the steering wheel in a much easier place to get too.
It may be hidden behind an easily removable panel directly under the steering wheel or exposed, ready to be plugged into.

About the C4
A small family car built by the French automaker Citroen, the C4 can be classed as a compact crossover SUV.
Chosen to replace the Citroen Xsara, the launch took place in 2004 at the Geneva Motor Show. Designed by the creative team that housed Donato Coco and Jean Ploue, the C4 was available in two body types, a five-door hatchback and a three-door coupe. C
Citroen championed the fact that the C4 benefitted from some modern technologies with things like lane departure warning, directional headlights, translucent dashboards and the less common feature, a perfume dispensary installed in the air vent system.
By 2010, Citroen had brought out the second generation of C4s; these models were less eccentric looking with a less bubbled chassis and horizontal accents sweeping across the door panels.
Buyers could choose from a number of engines ranging from the 1.4-liter petrol up to the 2-liter diesel; these could be selected with a five-speed manual transmission or a 6-speed automatic.
For people wishing to consider alternatives to the Citroen C4, they could choose from the Ford Focus, Skoda Octavia, Volkswagen Golf, Vauxhall Astra, Kia Xceed, Mazda CX-30, Toyota C-HR or the Renault Arkana.
