Where is the OBD socket located on the Citroen C4?

Model: Citroen C4 MK 2 - Years 2010-2018

Today we will explain how to access and use the OBD port of the Citroen C4. The OBD port is located inside the cabin, specifically under the central dashboard. To access the port, it is necessary to remove the lower part of the dashboard using a flathead screwdriver. After removing the cover, we can connect the port to a power cable leading to a diagnostic computer to perform a scan of the vehicle and address issues related to the control unit. Through the use of this port, it is also possible to perform reset operations.
