Where is the OBD Port on the Citroën C5?

Model: Citroen C5 C5 X, MK 3 - Years 2021-2026

The OBD port on the Citroen C5 is located inside the cabin; specifically, the port is installed under the left dashboard. Unlike other vehicles, the port is covered by a hard plastic protection to prevent dust and debris from blocking its operation. To connect to the port, it is necessary to remove the cover by pulling it outward, and only then will you have access to the blue port. Using the diagnostic port is essential when a computerised diagnosis is needed to identify problems from the control unit or sensors.
