Where is the OBD port located in UK cars?

In most UK cars, the OBD (On-Board Diagnostics) port is typically found beneath the dashboard near the steering column, close to the driver's knee area. Popular models like the Vauxhall Corsa, Ford Focus, and Nissan Qashqai all follow this standard placement. The OBD system monitors your vehicle's emissions and engine performance, alerting you via the dashboard warning light if issues are detected. Modern UK-spec vehicles use a standardised 16-pin trapezoidal connector (usually black, white or blue), with some models featuring a protective cover. Mechanics use this port to read fault codes and diagnose problems during MOT tests or servicing.
