Where is the diagnostic plug on an x type jag?

On a Jaguar X-Type, the diagnostic plug, also known as the OBD-II port, is typically located under the dashboard, near the driver's side. You can find it by looking beneath the steering column, close to the area where the steering wheel meets the dashboard. It may be concealed by a cover, so check carefully. This port is used for connecting diagnostic tools to read error codes and perform vehicle diagnostics.
