hi - is there a diagnostic or test mode for our cars that is internal to the info display...i read about the S series having a diagnositc mode where you hold the trip reset button down and then start the car to see all sorts of other info...do the x308? have this...i have a 2001 XJR and like to see all sorts of info on the car...i am looking for some real time info...

 

not heard of this feature on the 308's - I suspect a high end OBD scan tool like autologic, Snap-on system with Jaguar key etc. Other than this type of thing, the IDS tool, Jaguar's factory software.
