I am still sorting out a new to me 2006 XJR. I am not quite a newbie, have a 2005 Audi A8 and so much is alike between the two vehicles.
I have a VAG-COM for it. Reading and searching, the equivalent product for the Jaguar is not clear. Is there a one stop shop with software and cable for reading and clearing codes?

 

If I were in the market now I'd buy the iCarsoft i930, will read all modules and sensors on Jags & Land Rover.

The dealer level equipment IDS/SDD is nice to have but the i930 is far more practical & user friendly, and also reads other makes to (albeit only generic OBD, not the manufacturer specific, that's only for JLR vehicles)

 

The IDS/DSS looked to be a challenge. Glad there is something more user friendly.
