I recently purchased my 07 XK and feel a little limited on what I can do in terms of diagnosing items. I have a BlueDriver ODBII reader, which is good for the basic things. I am spoiled with my Saab I have a Tech 2 and can go in and make any changes I want to the car and diagnose things to a macro level with it. Is there a similar device for the Jaguar?

 

Get a copy of the old SDD application. You'll need to run it on an old laptop, with old software. There are so many threads on this.
