The indie is not totally correct. You can buy a clone or original jlr mongoose and use a copy of the Jaguar SDD/IDS program to reflash but I would use it to get the codes first to diagnose the problem fully. I use the device to read deeper than many other Obd readers that are available.

 

We have a lot of people just install the throttle body so while it would be a good idea to follow that document but it seems to not be needed.

Went through the sticky procedure this weekend of re-calibrating the throttle body and no luck. Must be something else.
Haven't had a chance to take the car back to the indy but that will be the next step this week.
