I’m over on the Jag forum too… have an ‘05 S Type R

This is a long shot, but proved true in my case. STR started getting CEL with several random codes, cam sensors, HVAC issues, evap system leak.

Started trying to rule things out like you are. A logical approach.

Got very frustrated as things kept popping back up.

In the end it was a battery that was old and getting weak. It apparently couldn’t process all the data at the various control modules.

New battery and all good. 👍
