E-Diff Fault
#1

I've got a '13 XFR with about 24K miles. My warranty expires in February of 2018 (10 months to go).
Yesterday, after driving the car to work in the morning, I had to run a quick errand. Upon startup, I got the E-Diff Fault error message on the screen. Stopping/starting the car again did not clear it. After driving around to run my errand, I parked it for 7 or 8 hours.
When I started it back up in the afternoon, the fault was gone. I never noticed any weird driveability issues.
How concerned should I be that my e-diff is toasted? The car is at the dealer now... is there anything i should tell them to be sure to inspect? It's a dealership that recently added Jaguar to their stable of brands, so they are not experienced with Jaguar per se.
Any advice appreciated.

A low battery voltage can cause all sorts of errors, including with the E-Diff. Do you use the car regularly? It might be a sign of the battery starting to fail. If it's still the factory one (likely with a 2013 car) then this is a possibility, especially with "phantom" errors.
The E-Diff is operated by an electric motor, so if anything has toasted with these symptoms showing (and it's very unlikely if you couldn't see a problem that anything is toast) it's most likely to be the motor or a sensor associated with it, which would hopefully limit any repair cost.
Worth getting the dealer to check for any codes, but beyond that, I wouldn't be too concerned.
