The XF does not like having the battery disconnected. When these problems occur Jaguars solution is to replace both the Front and Central Junction Boxes and reprogram - cost over £1k. Find a garage with Autologic software and they will reprogram without changing the JBs normally for under £100.

If you change the battery always connect a slave battery with wires to the clamps so that the car never loses power.
