Why is my Jaguar S-Type going into limp home mode?

My Jaguar S-Type has started going into limp home mode. It usually recovers after switching off and removing the key from the ignition. I suspect some form of electrical/electronic problem. Any ideas?

Likely to be a bad connection inside one of the multipin connectors. Maybe moisture ingress. maybe verdigris. Maybe a corroded pin.
