check for a bad fuel filter or a leaking rubber line after the fuel pump . To dump that much fuel so quickly ,the fuel pump is pumping to a broken /split hose or steel line.

"The message relates to the CAT(S) system, (Computer Active Technology Suspension), which changes the shock absorber settings front-rear and left-right between Soft and Hard based on inputs from various motion sensors."("2004 Vanden Plas air spring replacement - Jaguar Forums - Jaguar Enthusiasts Forum," n.d.)
