The XJ (X350, 2003 to 2009) was Jaguar's first aluminum-monocoque XJ. It uses 3.5- and 4.2-liter AJ-V8 engines, a supercharged 4.2 in the XJR, and air suspension.
Your 2004 Jaguar XJ is from the XJ (X350/X358) generation, which covers model years 2004–2009. It is the first model year of this generation: the platform, wiring and many procedures changed compared with the previous model, so a manual for an earlier year will not match it.
Check the model year on your VIN: on a 2004 vehicle the 10th character of the 17-digit VIN is “4”. Vehicles built for North America always carry the model year in that position; on some European or Australian vehicles it may be left unused, so in that case go by the registration papers or the build plate.
At about 22 years old, a 2004 vehicle is in the age range where wiring, rubber hoses, seals and corrosion repairs take most of the work, and where original factory information is hardest to find.
Same generation: 2005 Jaguar XJ, 2006 Jaguar XJ, 2007 Jaguar XJ, 2008 Jaguar XJ, 2009 Jaguar XJ.
