The XJ (X308, 1998 to 2003) is the first V8 XJ, using 3.2- and 4.0-liter AJ-V8 engines and a supercharged 4.0 in the XJR.
Your 1998 Jaguar XJ V8 is from the XJ (X308) generation, which covers model years 1998–2003. 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 1998 vehicle the 10th character of the 17-digit VIN is “W”. 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 28 years old, a 1998 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: 1999 Jaguar XJ V8, 2000 Jaguar XJ V8, 2001 Jaguar XJ V8, 2002 Jaguar XJ V8, 2003 Jaguar XJ V8.
