Hi All:
I am in the midst of finding the just right XJ8 car and have found that I do not know what the differences would be between the the XJ8 year models that I am considering which are: 2004-2007. Not interested in so much in body or design detail differences, but more if there are differences in any safety components (i.e. number of airbags) suspension components and of course the different "options" that might be available.
I would appreciate any detailed help with this or a link to where I might the answer.

No major mechanical changes were made to these cars during their production life. There was a small restyle in 2007, but that's about it. In sales terms the car was not as successful as Jaguar wished.


You're better off trying to get the best car you can regardless of year. This means well-maintained and (hopefully) cherished by its owner.

 

Check out Wikipedia for some good background information

2004 XJ8/XJR specs are shown in the attached complete with options breakdown

 

I forgot to mention that a diesel version was introduced in 2005, but as you're in Texas it's of no relevance as none were sold in the US.

 

Hi, I recently purchased a 2004 XJ8 with a/c troubles. The car had sat for 6 months due to air suspension issues and the a/c was non-functional. I checked the system pressure and found that it was empty. I vacuumed the system and added refrigerant, but it only took about 6 oz. The compressor was not working, it seemed. My first check was to read the voltage on pressure transducer. I read 5.000 volts in and 1.223 volts out when the system had about 70 PSI on both the high and low pressures measured on a manifold. I removed the transducer and measured the voltage at ambient and it was 0.500 volts. What I gather is that voltage and pressure are linearly correlated, since I have 0.727 volts increase when the system is pressurized to 70 PSI. Anyway, although my transducer seemed to be operating properly I decided to swap it out with another and this is the point of my reply here. I searched the web and was completely unsuccessful at finding a new replacement. Fortunately, I found a seller on ebay that did not display a picture of the item, but it was supposed to fit my car. I received the transducer and saw that it incorrect and looked to be one for an X-type.

This is the exact same transducer that I found on my car

This is the X-type and S-type transducer
Above is like the one I recieved. Since they both appear to simply screw on to a schrader valve I decided to conduct an experiment, since it doesn't see to be possible to obtain a new transducer for the X350. I went to a auto salvage yard and looked for X-types and S-types (I also found that this same part fits a Ford Fiesta and is considerably cheaper) and found one of each. I also removed the round socket-style connector from the vehicle. I purchased all three items for just over ten dollars. Fortunately the wiring colors are identical, so no need to do any electrical testing. I temporarily wired the new harness into the system and installed the transducer from the X-type and measured the output voltage. It was 1.227 volts, very close to the factory device. So long story long, my transducer was fine and you can very cheaply replace the factory unit with one from a Ford Fiesta or a Jaguar X-type or S-type. Interestingly, both of the units I removed from the Jaguars say Ford on them.

Anyway, I just wanted to put this out there so you owners have another resource for a part that seemed unobtainable.
