Your car does not have plug leads so that will save you a job,the spark plugs are fairly easy to do tho.
Open the bonnet,either side of the engine at the top there are 2 black covers bolted to the top of your engine,bolted to those are 2 smaller covers,remove the 2 smaller covers which will reveal your ignition coils,remove the ciols and your spark plugs are there.
You will have to remove the air filter assembly tho on the right hand side which is easy enough,remove the bolts from pipe at the rear middle of engine,undo the clips which houses the filter and disconnect the engine breather pipe.Re assemble in reverse order,
N.B the spark plugs dont want tightening too tight..or too loose,when the plug nips up just give it a little nip again..GOOD LUCK

i also have the same problem regarding the oil leak. this is due to the spark plug gasket leaking and you will need to replace them. they are circular gaskets about 1.5 inches across that fit to the underside of the rocker covers and prevent oil from seeping down the long spark plug hole. when i investigated my leak i assumed it was just the rocker cover gasket that was leaking but once everything was removed it is obvious.

SOURCE: Jaguar glow plug problem
The Glow plug coming on, and the car going into limp home mode, is a default safety feature that occurs when the engine management system picks up any kind error message from the many sensors now used on the car.
I've found the glow plug light problem with my Jag, it was the air filter. Apparently Jaguar servicing change it every 3rd service (not a good idea). I changed mine, it is a new car. I had the EPR valve cleaned and a major diagnostic carried out by a local garage (who had the Jag diagnostic software). It turns out I also need a new Turbo; the actuator is sticking (£759.00 plus 3 hours labour). But hey, the main limp home mode problem is fixed and I can drive my Jag confident it will accelerate when press the gas.

You can check the input voltage at each coil. This way you make sure you have the proper amount to operate. Disconnect the six ignition coil connections. Turn the ignition key on. Check the voltage at Cyl #1 B/Y wire, Cyl#2 B/U wire,Cyl #3 B/O, Cyl#4 B/G, Cyl#5 B/R, Cyl#6 B/W and ground. It should be 10.5V or higher. If not,you need to find the cause of the voltage drop.
If ok, you can test the resistance of each coil. At the coil,measure the resistance across the primary windings.It should measure between 0.50 Ohms ans 1.00 Ohms.
I hope this information is helpful.If you need anything else,don't hesitate to ask. Thanks,Chuck.
