SOURCE: I have a 1999 Jaguar XJ8, there is a Check Engine

the gas gauge is not related, that would be a defective gas gauge sending unit in the gas tank, the check engine light indicates that one of around 200 poss faults has occured in the electronic engine controls, you will need to have the OBD 2 engine control system tested for the fualt code that is stored when the light is turned on.

SOURCE: Stability control fail Jaguar XJ8

this may sound crazy but what sort of fuel are you running? Try filling the car with premium 98 octane and run it - if you are running inferior grade or dirty fuel the throttle body sensors will register a differential in the burn/energy and throw a fault. The bad news is that a faulty throttle body will cause the same problem and cost a fortune to replace.

The resistor that controls the blower motor. it is a small gadget that has a 2 or 3 wire plug . Replacing the resistor should fix your problem. It is on or near the blower motor. Under the dash. Not easy to remove . But it can be. Please give thumbs up if helped.

SOURCE: My 2004 Jaguar xj8 will not release both latches

If your bonnet will not release, there is a rubber plug inside fender located up in
the wheel well under the latch. Remove the plug, stick a screwdriver up and pry the latch
back. The hood / bonnet will open.

SOURCE: cant get my 99 xj8 out of valet mode, and my trunk will not open.

There are Valet keys (often with a green knob) that will
only unlock the front doors and the ignition but not the
glove box nor boot/trunk.

When either the front door locks or the console button is
pressed, all the doors should lock. Likewise, when either
front door is unlocked, all the doors fuel filler lid and if
selected, the boot will also unlock.

Boot lock has three positions. Unlocked to the left,
automatic with the doors in the center, always locked to the
right. Simply remove the key in what ever position you desire.

The locks can get confused and not work correctly. Simply
sit in the car and manually lock all the doors. That will
usually get the locking module sane again.

Security is set. Could be one problem. Fuel system can do this, but rarely. Takes a scanner to see where to look first.

I need a locking fuel cap for my 2000 xj8?

The door to access the fuel filler compartment locks as part of the central locking system. If it is working properly, the fuel door is locked whenever the car doors are locked. However, if it doesn't lock when you lock the car, and you don't want to repair the central locking system (or part thereof), you will have to buy an aftermarket locking gas cap, since Jaguar doesn't offer one. You can find aftermarket gas caps at many online stores and catalog stores such as J.C. Whitney. Good luck.

XJ8 - central locking fails to operate on one door (driver's) only.

it may be the central locking motor on that door, but firstly try freeing it up, they sometimes get stiff and just need some WD40 spray all around the lock,mechanism and if you are able to get to the motor spray that also, you will have to remove the door trim to get to the motor its a fairly simple job. Once you have sprayed everything lock and unlock the door with both the key and the remote repeatedly.

Hope this helps

Can you give me the instructions for programming the remote for a 1999 Jaguar XJ8. Thanks! Alan Broyles

  1. Hold headlight flasher back.
  2. Turn ignition key to position 1.
  3. Flash headlights 4 times. Alarm will enter programming mode. This will be confirmed by "beeps" from the alarm and flashing led on gearshift. Program each transmitter (up to 5) by pressing the lock or unlock button on the each transmitter once. The alarm will "honk" when you press the transmitter button. The alarm must honk 5 times to complete the programming. Therefore, if you are only programming one transmitter you should operate the transmitter 5 times. If you are programming two transmitters you will operate one transmitter twice, and three times on the other. For five transmitters you will operate each transmitter once.
