20 Most Recent 2004 Jaguar XJR-Series Questions & Answers


if your in doubt about the functionality of the suspension system a quick way to check and see if the static pressure system is working properly is totake a floor jack and raise up the opposing side that you have questions..The system stores 228ps in the retantion tank located under the spare tire.As you force the air to one side the recycle valve will release the air to lower the cars' body.You wil hear it come out,then lower the jack,then the air from the tank will refill the lost air....Turn on the car to initiate the air pump to refill the rear tank,you should feel the car raise up in the front evenly.Last but not least my suggestion is if you think another shock is leaking you can 1st check the caping on the shocks...at times they will leak slowly on the caping...it will start as a weeping leak and you cant hear it....you can get some soapy water and lightly spray it around the enter deck mounts location under the hood where the air lines feed into the shocks...if you see air bubbles,then you can easily pack a towel in the leakage until you find a used shock or rebuilt one off ebay....But you fault light wont display a mil.The fault light only comes on when pressure is lost from the shock,or a static line has failed...causing one shock to lower to be lower..The CAN will trigure a fault code as the sensor detects body uneveness..Usually when this happens you will see a fault code,but I doubt this is your issue.

has someone done some mig welding on your car and not disconneted the battery? if so its blown all the modules on the car ie blown its brains out. good luck

a dying or weak battery will also cause this. When the various electronics in these cars begin to do weird or unusual things, the first thing is always a weak or dying battery. God-Bless! put a good battery in it to see if the beeps go away.

Hi Manuel:
Is it possible to open the hood?
If so, you should be able to attach jumper cables (Alternator or Relay?) to get the switches powered up. I'm assuming the trunk latch is electrical.

I had the same issue...I went to Auto Zone and got a diagnostic...Came back that mt Throttle Position Sensor was faulty...However after taking it to the dealer, and paying 135.00 for their diagnostic...You can't simply buy the sensor. You have to buy a new Throttle Body at 902.00 + Tax. I hope it's not your problem, but go get a FREE diagnostic first.

For some cars when the brake light comes on it means that the brake fluid is in the reservoir is low. Check and refill.

2004 Jaguar... | Answered on Nov 16, 2012


You may have a fluid leak. The pipes are prone to leaking on that vehicle. The power steering top up reservoir is under the hood. Refer to reservoir caps for indication or owners manual.
