My 2004 jag xj8 suspension has raised ...? What's this about & wont go down ??

your car i think will be the xj350 all alloy car with air suspension. the normal cause of this problem is one of the level sensors on the front and/or rear or the little straps that retain the link rods for the sensor atached to the suspension arm broken off

Usually between the frame and the rear axles. A lever type device, should be fairly easy to locate. Check that the compressor is building air pressure and storage tank. Air bags not leaking and etc.

Have a 2004Jaguar XJ8 with message air suspension fault. I have replaced the air pump and reservoir but still get the message. What can I do?

Many things will cause the air fault to come on...I have yet to ever see the retention tank ever needing to be replaced...But if or when it was installed the neg battery terminal should have been disconnected always.I assume the code c2302..Under the hood is a relay #4 on the passenger side ..check it and make sure the fuse is good.Second,the system has parameters in the air suspension module with regards to the time for compressor to fill the reservoir.
Something like 3 minutes to hit 14.4 bar. If it takes longer, the asm will store code C2302. Easy to diagnose. C2303 is more of a problem as it is for air leak. If you come out and see the car sitting on the ground, you may want to tow it. As long as suspension is up, ok to drive. Either way, take it in soon .

I live in south Fl, and when the temp goes below 65 a message appears Air suspension fault and the ride is very bumpy. When it warms up, it rides fine! Whats up?? Thank-you!

the only thing will cause the fault light to come on is the pressure in the retention tank located in the trunk underneath the spare tire...,once the pressure drops,then the suspension pump relay makes the pump refil the tank...the cause of this is usually a leaking shock...normally they will leak around the upper sign is that the car will be lower overnite then normal or if it sits for a long period.if the front is lower then its a front shock..the bumpy ride is the fault system lowering the car from the leak while your riding..

Air suspension fault light came on in my 2004 jag xj8. a day later vehicle to low light came on. watched the suspension and it continued to work with this warning lights on. a week later the right shock...

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 times they will leak slowly on the will start as a weeping leak and you cant hear 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.

2004 jaguar xj8 reads vehicle to low.. where do i put oil for the front shocks to solve this problem??

You can't add oil to the shocks. You may have faulty shocks but not likely. This vehicle uses a compressor and fills the gas shocks with air to adjust ride height. You could have a faulty compressor, an air leak in the system or the sensor which indicates the actual height is faulty. I'd recommend getting it diagnosed at a reliable alignment or tire shop. Sometimes scanning the suspension system may have a fault code that disables the system.
