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 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.
