Thank you for the information. We are confirming that there was not a mistake with the type of shocks sent....sports or comfort. But, it sounds like there is a possibility that it is in the hyper extended mode. (I know that we have already checked the height, etc., and that is okay.) How do we check to see if it is in the hyper extended mode???

To anyone that's interested
I found this page that tells you exactly how the XJs air suspension works.

Hello all..............
I am new to the forums and wish to introduce myself. I am a 59 year old male retiree in Houston, TX. I own a 2004 Jaguar XJ8 and like others I am having suspension issues. Please give your thoughts if you will.
First Mechanic:
One morning I saw the front driver's side of car was low to the ground(60,000 miles). Air suspension fault was showing. Drove it to my mechanic and he replaced both front air springs with Arnott struts. When he was finished both front and back springs on driver's side were down. He didn't know what was wrong.

Second mechanic:
A friend told to me to take it to his friend who worked on high end cars all the time. He got it up and it worked well for a week then the whole front was collapsed. He had kept my car for a month and I could tell he really did not know what he was doing with my Jaguar so never took it back to him. Bad experience.

Third mechanic:
Had it towed to a "Jag only" repair shop. He got it up and I drove it off and within a day it was collapsed again. Had to have it towed back and he claims I had a leaking air spring. It was returned to Arnott and a new(rebuilt) spring was then put on the car. Within a day the front was down again. I was able to drive it back to him this time. He pulled the air springs, tested them, said they had been leaking at the fittings where they are "aired up". Wrapped Teflon tape around the fittings and said everything tested good. Reinstalled them, pumped up the springs and gave the car back to me. Drove it home. Three hours later the front dropped 1 1/2 inches.

I start the car up and air springs inflate, the suspension fault indicator light goes off but after driving the car for say 15 minutes or so the indicator light comes on again. After shutting the car off the springs drop again.
The mechanic keeps telling me the problem has to be the air bage leaking but I just believe the system is more complicated than that. Something else could be wrong?
Your thoughts and suggestions to me??
Thank you for any replies.

Welcome to the forum, Geo. This is a REALLY GOOD post with lots of good, detailed information. My only experience with the air suspension was a leaky air spring and resultant fried compressor relay which was successfully fixed by a Jaguar dealership. A bit spendy, but it works fine now.
You've come to the right place for advice. Lots of real knowledgeable folks here, and I look forward to hearing what they have to say about this. It sounds really perplexing.
By the way, you should wander over to the New Member Area and post an introduction so other folks can say "Hi."
Cheers,

Yes, I have learned that! Each mechanic I went to said they knew how to repair those systems and had the software to analyze them. I guess my next stop is to a Jag Dealer. Seems as if that's where I should have gone to begin with. However it would be good to get some possible causes from knowledgeable persons on here before I go. I have already spent quite a bit of money without any return. I am sure you understand what I am saying. Guess it will take a while to learn of a good repair shop in Houston. I'm trying

Thank you for the link. I was having trouble locating it.
Still trying to learn how to navigate this site. I am so happy to have found it.
Un-diagnosed and wrongfully diagnosed auto issues will drive a sane person crazy! And just as worse, are the costs associated with repair that is not needed to begin with!
We have all experienced the above in our past so I know you understand.
Thanks again for the link.

Thank you.
I'll call as I definitely need correct diagnosis and repair.
I have already spent far too much money (close to $3,000) to resolve my air suspension issues. I know these previous costs are mostly just money down a toilet and that they in no way affect my continuing costs; except that, my recent expenditures have done serious damage to my spare change available for additional service. Having said that...........................
Can you possibly give me a rough estimate on what costs I may be looking at for "air tests" and additional diagnosis?
If it is not an air spring leak then what other components could cause the Jag to drop??
I love my Jag and would wish to be able to enjoy it.

Hello
If you have read my original post you understand why I was beginning to think that there WERE NOT any "good techs" in Houston.
Grrrrrrrrrrrrrrrrr

When it airs up, measuring from the pavement to the bottom of the quarter panels it measure 28 1/2 inches. But will drop 2 1/2 inches while parked over night.

" Drive the car around for a few minutes, park it and let it sit overnight. When you park it, leave the battery disconnected so the air suspension module doesnt tell the car what to do. Measure the height when parked.....then check again in the morning. If one corner is much lower than it was the night before, then likely you have a leaking shock."
I think I read the battery is in the truck somewhere.
