2004 Jag XJR suspension fault
Guest
Posts: n/a
After starting my car, anywhere from the time it starts to 5 mins after start i get a air suspension fault light. sometimes it doesn't do it. after the 5 mins pass and no light, it won't pop again until i shut down the car let it sit and start it again.
A couple of times when it was really cold outside and the car was sitting overnight, it would be so low that a ride too low caution would pop. I drove it for a little bit, parked, turned off the car and let it sit. tried starting it and the car would raise and the message would be gone but would still have a air suspension fault message.
I figured out that if i start the car with the driver door open and then after i start the car close the door i don't get the message.
researched the possibility of the problem being a air suspension relay. bought the relay, but have no idea which one it is. i know its inside the fuse/relay box under the hood but don't know which one. i'm also gonna check any loose connections o the shocks. any other ideas?? don't want to take it to the *********** because i don't feel like getting my wallet raped. please someone send me the relay/fuse box diagram for the 2004 jag xjr

Like many others here who have posted on this forum who have air-sprung XJs (the aluminium model), you probably need a service-exchange air compressor, situated behind the front bumper. Cold weather apparently makes things worse when they start to fail. It's one of the few issues on these cars that regularly turn up.
I also think the compressor is going out. I have a theory that letting the compressor get too bad contributes to more serious faults such as failed air springs and damaged CATS dampers due to driving the cars with the air springs at too-low pressures. I suggest getting the fault code read at the dealer and getting it fixed right away. I just replaced mine assuming it was the compressor...I was right.
Hi I had the same problem with my '04 XJ8. Cold weather fault message displayed. Luckily I was covered under the extended factory warranty. Get the codes read. You can get to a one year, one vehicle subscription to Alldata that will give you repair proceedures, bulletins and wiring diaghrams. Good luck George
I had the same problem with my 04 XJ8 and I replaced the compressor behind the front bumper. If you are mechanically inclined its really not that hard. I bought my compressor from Arnott Industries, you can google them. They were the best price.
You can get from the left front, take down the splash shield and unbolt the front fender well you will see it there.
