are you talking about Motorcars kit? resistors to give the air suspension values its looking for.
you talking Air Ride the company? depends on what you want to do. if you want to raise and lower you could lie to the factory one with the correct voltages. And then scab in a air ride controller, go to larger lines ARB's new duel compressor 100% duty cycle and programmable controller.....

Nice to know how it's done, because the prices for these things are very high. I suppose if one calculates it as cents (or pence) per mile travelled, it is really pretty low, whatever !!
I looked on the internet, and found that a UK supplier has the front units at £640 each, but no rears. I hate to think what these are at Jaguar prices.
Land Rover owners are already well familiar with swapping out the air springs for steel.

I am pondering the swap because of the air susp fault I am currently troubleshooting.
Here is what I have done so far:
1. Power to and operation of compressor seems normal.
2. System goes up and down although slowly
While troubleshooting today, I was checking the tank for press, I had none, I had previously totally dumped the system to see if it would pump back up. I noticed that no air would come from the solenoid block with the tank line disconnected. IE the path from the comp to the empty tank was not opening. Should store around 200 PSI.
I think I will now remove the solenoid block and bench test it to see if it is working properly.
Any ideas are welcome.

Could you put a balloon over the tank line and go for a drive to see if it blows it up?

MK82,
Careful not to over think this problem. Most air suspension problems are the rt. front shock or the compressor or both. Given that you will have 1 hell of a time selling left over air suspension components, a conversion is not always the way to go.
You can get rebuilt shocks and new compressors at a good discount from Arnott. Doing the work yourself is not that big a deal. Or you can locate a good experienced indie serv shop and still be big money ahead. Slow down. The simplest most direct solution is usually the correct choice. Your location is not posted but I'm sure the Forum members can point you in the direction of a competent shop near you if that's the way you choose.

You do not get rid of the air suspension module on the conversion. It performs other functions on the car and has to stay in the network loop.
How are you checking pressure? Just because the pump is running does not meen its good. I have many pumps that run and cant fill the tank over 5 bar. No where close to system full pressure

I want to install a pressure gauge in the holding tank. I need a tee with 4mm quick connnect on each end and a 1/8 or 1/4 NPT tee. Or I could drill and tap the tank itself. The compressor appears to run strong but I need the gauge to test it right. I will also make a pinout box to test the solenoids.
Haven't found any leaks. Any one have a source for the air line fittings that goes on the air bags, solenoid block, etc. I think they are called Voss fittings.
I live in West Palm Beach area. Local Jag dealer wants $135 to diagnose which they will apply to any repair.
Who makes a scanner that will read Jag Chassis codes?

Today I installed a pressure gauge in the storage tank. I bled the system down and jumped the compressor and the solenoid to the tank. it pumped up to 175 which is the limit of the gauge in about two minutes. Seems fine to me. Yet I am still getting the air suspension fault. I think I will take it to the dealer and let them try to troubleshoot it for $135. I need the code or codes that are triggering the AIR SUSPENSION FAULT msg in order to go any farther. I also have been unable to detect any leaks either.
Does anyone know the factory suspension heights and how and where they are measured?
Edit: I found the ride heights.

MK 82, I have the AutoEnginuity PC based ST-06 OBD reader with Jaguar specific SW I can lend you. It has the CD-ROM with AutoEnginuity Jaguar Specific module, OBD connecter and USB cable. PM me with your address. Just send if back in a few weeks or a month and reimburse my postage. You'll need a laptop that runs XP or anything that handles USB 2.0

I used the scanner that Bob lent men today to pull the codes. All I got was the usual C1800 Plausibility error. When the car starts up the compressor runs but the solenoid to the tank does not open allowing the air in. If i jump the solenoid to the tank it will fill normally. This is controlled by the Air Suspension Module. As is the compressor and the rest of the system. No codes specific to it however. The mystery continues. The left rear bag will not pump up to the specified ride height. I will remove it tomorrow and check for leaks.

Well I am getting somewhere. I took off the rear shocks and the left rear is leaking badly. I will probably replace them in pairs. The rebuilts don't come with the accordion dust covers. Do you techs think they should be replaced? The r/r is OK but the l/r is badly torn.
I am making progress.
