Yeah definitely, I haven't had a chance to check the connections to the EAS controller yet but I'm thinking about taking the module out and seeing if there is a landrover specialist near me that could test it on another car, would save me allot rather that replacing and and hoping for the best.

Update.....
I have recently replaced the EAS module was really simple, my fault has cleared but I now have a missing calibration fault.
I would love to callibrate it but my Gap tool i recently purchased doesn't have the calibration menu?? It also says limited at the top of the screen. I was told it was completely unlocked when I bought it, seems like I can't get that option. Has anyone else seen this on the Gap Tool?

Have you registered it and assigned it to your VIN? Where did you buy it? Only time mine is limited is when I am reading faults for someone else since their VINs are not assigned to my LR3.

You were 100 percent right, I bought it used but near new with recipt but it was not transferred to my vin. I have now done that and was able to callibrate now and clear fault.
But there is something strange going on now.....
When ever I try and lower the vehicle is goes down a little then says in the dash vehicle in extended mode, then just keeps jacking the are end up really high.
I have tested all the inputs and outputs to make sure everything is the right way around with no luck.
Any ideas? im getting over this, feels like one step forward 2 steps back lol.

Do you have an AMK compressor installed or a Hitachi?

Sounds like your system isn't venting properly. If you have an AMK there is a solenoid valve you can replace; if it's the Hitachi the dryer can be replaced. Cheap parts and should solve your issue, but I may be wrong. I'd need to see the fault code, too.

Yep I think your on the money, I feel like its the rear that isn't venting properly its weird that it has only started since changing the aes module but properly because the air suspension has not been used properly for a long time.
How do you tell which compressor i have? Does it say on it?

Well...the AMK is bigger and is mounted on an angle bracket with three legs with springs on them. I know that much. I don't know about part numbers or labels. Also note that sometimes after the desiccant breaks down it gets distributed in the EAS system and can clog up a valve block.

I have recently purchased a Land Rover Discovery 3 2009 diesel model. It had a intermittent suspension fault on the dash which I knew when I bought it. I would love some help and advice to determine the source of this problem because I love this car and would love to make use of all the features.
The problem, so I have ruled out air leaks by lifting it up and taking measurements and leaving over night successfully no drop in the hight at all, the compressor does function when the fault isn't present it will work as per normal turning on and off .
The suspension fault comes on 90percent of the time and generally it will work fine first thing in the morning but after a short drive I get the amber then red light saying suspension fault limited to 30mph but I can always go faster than that, I doesn't affect the driving at all just annoying hearing the beep all the time.
Cycling the power doesn't make any difference it comes straight back.
I have tried a used compressor module to see if that's the issue but made no difference, unfortunately I don't own a scan tool or so can't see anything specific for my car suspension.
Any help or advice would be greatly appreciated, im happy to give it a go to fix myself I enjoy working on cars and love to learn more about these cars.
Simple maintenance would do, pull out air pump change desiccant in air drier , pull out valve bodies fit new O ring kit , sluggish air movement will throw these fault codes !

Thanks for the comment, I have a new AES module coming from overseas, mine has as internal fault. I was able to confirm this using a borrowed module and my Gap tool.

Recently brought a LR3 ( two years ago) lots of faults ! , water leaks, electrical , transmission and suspension most problems were fixed with maintenance (hard and easy and a few dollars for bits ,parts and kits) and a Nanocom (a OBD device)

Totally agree! Good maintenance is key to a reliable happy Landrover. We bought ours really cheap because it had the air suspension fault and some other tlc issues but with some time and effort its now a great family car. Well worth the effort.
Whats a OBD service?
