AMK Compressor replacement...EAS
So I am replacing the crispy Hitachi unit with an AMK, per recommendations from...everyone.
I have a SnapOn Solus Ultra but apparently it is not capable of updating the EAS software, which really sucks.
I just can't come to terms that the IID tool can do it, the RSW one can do it (I think) and the super duper expensive SnapOn cannot.
Anyone in NJ does this update?

I 2nd DavC, the IID tool will do it and you will be very happy with the tool. When I first bought mine I was very nervous because it is a lot of money for it. I bought the regular one and didn't even have it a week before I returned it for the Bluetooth one. If you do get one don't screw around just get the BT one.

My Hitachi is crispy...burnt. It did serve 9 years so not a bad thing.

I guess I'll just get the IID BT.
Meanwhile I'll have to take it to the dealer to get the EAS updated.

You can hold off a bit re software updating.
If you are going to purchase the IID, you can still install the new AMK and run without the update for a bit.
The safest way is install the compressor, let it fill the system to normal height and then remove the F26E fuse in the engine compartment fuse box.
That depowers the system and when air eventually leaks out, then put the fuse back in and the compressor will pump up the system again. The ride will be on the rough side as the left to right cross flow of air between airsprings will be inhibited but that would give you time to order and receive the IID and do the software upgrade yourself. Do not feel too hurt re your Snap-On; both the Black Box and IID are Land Rover specific; the Snap-On is more American than EU.
A new AMK does not quit immediately without the update but extended use of the AMK compressor without the update eventually results in compressor problems.
I presume that you have already got the AMK so the question of repairing/replacing the Hitachi is moot.
I ask as yes, I gather the AMK is better, and I suppose if, (no when), my Hitachi quits, that I will upgrade to the AMK rather than put in a rebuilt Hitachi. For me, it will be more a time thing - the AMK will be readily available from LR parts; a rebuilt Hitachi is more of an eBay thing.
My 3 is my daily driver; my alternate is my wife's 4Motion Passat when or it she will let me drive it - I am allowed to wash it however.
My view is that the Hitachi is not as bad as some think and the AMK is not as good as others might like to think. The AMK appeared as a result of lack of availability of the Hitachi due to the flooding of the Hitachi factory in Japan a few years back. The change was not because the Hitachi was costing LR too much in warranty service, just lack of availability to the assembly line.
While there was much initial bally hoo about how much better the AMK would be, time has not proved that to be the case - the AMK makes the Hitachi look not that bad.
Incidentally, often with the Hitachi, the problem is not the compressor but the air dryer - new beads etc are needed.

thoughts on the AMk
Below are some thoughts I have on the AMK and how it is different from the Hitachi. I wondered how correct I am however?
My primary thought is that you can run the AMK for some period on the old software without destroying the AMK.
I think the AMK has an internal temperature shutdown circuit, (rather than just a temperature sensor), and hence does not require the air system computer to merely monitor the compressor internal temperature sensor, (which the Hitachi has).
While the new AMK electrical plugs physically fit the existing plugs, I think you will note maybe two fewer conductors feeding from the new compressor plug that the existing vehicle harness plug connects to.
The software update hence tells the air system compressor not to look for non existent temperature sensor readings. I also expect the new AMK compressor has slightly different shutdown and startup pressures than the Hitachi and that revised info is in the new software.
There is also something about the exhaust valve plus the pressures being slightly different but have never seen anything from Land Rover either way.
This is a pretty good link re installation of the AMK.

I realize this is an old thread, but seemed the best place to post.
My 2006 LR3 is at 140K miles now, with all air suspension items original. Recently the compressor became very loud, and the suspension would drop around 80% within 2 days of sitting. While I don't have the current fault codes, I did find some leaks on the existing compressor. After a ton of research, I decided to replace the Hitachi Compressor with the AMK, along with all of the Valve modules. This will be the first time since buying the vehicle (new) that I haven't let the dealership do the work on it. However, it will go in for service next week and I will have the reprogramming done for the AMK..
Will complete the conversion this evening, having already prepped everything, including the removal of the top bolt of the existing bracket. That was a pain with lots of foul words coming out of my mouth last night... The new bracket for the AMK seems to allow better access IMO, and if nothing else, it appears easy to install the bracket first, then install the compressor. The plastic housing seems slightly taller, but I will have to measure to confirm.
On a separate note, I will likely install new struts and airbags in a few weeks, as 140K in mileage is pretty darn good for everything being original. Also ordered the RSW software today, as I will need that for the new airbags.
