Second AMK in 2 years!
Well after just under 2 years I've had my second AMK fitted to the car. The guys who fitted it said it probably failed as the previous one was fitted without a top cover! (always sounded noisy but now I know why!)
I needed it working in a hurry so opted for a new one from Duckworths, ordered at 3 pm yesterday (Friday) from the Boston branch, delivered by Martin on his way home (Top Man! ) Fitted by the Phil at Old forge Garage at Leadenham this morning (Always entertaining to see whats in their Shed! )
Stripped the dead unit to discover the Silica was like pale coffee granules and shrivelled up so going to chuck some new in there and test it, could be a handy spare.Must stop buying shiny toys....

Firsty thanks for an awesome how to! I had tried a refurb kit for the hitachi but didn't work out. I think the increased pressure after putting the new piston ring on forced a failure in the join between the dryer and the compressor. Anyways, got my new AMK fitted and very happy except for one thing. When I was fitting one of the pipes (the one that goes into the side of the compressor, the angle joint fell off! Surely this isn't supposed to be detachable. I tried to just push it back in but it kept falling out. Can't tell if it has snapped off or was glued before. I have glued it back on for now (super glue) and will chat to the supplier tomorrow but wondered if any of you had similar problems.

Also can anyone confirm definitively which pipe I am supposed to put the brass insert into? Read the whole thread and seems to be several takes on this. Is it the new long thin pipe (that replaced the one that went into the dryer) that goes into the compressor that needs the insert at the compressor end? And which way around? Scratch that last question. Just looked at the LR bulletin and it looks like you only need the brass insert if you choose to shorten the thinner of the two pipes at the back of the compressor.
Thanks

For anyone interested, the supplier are sending out a new unit so I can swap out the compressor. Mine is apparently not the first one to fail in this way. The parts shown in my earlier photo are definitely supposed to be permanently connected but allow rotary movement.
Also thought I would mention that mine too seems noisier than the old one. When I swap out the compressor tomorrow, I'll make sure the top of the box is tucked away behind the valve block bracket (as shown in the technical bulletin) and not tighten the centre bolt of the box bottom too tightly (as mentioned by someone else earlier). I'll feed back if they help reduce the noise.

Great write up thanks. I've just bought a new compressor for mine, and the kit came with the 3 captive nuts for the chassis. Just a pity I'd already ordered three new nuts as well!

Ok. My AMK has been fitted for a couple of years now. Has anyone else had problems with it yet? The other night, I got the warning, suspension raising slowly. With the Hitachi compressor, this is often attributed to the dryer becoming clogged. Does the AMK compressor have a dryer and does it need servicing like the Hitachi compressor did?
I did check live values with the IID and it showed the compressor temperature rising very fast, like it wasn't able to pump the air into the main gallery, indicating an obstruction, possibly the dryer, if it has one.
Your greater wisdom on this would be helpful.

Actually I answered my own question. Yes it does have a dryer and no, mine wasn't all clogged up. I did take it off and put the beads in the oven for 1/2 an hour just to make sure. Getting the dryer off is a bit of a fiddle and the screws are made of cheese, in typical LR style.
I actually didn't know I had an AMK until I'd got the cover off. The job was done by LR just before I bought the car. I'm sure what when I checked the software with the IID, it showed Hitachi software. However that software check was done when I first got my IID, 18 months ago. Today I loaded AMK software, so I'll see how it goes. The car doesn't loose hight or seem to loose pressure from the tank, so I don't understand why the compressor got hot enough to shut down. However the car has been unused for about a month so maybe the tank had lost pressure.

It should be noted, that of those compressors, they were both on Hitachi firmware...
My AMK was fitted Oct 2012, and has done 70k miles since fitting between its previous owner and myself, and had the correct firmware from day 1, with no issues (other than the recently discovered leaky air tank) My D3 Build Thread
my Hitachi compressor was swapped for the new AMK and the software was updated, but it often threw the "pressure not decreasing when venting the gallery" fault. Mechanic said it was a faulty compressor, warranty covered it and the new one has the exact same issue so it is obviously not the compressor.
It DOES vent on a rather random basis (fault absolutely clears IF I turn it on with the door open)...
Anyhow, today I checked the fuse box and discovered that the Fuseable link FL10 that is supposed to be a 60 amp yellow fuse, is instead a red 50 amp.
Was this supposed to be switched with the AMK or is my mechanic stupid and swapped the 60 amp for a 50 amp ?
Should I get a 60 amp right away???
unlikely to be a faulty compressor as this is the second AMK in less than 4 months.
My indy said the first one was a lemon, I changed it and seller said the compressor was fine but still helped me and changed it under warranty. Then this one throws in the exact same fault?
I will check the wiring because what are the odds of getting 2 faulty compressors back-to-back with the exact same fault ? It could be firmware as well... It wouldn't surprise me to discover that the firmware used by my indy is dodgy
my D3 is NAS, is that wiring supposed to remain on the UK NSF, that would be my driver side?
