How long ago did you buy the car? If it was fairly recently, you could try and push the dealer to replace it at their cost

This is probably a wiring issue. I have never seen an issue with the AMK compressors.
Be aware that they will have to do wiring checks, and if the compressor is not at fault, you will be liable for the diagnostic/repair costs My D3 Build Thread

How much would a main LR dealer charge for diagnostics?

Fault code C1A13- 64 pressure not decreasing when venting gallery can be set if the new compressor was installed without updating the software.
I have also seen this code when a new (3 month old AMK compressor) started to display it. After checking/overlay the wiring & check the rest of the system out & contacting Landrover technical about a possible software issue, putting on another new AMK compressor sorted it.
I also know of another, with similar symtoms.
I have a feeling this may be a software issue, as the new compressor draws half the amps on the exhaust valve circuit, I assume the new software has been written to allow for this, but maybe when the compressors have been in service for a few months they might fall outside spec & flag this code..... too early to tell, but no doubt there will be a raft of C1A13-64 codes soon if this is the case. It could be just the odd AMK compressor at fault. But the one I tested the exhaust valve was working & dropping the pressure, it's just the software flagged a problem as it wasn't happening as quick as it would like.

Thanks a lot for your input Steve, I have just spoke to the service manager at Ripon land rover and after relaying your message has said that it is quite feasible. The service manager also informed me that there is a new version of the AMK compressor that they have just received in the last week!

Tried that and they told me that unfortunately due to the age of the car they couldn't help me out this time, (or any other time)  . The really annoying thing is that my D3 has only done 30,000 miles

Having just had the AMK compressor fitted - would there have been a software upload to go with it , reason I ask is having got my D3 back after 1 month off the road compressor fine but ..... I now have no cruise control . Seems its been disabled so assuming someone has been tinkering in the car puter and caused the issue
What do we think ?

The suspension software wouldn't alter anything else on the car. To upset the cruise control the engine software would be the one. But the only time I have seen that cruise deactivated is if you reflash the engine & the car has just had a cruise switch fitted (not activated in the ccf), and this can knock it off, as it was lucky it was working before.
Maybe there is just a fault with it preventing it from operating.
Regards
Steve

Hello. Correct, the compressor will run using the old software but you it will be susceptible to the following exhaust valve fault. C1A36-01.

Sorry mate, this is simply not true

Ive been running the amk for a year now on the old software and still fine. Yes once very rerely i get a fault when going to access height but it clears with a quick switch off and back on. I rarely use access height anyway. craig.

I had warning light this morning and car wouldn't rise. Diagnosed as a dead compressor. The guys seem to know their stuff.
They said there has been an updated compresser and need to update software via auto logic. Does this sound like I'll get an AMK type or has there been other changes since this thread?
Sounds like warranty direct are playing ball tho thankfully.

Here in the US all the dealerships switched over to the new AMK when replacement needed even if they had the old Hitachi on the shelf (according to friendly local parts counter man). So most likely I would think you're going to get the AMK.
There was an update software for the Hitachi unit which also included a replacement relay....
There have been several recent posts of folks curing the "pressure rises too slow" issue with a refurb or replacement dryer. I managed to get a good price on the AMK though and fitted it myself with the aid of a spanner friendly neighbour who had access to a lift 
Updating the software took about five minutes with the BBS Faultmate MSV. A dealer would probably charge you an hour. They like to round things up like that.
