Is there a Vin number or date when AMK compressors were installed from? I have a 02 2011 TDV6 D4 and not sure what is in it. Hope not to have to remove the cover to find out.

Our D4 is 07/2011 we had Hitachi compressor replaced with the AMK updated compressor.

Pretty sure Aussie delivered 2.7l didn't receive the AMK compressor, only the 3.0l, our 2.7l D4 was one of the last in Australia, 2.7l was discontinued in the UK in 2010.

Remove the plastic cover and check. If its got a red and a blue air connectors it's a Hitachi. My D4 MY11 3.0 SDV6SE has the Hitachi unit

So a late 2014 Disco HSE would have an AMK compressor?

Definitely, anything 2012 and up have an AMK.

I’m sure I recall reading some that had AMK replacements under warranty were switched back to Hitachi. Best to take a look to see what you have.

I have two MY12 D4 TDV6 here with the 2.7L TDV6 engines that would say otherwise...

I've only had cause to investigate one of ours air compressors and it was a Hitachi unit in our 2012 model - perhaps you mean anything later than 2012 and up have an AMK? 2012 might be a bitsa year where a bit of both were used and so needs to be examined case by case individually.

Always exceptions to the rule.

FWIW our 2014 poverty pack 3L TDV6 D4 has a Hitachi compressor.

Compressor lower plastic cover removal is 1 hex bolt, 2 torx screws and 5 clamshell clips (about 1 minute to check properly)

This morning I replaced the compressor in my 2012 SE. It was a Hitachi which I got from Island 4x4 as it was what was fitted originally. Top bolt was a pita but is now slotted if there is a next time

Today I pulled my old Hitachi apart and found that the desiccant had powdered and was blocking the flow.
Repaired it with a repair kit for next time. Simple job and does not take very long. This is the original compressor and I have done 256,000 km with it.

Recommend at same time pull the cover off the electric motor and give both halves a good blow out and blast out with contact cleaner spray like Carby or Brake Cleaner. It’ll be full of carbon dust and appreciate the refresh also. Probably help it run cooler.

4 screws and lift cover off.

This clean. It’s black when you open it.

Run a bit of wet and dry sandpaper on the rotor where the brushes contact.

Carby cleaner will strip the varnish off the windings, contact or brake cleaner ok if you blow it off straight away

Handy to know that as I do use BC 99% although have a tin of CC for its intended use. It evaporates very quickly both of them and both clean degrease dirty parts effectively.
