Why would you go to an AMK when they are both as good as each other and with the Hitachi you can just buy a new compressor where with the AMK you have to get a fitting kit and then have a software update to get the most out of it.

I thought there was only Hitachi copies available.

No there are real ones to be had - a tad expensive but genuine AMK are also a bit light on the ground and even more expensive as many sellers try to flog off the copies.

What is wrong with your current one - I know you said it was recently rebuild so unless it has had a structural failure I would try a rebuild again. Rebuilding is generally successful - do you have the aluminium cap or the old plastic one as the plastic one is problematic. The exhaust valve is also an issue but in my case a good whack with a rubber mallet removed the crude that was stopping it from closing and all works OK.

On first starting the car for the past week the compressor ran for a few seconds and then I got a double message of Suspension Fault and Normal Height Only, but today it is Suspension Fault and now at access height with no compressor running. Probably didn’t help with a caravan on the back.

The other day for some reason upon starting the car it asked to select a height and when I selected normal it tried to go into extended mode, but it only stayed at Normal height and again came up with Suspension Fault.

Will get the codes read hopefully tomorrow as I don’t have an IID tool and start on the repairs. But I am thinking that now the compressor motor has stopped.

Ordered a complete rebuild kit from these guys. 4x4airseals.com Including aluminium cap
They have a good selection of how to videos
Delivery via Royal Mail was reasonable - about 10 days



other option is XR8

I bought a good 2nd hand new cylinder and conrod with piston through Andrew at 4x4airseals who has a small stock.

You can find them on EBay also.

How it came up is I wanted to put a new big end bearing in but Andrew said they way they are crimped in makes this not possible.

In the end my big end bearing was perfect so I have a spare on hand just needing the piston seals done.
