D3 EAS air drier refurb kit - local source?

[nivekau]

Hi guys,

I'm getting a fault on my EAS which basically says the compressor can't fill the reservoir quickly enough and consequently the compressor is running more often than not.

I've removed the compressor and the air drier filters were quite clogged and some of the silica gel balls have turned to dust, so before I start looking at anything else I need to get new filters and dessicant.

Does anyone know where you can buy these locally? (I don't want to wait a week for them to come from the UK).

Thanks,
Kevin

Were you getting the 'vehicle raising slowly' message? I just saw that message in my RRS when my mate couldn't stop himself from raising and lowering it about 10 times within a five minute period.


I'm wondering if maybe the maybe the desiccant should be replaced to possibly prolong the life of the air compressor.


I don't believe my compressor has been done on my 08MY car with 200k, so I'm thinking I should start preparing for the inevitable.


Did you find it difficult to remove the compressor/desiccant housing?

[Epic pooh]

No that message is because the compressor is not intended for that sort of duty cycle in that short period - it just got hot.

That said, taking the compressor out and doing the desiccant is a pretty easy job - couple of hours tops including coffee.

My hitachi compressor lasted 7 years and had life left in it when I changed to the AMK compressor.

My D3 is doing the same thing very slow to raise . just putting off the new compressor , so the rebuild thing interest me
:D

Thanks to my archive of bookmarks, I present the instructions ... DISCO3.CO.UK - View topic - Suspension Compressor / Suspension error (http://www.disco3.co.uk/forum/post799075.html)

Happy reading !

Were you getting the 'vehicle raising slowly' message?

Sorry for the late reply. No I wasn't getting that message. I was getting a suspension fault message on the LCD dash display and another message about only normal height being available, and the orange suspension light illuminated on the dash.

My IID fault code reader showed a suspension fault C1A20 along with a message about the air reservoir filling too slowly.

The compressor is straightforward to remove. The only hurdle is the top bolt on the mounting bracket. It's a pig to get to.

Once you have the compressor out it takes about a minute to remove the air drier (remove 1 screw, twist then pull). To remove the air pipes from the air drier, press on the red and blue collets with a suitably sized spanner and pull the pipe out, it should come out quite easily.

When dismantling the air drier canister, do it in a plastic box or similar container, to catch the silica gel balls!

I ended up ordering this kit (http://www.ebay.co.uk/itm/Land-Rover-Discovery-3-4-Range-Rover-Sport-Air-Compressor-Repair-Kit-Hitachi/221401493317?_trksid=p2047675.c100011.m1850&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%2 6asc%3D20140107083358%26meid%3Dd5f18835e053456c994 e95a8d7c35c0f%26pid%3D100011%26prg%3D2014010708335 8%26rk%3D2%26rkt%3D10%26sd%3D111429581139) from ebay

I called a couple of LR dealers first and they would only sell me the complete air drier unit for about $300.

By the way, a few days before I removed the compressor I removed the fuse to stop it running (with the height set to normal), and I found the car drove just fine and maintained it's height. I realised then that I could drive the car without the compressor even installed, which I have been doing for the last couple of days.

Thanks. I didn't know those guys existed. Too late this time but I will def give them a ring next time I need something.

I have previously had to take my compressor out to replace the bracket and the hardest part I found was to take the input pipes out. In fact would not come out at all and I had to cut the plastic tube the get the compressor out. When it went back in I just used a piece of rubber fuel hose as a joiner.

Is my compressor still works Ok but did through up a fault the other day I was going to replace it with an AMK but they are still a bit expensive so I bought one of the kits you bought which arrived Monday. As my compressor still works and the kit basically re- rings the piston as well as providing the gel etc so I think it brings a working compressor back to "like new".

It only took 10 days and if you scroll down in the ebay ad they have a very good instructional video on how to do the whole job.

I think I was a bit lucky in this regard. My D3 is 7 years old, but I suspect the most off road it has done has been dirt roads and a few paddocks. Consequently I found the compressor was still quite shiny and new looking.

I've read threads on other forums where people have had to cut the pipes, but one person mentioned spraying them with some sort of penetrating oil, after blowing dust away with an air line.

Can someone explain what keeps the car at normal height, when the compressor has been disabled (fuse removed) or even completely removed from the vehicle?

Hi Nivekau,
The short story is that the compressor makes Pressurised air which is stored in the Reservoir Tank. The suspension uses this air when you change Height of the car or during self levelling. The compressor doesn't need to run again until the Reservoir Tank is getting low on pressure.
You can't raise the car without Pressurised air.

Thanks Richard.

I understand that you can't raise the car without the compressor, but the missing piece of the puzzle for me is what keeps the suspension at normal height?

My car has been without it's compressor for a couple of weeks now (initially fuse removed, then compressor removed), yet my car remains at normal height and seems to drive just fine.

Is it the air in the reservoir that is keeping it at normal height, or is there some other mechanism that keeps it there?

Thanks,
Kevin

Air is not leaking out of the system would be whats keeping it there:D

Yep that'd be it. More to the point with the fuse removed, then the system is not trying to level. So if it is at Normal height when the fuse is removed, then it should stay there.
If one corner starts drooping then may have a leaky airbag:D

I assume (and I am sure I will be corrected if I assume badly) that if you pulled the fuse at Access height then it would stay there.
Cheers
Mike
