Thread: Suspension Fault Normal Height Only

I want to add my experience with this warning have D4 MY10 2.7 and I assume the original compressor. I would get the warning every month or so sometimes often with activity.

I ordered this kit http://x8r.co.uk/index.php/land-rove...t-hitachi.html based results in this forum. Comes with great instructions both pictures, instructions and YouTube video.

I have just installed this kit and found:
Lot of mud inside the compressor cover. This probably doesn't help so mental note clean after playtime
Piston sleeves not to badly worn but I had it apart and had the parts so I changed them
I had white coloured desiccant seems the wrong colour but also some power in there I would assume to be broken down dryer. Due to the powder the filters surrounding the dryer get clogged. Changed all filters from kit and including new dryer beads.

Tips for pump removal:
I got the Aussie version of this set https://www.aldi.co.uk/en/specialbuy...-wrench-set-5/ to help remove the top bolt which is really hard to access - wratchet ring spanner was the only way for me. Also you can 'move' some of the air lines to make access easier as their holders are in 'slots' in the chassis - would have saved an hour on the removal had I realised.

So now time will tell but so far the pump runs and no faults despite some heavy testing use.

removed from here and started a new thread

You need to reset the steering wheel angle after a wheel alignment, if its out all sorts of things close down.

This can be done by the dealer or anyone with a suitable diagnostic tool, Nanocom, IID, etc.

I've just done mine with my Nanocom and would be happy to help, BUT I'm in Canberra.

Someone closer should be able to help or try this link Members with Diagnostic Equipment map (updated 1/2015)

The suspension fault/light/warning characteristics are typical of the compressor failing to sufficiently quickly fill the reservoir due to either a blocked air dryer or the compressor itself is failing. The next level of fault will be that it cannot get to normal height within its allowable time after which it will show the 50 kph only message and drop to the bump-stops. If this occurs then restart the vehicle and as soon as the suspension is up to height or as far as its going to go then remove the 20A suspension system fuse from the engine bay fuse box (3rd fuse from the front on the outside row) to stop it lowering again. Meanwhile don't use access or off-road height to keep to a minimum the work required of the compressor.

Last week I replaced my lower control arms.
All good, went for a drive and I got all sorts of errors including suspension ones and finally down on the bump stops.

Cleared the errors with my Nanocom and reset the steering angle sensor and all was well.

Then got a wheel alignment done, reset the steering angle again, and she now runs straight and true and knock free.

If yours has had a wheel alignment and the steering wheel was out of position, then it needs to have the angle sensor reset. If the dealer had so much trouble
I wouldn't be confident that they did reset it.

PS. The D3 rides soo much better on the bump stops than the P38 did!

Turned out that the steering angle had been reset; so moved onto the compressor which was almost dead so it seemed. With a new compressor all is good.

This thread was very useful to me during the week.

I have an 07 D3 on its original compressor. Started getting the 'normal height only' message. Removed the 20A fuse and was able to keep driving it for a couple of days (despite the warning messages on the dash).

Had the fault codes read and the air resovoir was filling too slowly - compressor on the way out as I had expected. In a way I always felt I was driving around on borrowed time with the original compressor and long trips especially were starting to worry me.

New AMK compressor and software installed and shes all back to normal. In fact goes up a little quicker than before.

Hopefully this one will give 10 years of good service. Fingers crossed.

Considering going down the same path. Haven't stumbled the 'results in this forum' relating to the x8r refurb package, but my searching skills here are 'emerging'. Any cues appreciated.

'Landyair' has an equivalent refurb package: Land Rover Discovery 3 4 Range Rover Sport Hittachi AIR Suspension Repair KIT | eBay

Interested in any comments as to whether one may be better than the other.

Understand that many hold the perspective of just replace the compressor, but finding it hard to shake the sensation that this is overkill (getting a low output fault recorded, compressor looks pristine externally).
