Thread: EAS emergency air-up kits

In my experience, when a serious fault is encountered (compressor, speed + height sensor etc) the car drops to the bump stops, not access. No amount of twisting of signals, sensors etc will lift it.

For those cases, I used to make an air-line splicing kit that allowed you to pump up the air-bags directly with an external air compressor, after first disabling the EAS system. This removed all points of failure bar the air bag itself. However, the supplier of my high pressure quick-fit connectors has gone under, so I'm currently searching for another supplier.

I presume physical evidence would exist when rods are fitted and removed (if only finger prints or tell tale very clean bits) and software mods must be evident if LR had to have a close look to ascertain acceptance of any warranty claim.

Has anybody had experience with LR with this or am I being a little parnoid? Or is that D3 owners out of warranty making good use of these seemingly great devices?

Agro,

There is no physical evidence once you have removed the GOE rods and replaced with the standards - even DNA traces wouldn't survive under there! So you can comfort your paranoia with that thought

I ordered push fit DOT metric brass fittings from Australia per the link below. These are the metal push fit ones with the little 4mm ferrule inside for reinforcement.

It is near impossible to obtain 6mm push fit DOT accepted fittings here in Canada or the States. Norgren does make them, but I think they come out of the EU as it takes longer to get them from Norgen than from General in Victoria. As best I can determine, the General supplied fittings are a Parker product out of a factory in Brazil.

The link has a couple of pdf's, a wall chart, and fitting catalog, that are both excellent. Better yet, it seems the fittings are in stock.

Thanks Bbyer, however those have a max pressure of 300 psi, a bit close to the system maximum - the ones I was supplied were 1500psi.

I'm hearing back from a potential supplier Thursday, so here's hoping.

Rick,

If I understand you correctly, you're asking about the effect of running a LLAMS/rod lift _plus_ the occasional 25mm lift you could get from the Faultmate?

A couple of things ....

Firstly, the +25mm lift from the Faultmate is vehicle specific - if your car has already been re-calibrated by LR and required a few height changes to be programmed in to be returned to level, you wouldn't necessarily have the full 25mm available at each wheel.

Secondly, there is a maximum height beyond which you cannot raise the vehicle. If you try to "trick" it into reaching that point or greater, whether by rods, LLAMS, or some combination, your compressor will probably cut-out due to overheating as it tries to raise the vehicle to satisfy the apparent sensor inputs.

With the GOE rods, when used in shortened mode, the new off-road height is roughly equal to the standard extended height (maybe slightly taller). So if your car now attempts to put itself into extended mode (due to grounding or bogging), there is still some lift left in the suspension, and the car will raise to what was approximately the old "super-extended" or "emergency" height.

What this means is that if you are in this mode (the new extended height), you cannot use the "5sec on the brake and hold the ride-height switch" trick to get any further raise. The car will attempt a lift and then give up. If you continually try, the compressor will overheat.

So using two mods in conjunction is not recommended, as this safety buffer (off-road to extended) would not be available.

Hope that's as clear as mud?

Gordon

The peak system pressures when an air spring is compressed is an interesting question.

I gather that while the air tank runs about 240 psig, the air spring internal pressure when the 3 is parked probably runs closer to 100 psig. The real question however, is what is the peak pressure when the air springs are compressed?

The fittings I was really trying to get were the Voss System 203 fittings which is what I believe Land Rover is using where the air lines connect to the block valves. If I am correct re the Voss 203, then the interesting note per one of their catalogs is the nominal pressure rating of 13 bar (~200 psi) for the Voss 203 fittings.

I am still trying to source Voss T fittings as I wanted to use the Voss System 203 T fittings to tie into the air spring lines. I figure that then I would not have to actually cut the factory 6mm nylon lines but could instead, effectively just connect in at the valve blocks.

I did not see on the Air and Hydraulic website that they carried Voss, but I think that I will contact them anyway as I have not had any success with anyone I contacted in the EU, Canada, or the States. I think Oz is so far away from everywhere that you have to be self sufficient.
