Hello,
thanks for the quick informations.
I have big problems with my eas.
Valveblock and compressor i have repaired.
Now my Range is dancing in the front- i have to recalibrate the system, but that is the last work i have to do.
I will do that on weekend, but before i have to find a leak, maybe i have one!
Yesterday evening i make an other test, because the Range goes ever over night in the rear down. In the front not.
I take the 2 airlines from the rear airbags out of the valveblock and put on the airlines some bypass valves. Then give 55 psi on them. The Range goes up. I put down the pressure to 50 psi and the Range was on standard high.
I spray some soapy water on the airbags and then i see some airbubbels!
After that shock i do more pressure in the bags, around 80 psi, and the Range goes up a little bit over the high level. I spray again and wait until today morning. In this morning i see no bubbles- what that?
The airbags, are they ever 100% airproof or not? Do they need a mininum pressure to be proof? On the picture, at the yellow line, the bubbles come out.

System runs at 140psi + - 7 psi so the maximum you could possibly have in there with the boot full of bags of cement and five bloody great fat passengers is that pressure. Realistically thought it will be nowhere near that. Only way to find out is to attache a pressure gauge in the line and read off that. Pressure will change as vehicle is loaded. There will always be slightly more in the front because it is, in unloaded state, heavier than rear. Condition of bags has no effect on how much pressure it takes to raise vehicle to sensor preset. An old weak bloated bag needs more volume, but the pressure required does not change. I would guess at around 65psi rear and 75 psi front in high mode. But that maybe way out.

If you put 80 psi in the rear bags and extend them that far i would be absolutely bloody amazed if you did not have a slight leak.

Hello,
please look to the picture- there comes no airbubbles out of the airbags!
The pressure is now- 5 minutes ago, 75 psi. High (offroad) position!

Martin think you are getting a little paranoid about leaks. Some leaking is normal. Land Rover say no more than 15 mm height lost in 24 hours. Your dancing will be more than likely a height sensor giving the same reading in several places. First of all with vehicle on level ground set the standard height 470 mm from centre of wheels to wheel arch's all round and see what you get then. What was wrong with suspension before you repaired valve block?
@ wammers
Thanks for the information, that an very little leaking is normal.
This information is new for me. I feel better now!
The whole eas story started with the compressor, because he was running mutch. The other problem was, that the Range goes down over night.
The informations about this problems which i find, tell me- repair the compressor and the valveblock.
The dancing symtom i registrated after i had have all parts repaired.
But i think the dancing was before- i do not registrad it before, because i think that that is normal, when the car goes sometimes up and down.
But now the Range goes down and... you know my problems.
But i like my Range!!!

When you come to a stop and the speed falls below 1 mph both front valves open to equalise pressure across the axle, if one side is higher than the other this will cause the car to drop slightly. There will always be more pressure in the O/S than the N/S because the vehicle has self leveled to allow for the weight of the driver. So if your O/S is a little higher than the N/S to start with this movement will be more pronounced. As the pressure equalises the car will drop then the car will rise to the sensor settings. This will happen every time you stop in traffic. If you have a sensor that is not giving solid reads but the same in several positions this will cause the vehicle to go up and down. As the system attempts to adjust the height. But it can only do this untill the compressor starts as no exhausting of air is possible with that activated, as the exhaust tract is close by high pressure air acting on the bottom of the diaphragm valve and closing the exhaust port. The vehicle can only go up with compressor running it CANNOT go down. So if some people have dancing with compressor on they definatly have a leak in one of the front bags or air lines.
Under normal circumstances maybe. But with 80psi in and blown up to that extent it's a miracle if air is not forced past the bead. Extended like that the air is trying to force the bead off the piston.

They go that far articulating over rough ground, would be a bit iffy if they lost air whenever fully extended

Just depends on the quantity of air you are losing. A few bubbles at extra extended height (as in Martins photo) is acceptable were the bags are being forced from the piston by air pressure.
Unlike a tyre there is no bead as such for the bag to push against just a groove in the piston the bead on the bag sits in. In that state of extension the air is trying to lift the bag out of the groove. As i said before it would be a miracle if there were not a few bubbles.
Also to add to this when they are articulated over rough ground they do not have 80psi in them only the expanded normal pressure air.

Hello,
yesterday i have cleaned the yellow line at the rear air bags (look photos). There was some dirt from the last greenladings.
Now my range goes down over night 1,..cm.
Wammers inform my, that an sinking of 15mm/ 24 hours can be.
I feal happy now and thanks to all for the tipps and information, specially to wammers, Datatek and rewmer!
With the recalibration of my eas system i inform you when i have done that,
because this weekend i have no time to do that.
