Help EAS issue :-(

Hi Folks, a while since I have been on, sorry.......

Got a problem with my 94 Soft dash with EAS. I hope someone can help.

Yesterday I changed the OSR air spring. Jacked up and put the rear body on stands and jacked up the axel to load in the new spring. All went well and it went to ride height when started. However, there was then a hiss by the new spring. Off side only up in the air and I checked the hose, all seemed ok, so wheel back on and started it up. Nothing, didn’t rise at all. Pressed the up switch on the dash and the ride light comes on - any ideas..

If I'm reading you correctly you only jacked up the o/s when changing the airbag. I'd be inclined to check the height sensor linkage or the air supply pipe isn't seated correctly, other than that I can only think that maybe you've damaged a height sensor by allowing the axle weight to pull on it.

Oh..... you did have all the doors closed while trying to inflate the airbag ,didn't you, including the tailgate???

Thanks so much for a reply zzr1200,

I jacked up only the O/S to check the connections after the first start up indeed. But it was on an axel stand with a jack under the diff. The sensor didn’t really take a great deal of weight. I had all doors shut too. I’m very suspicious of of the connection to the top of the air spring. The old one has a black insert, but the new one has a brass one, which seems to move in and out very easily. There is the original dust sleeve which I re connected. Do you know the procedure for connection – I might have done it wrong

Cheers Owen

Its possible that the "o" rings have been left out of the coupling or the pipe is not seated correctly, have you looked at the suspension info on the rangerovers.net site should be of help to you, feel free to ask any more question if you have already been there.

Air Spring Replacement

Thanks again,

The link only discusses the P38 :-( which is slightly different. The top of my spring, I guess, literally you just slide in the pipe until it stops? The pipe then can move back and forward (2-3mm) with the play of the brass bit. But if the bag has a poor seal (leak) and the valve block tries to inflate but doesn’t have a return pressure it wont go to ride height, but stop altogether. Will this then go to a Hard fault? Am I doomed to the stealer for diagnostics, even if I take apart and readjust?

Folks, dose anyone think it could be that the ride height sensor needs re-setting after being mucked around?

Thanks

There probably are slight differences, but that section is listed for the classic air suspension as well. I personally would check and see if you have missing or a damaged pipe/connection O rings and check the height sensor.

There is information on how to do this on rangerover.net's site.

or

Disconnect the sensor's linkage start the engine and manually operate the sensor to see if the vehicle lifts/lowers or if any air comes out of the pipe.

Also if you search rangerover.net there is mention of someone making a new OBD11 cable that allows the free software to communicate with the Classic EAS system

To all, for everyone’s benefit.

To remind everyone my car is a late 94 VSE range rover Soft Dash - 3.9 on an M plate.

The old O/S/R air spring was removed successfully, and the new one fitted. The rear was lifted both sides in tandem (not to confuse the ride height sensor). The new air spring was removed again after a hissing was noted and the car was not lifting. On this occasion the car was only lifted on one side!!!!! (was in a rush).

The car then went to hard fault and wouldn’t do anything on the EAS (light on).

Re-inspection time. The new air spring was removed successfully. The rear was lifted both sides in tandem, the air spring was removed.

Both air springs were tested on a compressor with soap solution to look for leaks. The old air bag was perforated. The new one was fine. The compressor was then attached to the air line back to the valve block. Soap added and it had a small hole in it 1 inch from its air spring end. – It had been rubbing on the chassis somehow (repaired boot liner?). It was cut and put in a larger braided hose and the whole lot put back together.

The car was then started – but still nothing. I understand that the brain behind it runs in self diagnostic stages. After 10 mins it was working again fine and the EAS light had gone out. It must be noted that the car had not been moved for sometime and it was jolly cold (frozen system ?).

Hope this helps someone.
