EAS Issues - ECU fault & ride height selector lights out

Not as much traction on RangeRovers.net

2005 L322 HSE with 118k miles
Cant seem to find any threads on this. So the full chain of events were:•2 months ago, Air Suspension inactive (read codes, cant remember exactly but something to do with overworking the compressor I think, so thinking leak somewhere)
•Clear code
•Code came back in about a month
•Cleared again, and came back in a week or so
•Next day or so, truck was dropped down
•Started it, Raised itself
•Turned car off, Left the door open
•Immediately left front drops
•Replace strut
•Raised itself but had gross leak in left front
•Removed fuse
•Took wheel off today, and fender skirt in anticipation of filling lines with air and tracing
•Got in car, saw it had Air Suspension inactive
•Put fuse back in, no lights now on rde height selector switch
•Started car, no lights
•Fuse in and out with car running, still no lights
•Read code even though its not saying "air susp. inactive" anymore, but there was a "ECU Fault". That all it says in the RSW All Comms tool. I saw about 50 other fault codes though for random things, cleared all those even though I had no CEL.

Still NO RIDE HEIGHT lights. I can pull the fuse, and push it back in and the lights will flicker very very quickly, but then out.

Does this sound like the EAS ECU is shot?? Reading several things it could be practically anything from a weak battery to a compressor to an ECU. Aghhh!!!!!!!!!

UPDATE: Ok, pulled the battery cables again, hard reset, pos-to-neg discharge. Air Suspension Inactive back on, read and reset codes and back in action! Lights came back on, and instantly car rises. That’s where the fun stops again…I still have the original left front gross leak to deal with. It loses air so quickly, that I don’t have enough time to remove the wheel and get under there to spray check. The bag is totally deflated by the time I do that and I can hear the air somewhere in the left front. So I started the car and tried to get it to refill but maybe it knows it’s on jackstands and wont pressurize. Is there a way to inflate the bags using either the All Comms tool or a manually by using an air compressor into the line(s) somewhere??

I've asked Storey, waiting to hear back...anyone else know?

You have replaced the strut & airbag? If so I'd be looking at the pipe conection to the airbag.

yes, replaced strut and airbag, left the old connector in the air line per all recommendations. Pulled the fender well out to get to it and so I just replaced the plug connection from the hose into the upper strut.

STILL LEAKING!!!!! Sounds like it's in the left front fender well area somewhere, but I can't take it apart and air up the system. I need to pressurize the left front with the wheel off and fender well out.

Any ideas how to do this? Does All Comms do this?

Possible issues are:

*my new refurbished strut is bad, at which point Arnott needs to send a personal mechanic down here to replace it. Can't imagine that's the case but maybe. Didn't see anything with soap test best then again I cant see in there that well with the wheel on.
*Valve not closing somewhere for left front?
*bad hose going to left front
*should've stayed a 1 rover owner rather than 2?

Refurbished strut, is it not a new strut ?
can you not raise the suspension with the engine running and feel around the air bag and connector?
As Datatek says, it sounds like you may have dislodged the connector from the pipe, on a dunlop strut you trim back the pipe and its a push fit into the strut and the connector is not designed to be removed and the delphi ones it says in rave to remove the connector from the old and put it in the new but i think i would be inclined to chop it off and push it into the new connector if that is where your leak is coming from

yes, the Arnott refurb ones.

So update#2, raised the truck and actually, the hissing is coming from the RIGHT front fender well, where the cross-over valve is located is sounds like. I plan to replace the right front strut tonight (hopefully), and peel back the fender well to see what's going on in there.

I had both front struts go one after the other, i have a 2004 and i also suspected the front cross link valve but i could very well be wrong but i dont think i had one as they were only on earlier models and it turned out to be my air spring on the opposite side. i would have changed both anyway.

you could always strip out the plastic guarding behind the wing and then put the wheel back on and raise the suspension but my money, although not a lot of money, would be on the right air bag

wish there was an easy way to air the system the wheel off. makes this soooo much more difficult.

There probably is but i dont know how, faultmate might do it but not sure about allcomms

Getting into the fender well cross-link valve area now to try and find the leak, and just FYI for those watching Storey's video on manual depressurizing...his truck is 03 or early 04 I believe. In the '05, the cross-link valve is under the truck, just fore of the air tank. BUT, behind the right front fender well (NAS) is a connection point for the left front bag. this is an inline air hose connector that resulted from a production change in '04 when they moved the cross-link valve. Seems to be a common failure point (reading on other forums). Part# is STC8580.

and for those of you tracing leaks out there, here's the money shot:

UPDATE: Another freakin' leak!!!!!!

5 days after getting it all squared away, no problems. Then I park in the garage and I hear pssssssssssssttttttt from the left front. Pulled the wheel off and the "new" (i.e. new from Arnott's refurbished stock) is leaking around the bag juncture seal. Sweet.

What's that melted blob ?

you mean in that picture with the soap bubbles?

that's the inline air hose connector that's behind the right front fender well...LR put it there after relocating the crosslink valve to the undercarriage.

arrr, bubbles, i see now

let my whole experience be a lesson to all of you!! geez, what started out as a simple hose connector leak turned into a 4 week ordeal whereby I removed, installed, removed, installed the strut twice, and pulled the fender well back at least 18 times, installed a defective strut that was unnecessarily purchased and now my wife has lost all faith in me and truck (which I'm pretty sure already existed prior to this episode).

Keep the truck and change the wife, cheaper in the long run.

i have always classed females, landrovers and possibly computers all in the same category of 'Situation will most likely feck up, don't try and understand why'

Dont worry, it's like childbirth, they forget the pain quick enough........
