    L322 2011.
    So the event happened other day and managed to replicate it today.

    0FA28749-11A2-4A06-976B-0B15AF35D9E0.jpeg Oh you little devil;)

    So anyway managed to pull the code.

    RLM-Suspension

    • C1A20-64 (2C) Pressure increases too slow when filling reservoir - Algorithm based failure - signal plausibility failure
    Code was logged on the 29/8/19 so it’s taken 2-3 weeks to actually show a problem after it noticed the fault;)
    Also logged some data and it looks to be shutting down on overheat, which would tie in with the dash warning.

    So tomorrow’s job is lift the cover and check compressor details, then get on the case of a filter/drier kit and a compressor rebuild kit.
    Hope that’s all that’s needed. No leaks on the bags as she will sit at any height with no issue, leak on the tank side is possible. I don’t think likely at this stage as there always air in the tank to raise to high on start up (need high to get on/off our drive)
    Have also seen the filter/drier cap can develop a small crack, so will check that closely.

    Well we should count our blessings really she has played very nicely for us and we do work the EAS a lot.

    So after more than 10 years of no EAS issues I guess it had to come:D.

    Will update as I find all the great fun coming my way:eek:

    Yep I hope that’s all.

    Fuel how do you know we need fuel;) don’t waste fuel to drive there it’s 15mins away:D still loads of KMs left in there.
    Will be going that way tomorrow so will take your advice :)

    When compressor is over hot EAS is locked until it cools on the L322.

    Yep. Can see that from dash message, fault log and logs today on IID.
    So general consensus is blocked filters or/and worn compressor?

    After 10 years, I'd be surprised if there is not a leaky airbag.

    10years ago it was the P38 devil:) (1996 P38)

    Now it’s the 8 year old playing up:)

    No problem with levels/heights over time. But I will check as a matter of course:)

    Like the P38, the bags leak at different levels and in addition from the top seals at the front.

    I understand.
    The car can be left on High/normal/access and is not droopy the next couple of days.
    It will pop up to high first thing after starting (to get off the drive).

    At this time I don’t suspect a leak, but won’t rule it out yet.

    Ok so today had a look at the compressor.

    It’s an Hitachi one not the “better” AMK ;)

    While I was in there I sprayed some soapy water and it’s blowing bubbles from around the red & blue labeled pipes on end of drier:(, difficult to tell if it’s the collets or from where they reportedly crack, which is between the collets.

    Found a kit that includes a new aluminum cap so off to get the plastic flexed:)

    Will check bags at weekend when I can put it in the garage over the pit.

    Can you not just seal them up with something? See if it works

    Can then still change later if you want it immaculate :)

    The leak I am seeing in my opinion is small and not the reason for the fault. But it isn’t going to fix itself.

    To do that it’s got to come out of the boot, well to make it easy. If I am that far I may as well do the whole lot.
    Kit I found is £70 which includes a nice aluminum drier top with better collets.

    To be successful I would need at least to replace O rings in the collets, but.
    They are prone to leak around the collet and also crack between 1/4-3/8 between. So how to fix that if that’s the issue,
    I am tempting fate (and the wrath of M) if I tamper with it and have no spares available, as it is running at the moment just overworks the compressor, we should be good till I can get the proper kit:D

    The desiccant degrades and turns to white dust (as P38) which then restricts the air flow from compressor, hence the compressor tripping on overheat.
    But if I am going to get in amongst it, I will not mess about with half a job:).

    So look what arrived today.

    5DE0786B-9410-4A1D-8910-8A2B452B21A5.jpeg

    Ohh so excited I get to play EAS again;)

    Anybody with eagle eyes will see a problem:(

    Anyway got straight onto them and did live chat, it should be in the post today:)

    So now have 4 options.

    1. Do the work but not change the cap. Which means I will have to take it out again when new fitting arrives.

    2. Check the pipe size and see if the small collet on my spare P38 block is the same size and fits. Does it fit new fitting?

    3. Risk getting the old collet out and use, it’s plastic. Does it fit and if I break it I am up that creek. ( rule this out right now:D)

    4. Just wait for the proper kit to arrive as car is fine if we don’t change height much.:)

    So much fun too come, think I may stick with option 4 to prolong my excitement :)

    It’s a shame because the new cap looks really well made and a great upgrade.

    I waited for the bit to arrive before getting in amongst it. Came on Thursday.

    So today we get to play EAS.

    In with the new :)

    All done took about 4hrs with plenty of coffee and thinking moments;)
    Only 1 skinned knuckle so not bad going.
    Tested up and down a few times and all seems good. Soapy water and no bubbles, Will give it a few days then check the codes again see if it’s showing anything if not call it a good un :D.

    If anybody’s interested the kit came from X8R, very pleased with the service, and their no problem attitude sending the missing part very quick.:)

    Trouble is, it’s all hidden under the spare. But I know it’s there:)

    Thanks for the offer, but you will want yours one day when you go back to real comfort:). Then I can get back to my therapy :D

    Silly place to put it.

    I do look forward to the challenge. Will be few years away as I need both fuel pumps, maybe some other bits replaced and a nanocom before i tackle that particular project!
    MOT October - time to see if anything I’ve done was worth it :eek:

    Hope yours okay for the next 10years
