    New bags, still got a saggy rear?

    So just had the bags replaced because the back end 'suddenly' decided it was old enough to get saggy.
    # One son filled the tank (L.R.=200lts), # two son took it for a run in the rough, and next thing saggy bum.
    No worries and not 'unexpected' with the original bags in place.
    Got new ones and had them installed, and 24hrs later...saggy bum.
    I plan to soap the connections when #1 returns it next week, but assuming all is as it might be, where, and for what, do I need to look?


    Thanks in advance...

    Perhaps one of the new bags is faulty? Perhaps a leak on the connection from the hose to the bag? Perhaps a leak in the hose? Does it still inflate or is the pump shot?

    If your car is in a safe place unplug the battery over night, if not unplug all the connectors in the compressor housing(be aware those on the valves have clips at the bottom)...this way you can figure out if it's a management or leak issue cos if it drops without power it's a leak if not it's management...then the diagnose will be better directed

    Thanks for the replies.
    I get the car from #1 on Tues...so 1st thing will be park it up and lift the -ve lead.
    What are the odds, the 'reset' is key?

    Disconnecting the battery won't reset anything, it's just to see if it's management or leak issue as i explained before

    Thumbs up

    So in the end...it all works.
    Original RHR bag must have had a small hole...soapy water couldn't detect, but replaced the bags anyway.
    The return sagging was related to the LHR air line fitting to the bag was leaking...plenty of bubbles.


    Thanks for the replies to this...all are helpful.


    But more, thanks to Matt and the team at Karratha Mechanical Services for their assistance and rectification without any hassle.
