    Air suspension problems

    Hello experts,
    Iím planning a big trip around Australia next year and getting my D3 ready. It currently has 234k km on the clock.
    Question: based on current km, can I expect air suspension parts to start failing on me soon? What is the first thing I should start looking as potential problem? Any signs of wear I can look for?
    So far everything is working fine.
    Oh, and Iíll be towing 2.5t van

    Thanks,
    Seb

    I know what Iíd be doing before a ďlapĒ with that many Kms on the clock plus towing a van

    - airbags
    - shocks
    - compressor
    - wheel bearings
    - gearbox, engine and transaxle lubes
    - cooling system and AC service
    - maybe LCAís

    Seriously thatís a lot to ask an old girl to cope with, without doing some serious preventative maintenance

    Just buy an ex Wicked bongo wagon as they seem to be capable of endless laps of Australia requiring nothing but fuel top ups.

    Iíd bet the Disco would do it fine still but at least get those components closely checked if you donít know the history of them well.

    Additionally;
    Coolant flush
    New water pump
    Replace plastic coolant fittings

    Thanks Brian,
    Grearbox and rear diff getting reconditioned later in the yaer. Front already done.
    Cooling system definitely something to inspect.
    Is there a way to determine how close compressor and air bags are from failing?

    If there are no suspension faults being logged, the EAS compressor is probably OK. You should however, change the dessicant in the compressor drier and upgrade the the drier cap. You can test the bags and EAS system by removing the EAS fuses and checking for sag overnight. I believe leaving a door ajar also defeats the EAS valves. If it sags look for air leaks with a spray bottle with soapy water.
    The suspension lower control arms (LCA) bushes and/or swivel joints, usually become cluncky at about 200K, so I would check as they may have already been done

    Thanks, much appreciated. Will check for any leaks like you mentioned.
    LCAs were checked and so far nothing loose yet, but I think they will have to go on the list nonetheless

    You can really go overboard on preparation and replace everything (of course many do nothing).

    For the suspension I would get the compressor rebuilt before you go - probably $120-$150. Buy an o ring kit to rebuild the valve blocks if they were to play up. Airbags do not have a history of failure even at high km so a failure would be the exception - visual inspection is probably OK.

    I would invest in a EAS emergency inflation kit - GOE used to do them but it would seem they no longer make them so research how it is done and build one.

    As far as the suspension is concerned I dont see any other prep is needed.

    Is the trip mainly on the highways or will there be some remote off-roading as well? If you are going places were you canít get help from RACQ etc, then thatís another level of preparation.

    If you are going remote, critical components should be changed by age not by waiting for the first signs of failure. What age? If you are asking for signs of failure then itís probably time to replace. I know itís tempting to get as much use from a component that you can, especially if itís an expensive component but itís not worth getting stuck in the middle of nowhere.

    How old is the compressor? It might seem fine when you leave home but itís a big trip. If itís the original, replace it you have definitely got you moneyís worth. If itsís not the original but has done say 150,000kms I would think about replacing it and keep it as a spare.Thatís what I did.

    Airbags rarely fail catastrophically but the shock absorbers get soft usually giving a wallowing feeling. New airbags will definitely help with towing. If these are the originals then it might be time to replace.

    Alternator maybe if it is the original.

    The upper water housing under the throttle body.

    Airbags, compressor and alternator, water housing are quite easily done at home. If I can do it than anyone can. Source the parts from the UK and install yourself and you will save a lot.

    The more hands-on I get with the vehicle the more confidence I have in the vehicle and in my my ability to resolve potential problems when off-road. DIY is not just about saving money.

    Enjoy your trip.

    Awesome. Thanks for your feedback guys!
    Air compressor on the to do list as well
    Alternator replaced last month.

    Our trip will be mainly coastline with finding as many beautiful beaches as possible There will definitely be corrugated roads and sand driving, donít envision much if any proper off road tracks.

    Looks like you have it pretty much sorted.
