    deflated air spring

    Leaving the car park last night I passed a D2 that was sitting on it's bump stop on one corner. It got me to thinking I have no idea what to do should the d3 'get a flat'.

    Any suggestions fo what to do should this problem occur?

    I've heard and seen youtube footage of older LRs doing it.....it plays with your head. When I was off-road I heard this massive bang from somwhere under my D4 but no impact at all. Tyre or air-bag I assumed. Stopped, got out, checked everything....all OK. Only contender was a broken tree root coming out from the forest. I'm assuming my 2.6 tons and it had an arguement.

    Scared me thou...

    Only ever heard of one failure. Coming off a dune in Morocco with heaps of air and landing nose heavy.
    It was not the bag that went but just the connector on top.

    Failure of other parts of the air system is more likely. There has been proposed a cut to the airline and a valve attachment to manually pump up each corner in an emergency.

    Block Valves are pretty reliable as well.

    Yes, fortunately, the air spring rubber bags seem quite reliable. They may over time develop slow leaks, but actual blowing out fortunately seems not to happen.

    Also the block valve assemblies, while they do give some trouble, seem to work pretty much OK as well. Where there are problems, it seems to relate to internal corrosion of the conductors within the wiring harness to the block valves, or a corrosion related fault within a wiring harness connector.

    The attached link is from a Norgren website. It appears that Norgren, (a British company), is the supplier of the block valves to Land Rover. I get the impression however, that while Norgren makes air line connectors as well, that it is not the Norgren tubing connector that is on the block valve, but the Voss connector. The pictures on the link below seem to show Norgren connectors rather than Voss.

    Now, if Land Rover could just solve the compressor reliability concern.

    All things considered, installing a T in each air line to an air spring does provide a workaround for all problems other than an actual bag blowout or failure of the tubing or connectors between the air spring and block valve.
