    Question Air Suspension wont lower

    After driving up basalt south knob track from Talbotville at weekend the air suspension would not lower from off road height to normal.
    Got messages suspension problem etc. telling me to read manual lights, bongs etc. Despite numerous stops and switching every thing off to reboot system, nothing worked. Drove 250 kms home with suspension at off road height to musical accompaniment.
    Tha handling on road at this height (100kph) was ok, just a bit more rock and roll like my D1.
    Any suggestions of where to start looking. It appears that the system will not vent air in order to lower. Stuck value maybe?

    ps All the post appear to be about supension that sink.

    Maybe a dumb question, but have you checked the fuse ?

    If its just a case of removing the correct fuse to get the suspension to stay up at any speed then that would be a much cheaper option then buying a LAMS kit.

    Well actually removing F26E should achieve that - sort of.

    Well, I would not say that removing fuses is an alternative to the LIAM'S kit, but if the 3 will not drop, that suggests the system is not opening the system exhaust valve that is located within the air compressor.

    I might add that not dropping is sure preferable to "down to the stops", particularly when "out of town" - and also, I have not heard of a post with that concern before either.

    Out in the engine compartment by the starting battery is a fuse box that directs power to the air compressor, and hence the exhaust valve via a 60 amp fusible link 10E, and 20 amp fuse, 26E.

    If either of these are not good, I do not think that the exhaust valve can get power and therefore cannot open to exhaust the air from the air springs. There is also a 5 amp fuse in the interior fuse panel behind the lower glove box, F35P, on a circuit that is energized when the engine is running, however I do not think it in any way powers the exhaust valve but instead provides power to the computer. I think pulling F35P will stop most of the binging bell noises however.

    Update

    Have just walked around the jacked up Disco, got in, turned on key, no orange lights, no messages, started engine, still no nasty messages, light on suspension switch indicated off road mode, carfully pressed switch to normal height, and it then sank slowly to correct height as if yesterday did not happen. Bloody liar.
    I still think that is problem and that it will happen again.
    Not game to raise suspension at the moment

    My comment was very much tongue in cheek.

    Typical D3 computer error.
    Suggest if you have not done already, disconnect the battery so the computer will clear the error, then start over again to see how you go.
    Try all height settings and check if the bells and whistles start up again.
    One last point, sometimes the compressor will start to play up, and work intermittantly, due to age and or grit in the lines restricting air flow, then the computer through the valve starts to show air pressure system failure.
    I would assume that if it rares its ugly head again, a visit to the LR Dealership will be your best option> $$$$$$

    The only hassle rebooting the computer is that any issues logged will also disappear.
    Removing power will not clear stored faults, only that a fault is current. The ecu will log the fault again if its still exists when power is restored.
