    I think that the software update should be listed on Landrover GTR, but if you have a look , there are several tsb's relating to air suspension.
    This may be applicable to yours.

    Technical Service Bulletin

    2 . Remove the EAS main fuse (F57 of the passenger compartment fuse box) to prevent any ECU activity.
    3 . Disconnect the pressure sensor electrical connector.
    4 . WARNING: Some residual pressure may remain in the reservoir. Use eye protection.

    CAUTION: To avoid EAS system moisture contamination, do not allow the reservoir to be exposed to atmosphere for long periods.

    Remove the pressure sensor.


    5 . Visually inspect and clean the threads of the pressure sensor mounting in the reservoir.
    6 . Install a new pressure sensor using the new gasket supplied and tighten to 9.8Nm +-1Nm.
    7 . Connect the pressure sensor electrical connector.
