    Touareg 7L air suspension problems

    Got here 05, 7LA Touareg, Im normally ok with the air suspension on the VAG range but this one is kicking my butt, the arse end was in the air and it was bouncing along, it would not lower, I put 2 new genuine residual pressure valves on the rear airsprings, manually removed the pressure from the system to level the vehicle, In basic settings I can fill, bleed, empty, lower raise the vehicle no problems but when I get to last stage of calibration in adaption, Channel 05 (confirmation) I always get error when Im clicking from 4 up to 5, any clues why

    Thanks

    Do whatever is necessary to get the vehicle reasonably level and at something resembling normal height and then look through the Measuring Blocks in the 34 - Level Control module to see if one of the height readings is substantially different than the other three.

    Sensor mechanical basic setting invalid?

    Did you consider must be set manually to achieve range desired of target in controller for adaptation or value input is implausible target?

    All sensors have been checked, I depressurized the system, checked low reading of sensors then slowly jacked each corner also with scope pinned to module to make sure there was no dropouts, when the "wait" command it displayed it does sort itself out to normal level.

    I did set it manually by measuring each corner, there's only about 10mm difference, battery charger?, I dont think its needed as this has to be done with the engine running

    Any other clues
    Thanks

    Okay dismiss me, however, you do realize I'm not speaking of measuring sweep with meter/scope or speaking of electrical faults, I am speaking of range of mechanical basic setting of physical sensor placement or rod to sensor?




    01400 - Suspension Level Control
    001 - Upper Limit Exceeded - Intermittent

    Clue......
    Did you even read the DTC reported?

    If you change position slightly can you vacate DTC and complete the adaptation?

    Ive read this:

    Possible Causes
    Leakage
    Excess Temperature Shut Off


    Possible Solutions
    Check System for Leaks
    See Factory Repair Manual for Details
    Let the System cool down before any further Attempts


    Ive no idea what the operating temperature is on these compressors, Ive had the compressor lying on the cold stone floor waiting for it do something, it would be nice if it did cut off due to overheating at least then I know its tried

    Im 110% sure its got no leaks, thats been checked and checked again

    Ive got in MB's 005

    LF(G78).............RF(G289).............LR(G76).. ...........RR(G77)
    ...90.0...................112.0.................11 2.0.................114.0

    Im thinking maybe left front as its 12/4 mm lower maybe causing the problem but I also though thats why the system needed calibrating to even them all out

    any more clues

    Thanks

    Did you know electronic calibration can only be done if mechanical components measured basic settings are in criteria range to permit it to achieve an adaption point to point & too establish the full RANGE?

    If we count one (what Jack wrote) plus one (Your measurements), what should we get? Maybe five?
    LF(G78).............RF(G289).............LR(G76).. ...........RR(G77)
    ...90.0...................112.0.................11 2.0.................114.0

    But ok, if You said, LF is really physically lower, then do couple other tests (on level surface, of course) - lower vehicle as low as it is possible, check all level measurements, and lift it as high as possible and check measurements again.
    In some position one or more measurements may go outside of acceptable range, so it may cause the DTC 01400 - Suspension Level Control
    001 - Upper Limit Exceeded - Intermittent
