    That may or may not help here but he didn't call or e-mail back so I believe the test drive sorted it. It was unknown if the rack was original or replaced in this case.
    I'm not quite sure if any Ross tech employees found a solution. I took it to a shop and they didn't even know how to do it with VCDS.

    We haven't verified this on a car yet but this should be what ODIS is doing when it runs the G85 calibration, but in VCDS terms:

    1) Test step: Edge detection

    Start the engine
    Point the front wheels straight ahead
    [44-Steering Assist]
    [Security Access - 16]
    Enter 19249
    [Do It!]

    Select these in [Adv Meas Values]:
    [IDE04510-MAS03732] Steering angle sensor: slope detection index - Steering angle speed negative dropping slope on curve
    [IDE04510-MAS03733] Steering angle sensor: slope detection index - Steering angle speed negative rising slope on curve
    [IDE04510-MAS03734] Steering angle sensor: slope detection index - Steering angle speed positive dropping slope on curve
    [IDE04510-MAS03735] Steering angle sensor: slope detection index - Steering angle speed positive rising slope on curve
    [IDE04510-MAS03736]Steering angle sensor: slope detection index - Index mark

    Slowly turn the steering wheel to the right and left, passing the index mark (approx. 45) until all 4 slope detection indexes have been recognised (detected) and the index mark is set to (1).
    [Done, Go Back]

    2) Test step: Steer. angle sens. calibration

    [Basic Settings - 04]
    [Show Measuring Data]
    Select the following items:
    [IDE02216-IDE05795] Steering angle sensor: basic setting - End basic setting
    [IDE02216-MAS03161] Steering angle sensor: basic setting - Start

    In Basic Settings, pick [MAS00815] Steering angle sensor
    [Go!]
    It should show Running


    - Turn the steering wheel slowly to the right and then to the left mechanical stop.
    - Turn the steering wheel back to the mid position, the status should be indicated as Permitted. (IDE02216-MAS03161 or IDE02216-IDE05795 ?)

    Note: in a test on the car it never showed permitted in either of those?

    (after one or both show permitted, stop moving wheel and point straight)
    Wait for it to show Finished correctly?
    [Stop]

    Note: in a test on the car there were no faults and no warning lamps.

    3) Test step: Evaluation of basic setting (no VCDS needed)

    Turn the steering wheel to the right end stop.
    Turn the steering wheel to the left end stop.
    Turn the steering back to its center position.
    Check the yellow fault lamp on the dash.
    The fault lamp on the dash must go out.
    Stop the engine.
    Check and clear DTCs

    First, here is the fault in question:



    So first with the engine running, I went into Adv Meas Values and made sure that the steering wheel was pointed straight and the front wheels were pointed straight, close enough:



    Edit to show identifier for use use with recent versions of VCDS:

    [IDE04448-IDE00924],Steering angle sensor: angle - Steering angle


    Next, I went into Security Access -16 and entered the code that shows up in the little helper balloon and it was accepted.

    Next, I went into Basic Settings - 04 and chose "Steering angle sensor" and clicked [Go!]



    Edit to show identifier for recent versions of VCDS:

    [MAS00815] Steering angle sensor

    Here's the weird part, it showed "Running" but never changed from that. I left it in this mode for 60 seconds then clicked on [Stop] and [Done, Go Back] and [Close Controller, Go Back].

    Next, I cycled the ignition off and back on again. At this point, the TPMS, steering wheel, and ESP lights were still lit up on the dash but a brief drive through a parking lot made them all go away.
    this baloon does not show up when i hover over it in vcds,so i dont know what the security access code is???????????

    Try again in Steering Assist-44, it should pop-up.

    When doing the Basic Settings [MAS00815] Steering angle sensor, did it ever go to "Finished Correctly"?

    We have been testing this test plan last night and this morning on different vehicles within the Ross-Tech fleet, but these have all been vehicles in proper working order.

    The Cliff Notes version of what we are doing:

    Engine at idle.
    [44-Steering Assist]
    Rotate steering wheel 90deg left then center, 90deg right then center so steering wheel is level, front wheels pointed straight ahead.
    [Security Access - 16]
    Enter 19249
    [Basic Settings - 04]
    In Basic Settings, pick [MAS00815] Steering angle sensor
    [Go!]
    Rotate steering wheel all the way to the left, hold firmly against end stop for 5 seconds.
    Rotate steering wheel all the way to the right, hold firmly against end stop for 5 seconds.
    Center steering wheel, front wheel straight ahead.
    Note: our testing of this would still be "Running", never got a message of "Finished Correctly"
    [Stop]
    Now a bunch of error messages and warnings will appear on the cluster, what messages you get can vary based on how the vehicles is equipped.
    [Done, Go Back]
    Rotate steering wheel all the way to the left, hold firmly against end stop for 5 seconds.
    Rotate steering wheel all the way to the right, hold firmly against end stop for 5 seconds.
    Center steering wheel, front wheel straight ahead.
    Now most warning messaged in instrument cluster should be removed.
    [Close Controller, Go Back - 06]
    Cycle the ignition off for 10 seconds.
    Several other control modules will flag DTCs, "Databus" type codes that can now be cleared out.

    Again, we are doing this on vehicles that had no fault codes to begin with.
