    UDS - Re-adapt Adaptive Suspension to default position -

    Hello....

    After a lot of trial/error and the help from our customer's feedback (Thank You!)
    I have a known working and revised procedure below for the re-adaptation of the UDS Level Controller.
    - Feedback is welcome! -

    This procedure is not for the 'older' non UDS vehicles, this procedure can be found here, 'Suspension Level Calibration'

    How can you tell if you have a 'UDS' Level Controller? Click here UDS vs. Non-UDS
    This is an example of a UDS Level controller when found in the Auto-Scan results:

    Code:
    Address 34: Level Control (J197)       Labels: 3Y0-907-533-V1.clb
       Part No SW: 3Y0 907 553     HW: 3Y0 907 553 
       Component: LUFE-DAEMPFER H16 1095  
       Coding: 008000
       Shop #: WSC 00083 790 00174
       ASAM Dataset: EV_AirSuspe 003017
       ROD: EV_AirSuspe_AU64.rod
    This procedure is applicable for follow vehicles.

    [Coding]
    - If there is an 'incorrectly coded' fault in the [34-Level Control], the controller will need to be coded first, before 'The Procedure' below can be completed!
    - If you have saved an [Auto-Scan] of the vehicle prior to the coding being lost, you can search the scan and copy/paste the coding into the controller.
    - In the unlikely event you have lost coding, create a new Ross-Tech forum thread in the Car Repair Support section and let's see if we can help.


    Special Notes, warnings, etc
    - Do not at any point in time select [Resetting of all adaptations] - If you choose to do so, you will need to make an appointment with your local dealer
    - Make sure you perform and save an [Auto-Scan] before beginning any work
    - If you are attempting to alter the ride height use this procedure at your own risk!
    - If you copy or post this procedure and/or any of its contents anywhere else, please be respectful and give credit where credit is due



    [The Procedure]

    ------------------------------------------------------
    - Re-adapt Adaptive Suspension to default position -

    Select [Adaptation - 10]
    Choose from the drop down menu and enter the [New value] recorded value for each of the wheels below, then press [Do it!]
    - [Body height left front wheel house edge]
    - [Body height right front wheel house edge]

    B.) Using the MMI verify the following setting -
    - Air Spring Wheel Change = [off]

    C.) Ignition Key On/Off Cycle must be completed.

    D.) Clear ALL fault codes and re-check for fault codes, road test vehicle.



    Reference:

    - You may have one or more of the fault codes listed below...

    Small item, there is a redirect file, so label file should probably be 4G0-907-553
    Are you sure odis use that many logins?

    Hi...
    Are you sure odis use that many logins?
    - The last time we received positive feedback, I had a caller on the phone and we did run through the rough draft of the procedure, it appeared that before each of the Basic Settings functions would complete successfully only if the Security Access was used.

    That is a good question though, is ODIS actually doing it the same way with the SA codes?? We have not tested that, ..yet.

    Thanks,

    drpeter
