    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...
