Coding steering wheel electronics


To make all functions work correctly, the control unit must be coded according to the corresponding equipment.

Note:

Test prerequisites:

Procedure:

  1. Choose the function: "Code control unit".

  2. The actual code in the control unit is presented. "Change value is presented". Confirm with YES.

  3. Enter the new code (see below) in the presented input field, confirm with OK.

    Code number:Function:
    0 X X X XManual gearbox
    1 X X X XAutomatic gearbox
    X 0 X X XSteering wheel without multifunction and Tiptronic control
    X 1 X X XSteering wheel with Tiptronic control, without multifunction
    X 2 X X XMultifunction with scrollfunction
    X 3 X X XMultifunction with radio/phonefunction
    X 4 X X XMultifunction with radio/phonefunction (with voicecontrol)
    X X 0 X XWithout Tiptronic control and steering wheel heating function
    X X 1 X XWith Tiptronic control, without steering wheel heating function
    X X 2 X XWith steering wheel heating function, without Tiptronic control
    X X 3 X XWith Tiptronic control and steering wheel heating function
    X X X 0 XWithout trip computer and cruise control
    X X X 1 XWith trip computer, without cruise control
    X X X 2 XWith cruise control, without trip computer
    X X X 4 XWith trip computer and cruise control
    X X X X 1Without rear window wiper
    X X X X 2With rear window wiper
    Coding example:

    Vehicle with: manual gearbox, multifunction (with scrollfunction), trip computer, cruise control and rear window wiper = 02042

  4. A dialog box will confirm: code stored (with the new value) in memory.

    • If the coding operation fails, check if the code is valid.

  5. Confirm with OK to exit the function.

  6. Switch off the ignition for 60 seconds to store the new code.

  7. Re-establish contact with the system. Read and check the fault codes and the new code.

  8. Exit the function.
