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 XStandard steering wheel without multifunction
    1 X X X3-spoke steering wheel (sport steering wheel)
    2 X X XMultifunction with scrollfunction
    3 X X XMultifunction with radio/phonefunction
    4 X X XMultifunction with radio/phonefunction (with voicecontrol) or mobil phone preparation or North America telematik
    5 X X XMultifunction with radio/voicecontrol (without phone)
    X 0 X XWithout Tiptronic control and steering wheel heating function
    X 1 X XWith Tiptronic control, without steering wheel heating function
    X 2 X XWith steering wheel heating function, without Tiptronic control
    X 3 X XWith Tiptronic control and steering wheel heating function
    X X 0 XWithout trip computer, cruise control and adaptive cruise control
    X X 1 XWith trip computer, without cruise control and adaptive cruise control
    X X 2 XWith cruise control, without trip computer and adaptive cruise control
    X X 3 XWith adaptive cruise control, without trip computer and cruise control
    X X 4 XWith trip computer and cruise control, without adaptive cruise control
    X X 5 XWith trip computer and adaptive cruise control, without cruise control
    X X X 1Limousine
    X X X 2Avant (with rear window wiper)
    Coding example:

    Vehicle with: multifunction (with scrollfunction), trip computer, cruise control and Avant = 2042

  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.
